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.
• Be signed by an authorized representative of the service provider.

The LOA should be faxed to 925-363-7685 or emailed to poolingsupport@neustar.biz.
If I forgot my password for PAS, how can I obtain a new password? You will need to send an email to poolingsupport@neustar.biz 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 contact with you.
If I forgot my user id for PAS, how can I obtain my user id? You will need to send an email to poolingsupport@neustar.biz 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 contact with you.
If I receive an error message stating my account is inactive/disabled what do I need to do in order to have it activated/enabled? Your PAS account may be disabled for the following reasons:
• 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.
• PAS users will be disabled after three unsuccessful login attempts.

You will need to send an email to poolingsupport@neustar.biz 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. A pooling representative will contact with 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
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, Netscape), please adjust the settings to always allow pop-ups from the Number Pooling website (www.nationalpooling.com). Failure to do so could prevent you from receiving the session timeout messages from the Pooling Administration System (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 warning five (5) minutes prior to the session expiring. By clicking on the OK button on the pop-up blocker, 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, Netscape), please adjust its settings to always allow pop-ups from the Number Pooling website (www.nationalpooling.com). Failure to do so could prevent you from receiving the session timeout messages from the Pooling Administration System (PAS).
Why am I not receiving an email notification once the PA issues a Part 3? 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 neustar.biz email addresses (ex: poolingsupport@neustar.biz). Failure to do so could prevent you from receiving email notifications sent from your pooling administrator and/or emails from the Pooling Administration System (PAS).
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 go to Reports also located in the tools frame and select Part 1A Report, Part 3 Report and Donation Reports to review the status of requests as well.
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 PAS work items are not automatically removed after a period of time. You are the only one who can modify or delete your PAS work items.
Why are there both PAS-generated emails and PAS work items for the same items? PAS is simply 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 from that code at any time? 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”, enter the state, NPA, rate center and select the “Assigned Blocks” radio button, then click “Continue”. You can also download a 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”, enter the state, NPA, rate center and select the “Available Blocks” radio button, then click “Continue”.
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”, enter the state, NPA, rate center and select the “Retained Blocks” radio button, then click “Continue”.
Is there a way I can pull the blocks available, blocks assigned and blocks retained reports greater than one NