Pooling Administration System (PAS) Accounts
As a consultant for one or more service providers, what is required of me before I request a user id and password for PAS and/or add additional OCNs to my existing PAS user profile?

All consultants who register as a new PAS user or add OCNs to their existing PAS user profile must have a letter of authorization (LOA) on file for each service provider for whom they intend to submit pooling requests.

The LOA should:

  • Be on the company letterhead of the service provider.
  • List the authorized consultant’s name (or consultant’s company name).
  • Indicate that the consultant is authorized to have access as a user in PAS, and can act on the service provider’s behalf for submission of numbering requests.
  • List all OCNs for which the letter applies.
  • Have the authorized representative of the service provider’s contact phone number and email.
  • Be signed by an authorized representative of the service provider. 
  • Must be dated.
The LOA should emailed to support@nanpa.com.
Why am I prompted to change my password when I login to PAS for the first time after receiving a new password? This is a security feature that has been put in place to protect users so that no one other than the user has their password. Once you have logged in and been issued the new secure password be sure to retain the password for future use.
Can more than one person share a PAS User id and password? No, user ids and passwords cannot be shared per the FCC security requirements. If the login administrator has determined that you are sharing your user id and password the user id will be immediately disabled.
If I forgot my password for PAS, how can I obtain a new password?
You will need to send an email from the email address provided in your user profile to support@nanpa.com requesting a new password.  Please include within the email your PAS user id (login id) and specify that this is a request for a new password.  A pooling representative will email you a temporary password to the email address provided in your user profile. 
If I forgot my user id for PAS, how can I obtain my user id? You will need to send an email from email address provided in your user profile to support@nanpa.com requesting your user id information.  Please include within the email your name, company name and specify that this is a request for your PAS user id.  A pooling representative will email you your user id to the email address provided in your user profile.
What I if keep trying to login and keep getting an error message? Your PAS account may have been disabled. Your PAS account can be disabled for the following reasons:
• PAS users will be disabled after three unsuccessful login attempts.

New PAS users will be disabled if they fail to contact the Number Pooling Customer Support desk for their password and log into PAS within ten days of receiving their new PAS user id via email.

Existing PAS users will be disabled if they do not change their password in PAS within ten days of receiving the password expiration email.

You will need to send an email to support@nanpa.com to request that your account be reactivated. Please include within the email your PAS user id (login id) and specify that this is a request to reactivate an existing PAS account. Also include a telephone number where you can be reached. A pooling representative will contact you.
How often do I need to reset my password for PAS? PAS passwords expire 120 days from the date of issuance. You will receive an email notification ten calendar days prior to password expiration. You must login to PAS and reset your password within ten calendar days of receiving the “Password Expiration” notification; otherwise your account will be disabled. If the password has not been reset by three days prior to expiration, a second and final email reminder will be sent.
General PAS Questions
Is there a PAS User Guide and if so, where can I find it? Yes there are User Guides for PAS. The following User Guides may be found on the Pooling website (www.nationalpooling.com) under Documents and then PAS User Guides (All).
  • PAS Regulatory User Guide for Registration
  • PAS Regulatory User Guide
  • PAS Service Provider and Service Provider Consultant User Guide for Registration
  • PAS Service Provider and Service Provider Consultant User Guide

What effect does a pop-up blocker have on PAS? If you have “Pop-Up Blocker” software installed on your internet browser (i.e. Internet Explorer, Mozilla Firefox), please adjust the settings to always allow pop-ups from the Pooling website (www.nationalpooling.com). Failure to do so could prevent you from receiving the session timeout messages from PAS.
Is there a time-out feature in PAS? Yes, PAS will automatically time you out of the current session after 30 minutes of inactivity; however, you will receive a pop-up warning after 25 minutes of inactivity. By clicking the OK button on the pop-up, this will extend your current session for another 30 minute period.
While working in PAS, why doesn’t PAS provide me with a time-out warning? If you have “Pop-Up Blocker” software installed on your internet browser (i.e. Internet Explorer, Mozilla Firefox), please adjust its settings to always allow pop-ups from the Pooling website (www.nationalpooling.com). Failure to do so could prevent you from receiving the session timeout messages from PAS.
Why am I not receiving an email notification once the PA issues a Part 3A? There can be several reasons that you may not be receiving emails from PAS.  First check the email address in your user profile to be sure it is up to date.  If you have “Spam Blocker” software installed on your email server (i.e. Microsoft Outlook), please adjust its settings to always allow emails from the somos.com email addresses (ex: support@nanpa.com).  Failure to do so could prevent you from receiving email notifications sent from your Pooling Administrator and/or emails from PAS.
When I am out of the office, how can my back-up be notified about my pending PAS requests? Prior to leaving the office add your back-up to your PAS profile as an additional contact.
What happens if I accidentally delete a work item in my PAS Work Item Summary List? Does this change anything relative to the actual work I’m doing in PAS? Or do I just lose the "tracking" ability provided by PAS? If you accidentally delete a work item in PAS it will not negatively impact the particular transaction tied to that work item. You will, however, lose the tracking ability provided by the PAS Work Item Summary List.  You will still be able to find forms associated to the deleted work item by going to Search Forms located in the tools frame and selecting View Form or List Form to review the status of the requests.  You can also go to Reports located in the tools frame and select Part 1/1A Report, or Part 3A Report, to review the status of requests.
Are the PAS work items in my Work Item Summary List automatically removed after a period of time, or am I the only one who can remove them? Your work items will automatically be deleted from the Work Item Summary 30 days after the Work Item Create Date. You also have the option of deleting a work item from your Work Item summary at any time. Refer to the PAS SP and SPC User Guide, Section 11.3.2 for details.
Why are there, both PAS generated emails and PAS work items for the same items? PAS is providing you with two different ways to locate responses from the Pooling Administrator for processed requests. You have the option of deleting any or all of these emails and work items at any time.
Once I request and receive a code to establish an LRN, can I request additional blocks using that LRN? Yes, you can request additional blocks, however, additional blocks should not be requested with an effective date prior to the effective date of the LRN.
Reports
Where can I locate a list of assigned thousands-blocks? You can locate this information on the www.nationalpooling.com website. Go to “Reports”, select “Block Report”, select the state, NPA, rate center then select the “Assigned Blocks” radio button, and click “Continue”. You can also download or print the resulting list of assigned thousands-blocks.
Where can I locate a list of available thousands-blocks? You can locate this information on the www.nationalpooling.com website. Go to “Reports”, select “Block Report”, select the state, NPA, rate center then select the “Available Blocks” radio button, and click “Continue”. You can also download or print the resulting list of assigned thousands-blocks.
Where can I locate a list of retained thousands–blocks? You can locate this information on the www.nationalpooling.com website. Go to “Reports”, select “Block Report”, select the state, NPA, rate center then select the “Retained Blocks” radio button, and click “Continue”. You can also download or print the resulting list of assigned thousands-blocks.
If I want to pull a report for more than one NPA at a time for the blocks available, or assigned, or retained report, how can I do that? You can pull these reports by region. You can locate this information on the www.nationalpooling.com website. Go to “Reports” then select “Block Report by Region”.
How can I pull a report for all available, assigned and retained blocks? On the “Block Report by Region” page, at the bottom of the page there is a section for “All Regions”; click on “Blocks Available, Assigned & Retained (zip), then click on “Open”. The combined Blocks Available, Assigned and Retained file, will be in a text (ASCII, comma delimited) file for each region. You may also select “Blocks Available, Assigned, & Retained (zip) (Augmented) The augmented version of the report will include two additional fields: “Region” and “State”, and it will also include an additional block status called “AP” (Available Pending Blocks).
Am I able to print reports? Yes, you can print reports from both the Pooling website and from within PAS.
How far back do the reports in PAS go? You have the ability to pull reports going back to the inception of pooling in 2002.
General Pooling Related Questions
How do I determine if a rate center is in pooling or not? You can locate this information on the www.nationalpooling.com website. Go to Reports, select NPA/Rate Center Reports, enter the state and NPA then click Continue. This will bring up a list of rate centers with their current pooling status. Click on the Pooling Status Designations button at the bottom of the report for a legend of pooling status designations.
How do I opt into pooling in an excluded rate center? An SP can request at anytime that the PA open up an Excluded rate center to Optional pooling. To accomplish this the SP would need to email the Customer Support Desk at support@nanpa.com  In their email the SP should request that the Excluded rate center in an NPA be opened up to Optional pooling.

Once the updates have been completed the SP may submit a forecast, a block disconnect/donation or a new resource request in PAS.
If I choose to participate in Thousands-Block number pooling in an optional rate center, can I withdraw from pooling in that optional rate center at any time? No, you cannot withdraw from pooling once you’ve submitted a forecast, a Thousands-Block disconnect/donation to add Thousands-Blocks to the pool, or if a Thousands-Block has been assigned to you.
How do I determine if a Thousands-Block is contaminated or not?

We recommend that you query the NPAC to determine if a Thousands-Block is contaminated. For assistance with performing the NPAC queries, contact the NPAC help desk at 844-820-8039.

Another way of determining if a Thousands-Block is contaminated or not, is by going to “Reports” located on the www.nationalpooling.com website. Select “Block Report”, then enter the state, NPA, rate center and select the “Available Blocks” radio button, then click “Continue”.  Under the “Contam (Y or N)” column, if there is a “Y” then the thousands-block has been reported as contaminated. If there is a “N” then the thousands-block has been reported as pristine. 

Thousands-Block Donations/Disconnects
What happens if I donated/disconnected a Thousands-Block in error?

Section 11.1.8 Blocks Returned in Error, of the Thousands-Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines (TBCOCAG) describes what steps can be taken to retrieve a Thousands-Block returned in error.   “If a SP returns a Thousands-Block to the PA in error and the Thousands-Block disconnect application has been processed but the Effective Date of the return has not yet passed, the SP may cancel the Thousands-Block return in the Pooling Administration System (PAS).
If a SP returns a Thousands-Block to the PA in error and the Thousands-Block disconnect application has been processed, but the Effective Date of the return has passed, and the Thousands-Block is still Available in the Industry Inventory Pool, the SP may retrieve the Thousands-Block by submitting a Part 1A.”  Refer to Section 11.1.8 for additional details. 

What steps must I take prior to donating/disconnecting a Thousands-Block?

Section 8.3.4e of the TBCOCAG outlines what steps the CO Code Holder must perform prior to donating/disconnecting a Thousands-Block:

e)  confirm, prior to donating/returning any Thousands-Block to the Industry Inventory Pool, that:
1)  all Unavailable TNs (any numbers classified as Administrative, Aging, Assigned, Intermediate, or reserved) within contaminated Thousands-Blocks have been Intra-Service Provider (ISP) Ported;
2)  the Thousands-Block has been protected from further SP number assignment;
3)  the associated Non-pooled CO Code(s) is currently available for call routing, is flagged as Local Number Portability (LNP) capable in the LERG Routing Guide and the NPAC, and the NPA-NXX query triggers are applied in all switches and reflected in the appropriate network databases (e.g., STP routing tables);
4)  the Non-pooled CO Code’s -Assigned Switching Entity/POI is currently LNP-capable and shall process terminating traffic appropriately; and   
5)  interconnection facilities have been established between the Non-pooled CO Code’s Assigned Switching Entity/POI and other interconnecting networks;
6)  the Thousands-Block identified for Donation/return does not contain a test line number.  If a Thousands-Block being donated/returned contains a test line number, the CO Code Holder shall disconnect the test line number before donating/returning the Thousands-Block.  The test line shall be re-Assigned to a number in a Thousands-Block retained by, or Assigned to, the CO Code Holder;
7)  the Thousands-Block identified for Donation/return does not contain a Location Routing Number (LRN). If a Thousands-Block being returned or donated/returned contains an LRN, the CO Code Holder shall migrate any ported numbers or pooled Thousands-Blocks utilizing the LRN to another LRN within a Thousands-Block retained by or Assigned to the CO Code Holder, and delete the LRN from the NPAC and the LERG Routing Guide before donating/returning the Thousands-Block. LRNs shall only be established in Thousands-Blocks retained by, or Assigned to, the CO Code Holder;
8) the Thousands-Block identified for Donation/return does not contain more than 100 Unavailable TNs. This includes the donating/returning CO Code Holder’s Unavailable TNs and all other ported TNs identified in NPAC to other SPs

When should we donate/return Thousands-Blocks to the pool?

The FCC permits service providers to maintain up to a six-month inventory.  Any thousands-blocks (ten percent contaminated or less) in your inventory that you do not anticipate using in the next six months should be donated/returned to the pool.

See also section 14.1.7.1 of the (TBCOCAG) for additional information regarding donations/returns.
What do I need to do after my donations/returns have been processed and accepted by the PA?

Per Section  17.2.5 of the TBCOCAG:
“When the CO Code is a Non-pooled Central Office (CO) Code (NPA-NXX), the SP shall build the records for any Thousands-Blocks being retained on the NXD screen for the Thousands-Block being donated/returned after the PA has processed the request. At the time the PA approves the disconnect application, the PA shall update the BCR record in BIRRDS with the Effective Date indicated on the Part 3A Pooling Administrator’s Response/Confirmation.”

This means that for any Thousands-Block within the CO Code that has been retained, your AOCN needs to go into BIRRDS and create the NXD records. For example if you disconnect/donate NPA-NXX-1,2 and 3, your AOCN would need to create NXD records for NPA-NXX-0,4,5,6,7,8 and 9.


Thousands-Block Forecasts
How often do I need to submit a forecast?

Section 4.4. of the TBCOCAG directs SPs to "submit their NRUF to the NANPA on a semi-annual basis on or before February 1 for the period ending December 31 and on or before August 1 for the period ending on June 30 of each year.  Additionally, under these same semi-annual reporting deadlines, SPs shall submit to the PA the Appendix 4." 

In addition, if you do not have a forecast on file at the time you are submitting a request for resources you must submit a forecast prior to submitting your request.


Once I submit a forecast, can I change it? Yes, a forecast may be updated at any time.
Do I enter the number of TNs (telephone numbers) or the number of Thousands-Blocks on the forecast form? You should enter the number of Thousands-Blocks in the month(s) in which you anticipate making requests for resources in each of the given rate centers.  If a full CO Code is needed, it must be reflected in Thousands-Blocks, e.g. a full NXX = 10 Thousands-Blocks.
If I made an error on my forecast submission, can I have that forecast removed from PAS? No, forecasts may not be deleted from PAS; however, you can modify your forecast with the correct forecast information or change the forecasted amounts to all zeros.
Is there a way to track forecast submissions or modifications to an existing forecast in PAS? No, PAS does not report historical information on forecasts.
Once you submit a new forecast or modify an existing forecast in PAS, how soon is PAS updated? Your forecast is updated immediately. Upon successful submission you will receive the following confirmation message; “Your forecast has been successfully submitted”. You can also go to Reports located in the PAS tools frame and select Forecast Reports to verify that your forecast was submitted or updated successfully.
Is there an easier way to submit a zero forecast for multiple rate centers? Forecasts can be submitted for multiple rate centers in the same NPA within one submission. From the tools frame to the left of PAS select Submit Forecast, then Create/Modify Forecast. This will bring up the “Thousands Block Forecast” selection box. Enter the NPA, First Month, and OCN then click “Continue”. From the Thousands Block Forecast Report page, you can select a rate center from the drop-down list. PAS enters zero as the default forecast amount for 12 months. Click “Populate” to add a forecast for 12 months, and then repeat for as many rate centers as needed. Once all desired rate centers have been added to your forecast click on “Submit Forecast” at the bottom of the Forecast screen.
If I don’t request a block in the month I forecasted a need, will my forecast roll over to the next month? No, PAS will not rollover your forecast from month to month.
Can I submit my forecasts via FTP? Yes, you can submit your forecasts via SFTP. Additional information and a Secure FTP Registration form is located under Documents on the pooling website. For additional questions or information regarding SFTP you may contact the customer support desk via email at support@nanpa.com or via phone at 1-866-623-2282.
Block Reservations
When can a block reservation be requested? A SP may request to reserve a Thousands-Block(s) once a state waiver request has been submitted to the appropriate regulatory authority.  For more information refer to Section 6 of the TBCOCAG.
For my block reservation what do I need to provide that shows that a state waiver has been submitted? The SP shall include a note in the Remarks section of the Part 1A or send an email to the PA that includes the following information: the date the waiver was submitted, the denial tracking number from PAS for the waiver request (if available) and the tracking number from PAS of the reservation.
How long is a block reserved for?

A block will remain in reserved status until:

  • A SP requests assignment of the reserved block
  • A SP requests cancellation of the reserved block
  • Block reservations are reserved for 3 months from the Part 3A date approving the reservation. The block reservation will automatically be cancelled and the block returned to the pool one day after the original block reservation expiration date listed on the Part 3A approving the reservation unless an extension is requested prior to the reservation expiration date.
  • When an extension has been requested the block reservation is extended to 6 months from the Part 3A date approving the reservation, (i.e. the SP requested a 3 month extension prior to the original 3 month reservation expiration date). The block reservation will automatically be cancelled and the block returned to the pool one day after the revised block reservation expiration date provided on the Part 3A that approved the extension.

Part 1A Form and Part 1 Forms
What is the standard thousands-block effective date? According to section 5.1.7 of the TBCOCAG, the standard block effective date is 31 calendar days from date of application, however, SPs must allow at least two calendar days beyond the Effective Date prior to activating TNs with the assigned Thousands-block.
What is an expedited effective date and how do I indicate this on my Part 1A form?

According to Section 5.1.7a of the TBCOCAG, an expedited effective date is a date earlier than the standard thousands-block effective date (31 calendar days). 


a)  The requesting SP shall indicate on the Part 1A that this is an expedited application with its desired Effective Date.
1)  To expedite all Thousands-Blocks in a multi-block application, the requesting SP shall select “Yes” for Request Expedited Treatment.
2)  To expedite one or more but not all Thousands-Blocks in a multi-block application, the SP shall select “No” for Request Expedited Treatment but shall include a statement in the “Remarks” field indicating which Thousands-Block(s) is/are to be expedited.

b)  The PA shall process the application if the application meets the criteria for the Allocation of the Thousands-Block(s) and shall make every effort to process the application in fewer than the current maximum seven calendar days. The PA shall expedite such applications when it can do so without failing to meet its seven-calendar day application processing interval for other SPs. The PA shall determine the minimum Effective Date for an expedited application based upon the following considerations:
1)  In the case of a new Thousands-Block application, if the Applicant is the CO Code Holder of the Pooled CO Code, and no NPAC notification is required, the Effective Date shall be at least nine calendar days after the issuance of the Part 3A Pooling Administrator’s Response/Confirmation. This allows for the PA and AOCN to update BIRRDS for LERG Routing Guide daily updates. The AOCN shall agree to perform the BIRRDS update in two calendar days rather than the usual seven calendar days.
2)  In the case of a new Thousands-Block application, if the Applicant is not the CO Code Holder of the Pooled CO Code, the Effective Date shall be no earlier than eight business days after the issuance of the Part 3A. This allows for the PA and AOCN to update BIRRDS for LERG Routing Guide daily updates. The NPAC shall build the Thousands-Block in the NPAC within three business days. The AOCN shall agree to perform the BIRRDS update in two calendar days rather than the standard five calendar days.
3)  As soon as all NPAC processing and notifications have occurred, the SP shall activate the Thousands-Block and can begin customer assignments from a new Thousands-Block.

NOTE: SPs requesting expedited treatment of Thousands-Block(s) should be aware that there may be potential impacts to other SPs and customers. This may affect customer service to the extent that a SP is unable to identify the SP to whom a Thousands-Block has been Assigned when responding to a customer trouble report.

If the user enters an effective date other than the default effective date, then the PA will use the requested effective date as long as it meets requirements in the TBCOCAG guidelines.

 



When I submit a request for a Pooled CO Code in PAS do I need to send anything to the PA? If the CO Code request is an initial request, you will need to send your certification or license and proof of facilities readiness to the PA.  Interconnected VoIP providers will also need to send the 30-day state notification for both initial and growth requests.  The TBCOCAG sections 4.8.1 and 4.8.2 lists the acceptable forms of certification and proof of facilities readiness.
What should I do if I notice an error on a request that I just submitted? If you made an error on a new Thousands-Block request that was just submitted, you can modify that request in PAS as long as the PA has not opened the request for processing or it has not been more than 5 calendar days since you submitted the request.
Can my co-worker modify a request on my behalf? Yes, any user that has the same state, NPA and OCN in their profile will have the ability to modify a pending new block request as long as the PA has not opened the request for processing or it has not been more than 5 calendar days since you submitted the request.
Is there a way I can save a Part 1A Request in PAS? Yes, for new block requests you may save the request at any time during the application process. To save your work, click the “Save” button at the bottom of the screen and the application will be saved.
How long will my request remain saved? Your request will be saved for 30 days from the date the request was first saved. After 30 days, PAS will automatically remove the request from PAS.
Can I pull up a co-worker’s saved requests? Yes, as long as you have in your profile the same OCN, State, and NPA as the user who originally saved the request.
Can I submit a block transfer through PAS? Yes, Thousands-Block transfers can be done through PAS as an ‘Inter OCN’ Block Modification request. See Section 9.1.9 of the TBCOCAG for more information.
State Waivers
Does PAS issue a denial for a State Waiver? Yes, if you do not meet MTE and/or utilization, PAS provides a radio button ‘Need to Request a State Waiver’ that you may select. If this button is selected, PAS will process an automatic Part 3A denial so you can proceed with requesting a state waiver from the appropriate commission.
Do you have to completely re-enter a new request after you receive the approval from a state commission? Yes, a new request will need to be filled out and submitted at the time you receive a state waiver approval from the commission. You must attach a copy in PAS or send a copy via email of the approved waiver the same day as you make your request in PAS.
Part 1B Form
Who do I contact if my Part 1B is rejected? For questions regarding Part 1Bs please contact the NPAC Pooling Team at npac@iconectiv.numberportability.com and you will receive a response or if requested, a call back within 1 business day.  The NPAC Pooling Team can provide information regarding why the block request was rejected, however they cannot process the rejected block request.  The request must be resubmitted through PAS with the correct information before the NPAC Pooling Team will be able to schedule it in the NPAC.  Note: Resubmission of a rejected block request will change the effective date.  An expedite may be requested in PAS when the request is resubmitted if the block request is time critical.
How do I properly identify on the Part 1B form whether I should mark the NPAC Activate as Yes or No?

By marking the activate radio button as "Yes", the NPAC will schedule and activate the block range.  By marking the activate radio button as "No", the NPAC will schedule the block range but it will be the responsibility of the SP to activate the block range. By marking the "For Information Only" checkbox, the NPAC will not activate the block range regardless of what was selected for NPAC Activate Yes or No. You may contact the NPAC Pooling Team at npac@iconectiv.numberportability.com for further details. For more information on Part 1B activations and NPAC refer to Section 7.1.18 of the TBCOCAG.

What happens if I enter wrong Point Codes (DPC, SSN, etc) on the Part 1B forms? Entering incorrect information for DPCs and SSNs is service affecting. Point Codes are used in SS7 message routing. The PA will not be able to assist you in determining correct Point Codes. Check with someone within your company who is familiar with SS7 or your SS7 Vendor for correct DPC and SSN information in order to avoid complications and call failure issues. The request must be resubmitted through PAS as a modification with the correct DPC or SSN information before the NPAC Pooling Team at npac@iconectiv.numberportability.com will be able to correct it in the NPAC.
What happens if I enter the wrong LRN on the Part 1B forms?
Entering incorrect LRN information is service affecting. The PA will not be able to assist you in determining correct LRNs. Service Providers are responsible for ensuring that the correct LRN is listed on the Part 1B form and ensuring that this same LRN is loaded in the NPAC. The request must be resubmitted through PAS as a modification with the correct LRN information before the NPAC Pooling Team at npac@iconectiv.numberportability.com will be able to correct it in the NPAC.
On the Part 1B form, when should I check 'For Information Only'? You would check 'For Information Only' when there is no NPAC action required.   For more information on Part 1B activations and NPAC refer to Section 7.1.18 of the TBCOCAG.
If I submit a new code request and I want the blocks that I keep to be activated in the NPAC, how do I accomplish that? Once the Thousands-Blocks have been assigned to you, then you can submit a block modification request in PAS and select ‘Part 1B’ as the type of change, then indicate “Yes” on the Part 1B for ‘Will block X of X be activated by NPAC’ and “No” on the Part 1B for “Is block being allocated back to the code holder on the switch where the NXX Code Resides”.
Months-to-Exhaust Worksheet
When do I need to complete the Months-to-Exhaust Worksheet? When you request additional thousands-blocks within a NPA and rate center where you currently have resources assigned.  You will need to meet the 6.0 month-to-exhaust requirement and the minimum 75% utilization requirement in order to obtain additional Thousands-Blocks for growth within an NPA and rate center.
How do I calculate the utilization level? Per FCC 00-104, § 52.15 (g) (3) (i) (ii) “The numbering resource utilization level shall be calculated by dividing all assigned numbers by the total numbering resources in the applicant’s inventory and multiplying the result by 100. Numbering resources activated in the LERG™ Routing Guide (LERG) within the preceding 90 days of reporting utilization levels may be excluded from the utilization calculation.”
Part 4A Form
Can I reply to the ‘Confirmation of Thousands-Block In Service - Part 4A Reminder' email with my Part 4A form? No, you must submit your Part 4A directly into PAS, which updates your Part 4A record immediately. 
How many customers do you have to have on a block in order to submit a Part 4A? You must have at least one customer on the Thousands-Block in order to submit a Part 4A to acknowledge that the Thousands-Block is in service.  “In service” is defined in the TBCOCAG , “A Central Office (CO) Code (NPA-NXX) or Thousands-Block (NPA-NXX-X) for which local routing information appears in the LERG™ Routing Guide, and one or more Telephone Numbers (TN) within the CO Code or Thousands-Block has been Assigned to an end user (FCC 00-104, ¶240).  Numbers that are categorized as Administrative, Aging, Intermediate, Reserved, or Available cannot also be Assigned and do not satisfy the In Service requirement.”
If I request an effective date change for my new block assignment, will my Part 4A due date change? Only if you request an earlier effective date than what was previously assigned to you. Then your Part 4A due date will be based on the new effective date.
How do I extend my Part 4A due date? To extend a Part 4A due date the user must contact the appropriate state commission or the FCC (if the state does not handle the reclamation process) to request an extension of a Part 4A due date.
Part 5 Form
What is the purpose of the Part 5 form? As a Code Holder, why do I receive the “Part 5 Approved by NPAC” emails? If a Thousands-Block is voluntarily returned via a Part 1A or reclaimed by a state commission or the FCC, the PA will complete sections A and B of the Part 5 form and forward it to the NPAC. The NPAC will then complete section C of the Part 5 form and notify the PA, the CO Code Holder, and the block holder that the Thousands-Block has been removed from the NPAC. The CO Code Holder is part of this notification process so that they can provide the blank and vacant code announcements for this Thousands-Block.
Block and Code Disconnects
What is the difference between a disconnected block and a donated block? A block disconnect and a block donation are two different types of blocks being returned to a pool. A block disconnect refers to the return of an ‘Assigned’ Block. A block donation refers to the return of a ‘Retained’ block where you are the Code Holder and the code was not assigned to you by Pooling Administrator. Both types of blocks are returned to the pool using the block disconnect process in PAS.
Why is a reason required in the ‘Remarks’ field, when returning a block that is more than 10% contaminated?

Per Section 11.1.6 of the TBCOCAG: “In cases where the Thousands-Block Holder is Exiting the Market voluntarily and returns a Thousands-Block indicating that it is over 10% Contamination (101 TNs or more), the SP shall state in the “Remarks” field of the Part 1A that it is Exiting the Market.” 
“If the Thousands-Block being returned by the SP is over 10% contaminated and the SP does not indicate it is Exiting the Market, the PA shall deny the return.”

If I am returning a code and the blocks from that code, do I need to complete two separate requests? Yes, you will need to submit a code disconnect request and a block disconnect request for any Thousands-Blocks from that CO Code that were assigned to you by the PA.

What do I do if the NPA is in jeopardy and I participate in pooling in the NPA When NANPA declares jeopardy in an NPA this means that the forecasted and/or actual demand for NXX resources will exceed the known supply during the planning/implementation interval for relief.

Individual Block Requests
If you are participating in pooling and the NPA is in jeopardy and you are submitting an individual block request, the request will not be affected. It will be business as usual.

LRN, Pool Replenishment, or for a Dedicated Customer Code Request
Upon NANPA declaring jeopardy you must participate in the lottery until final jeopardy procedures are in place. Once final jeopardy procedures are in place and codes are set aside for pooling, you can submit a code request for an LRN, Pool Replenishment, or for a Dedicated Customer and these requests will not be affected; it will be business as usual.

If there are no codes set aside for pooling then you must participate in the lottery. When you have to participate in the lottery the application date on your Part 1 form submitted in PAS will be used by the NANPA code administrator to determine if your request falls within the appropriate lottery submission timeframes. The PA will not suspend your code request to “hold” it for the lottery. The PA will continue to process code requests as usual within our 7 calendar day processing timeframe.
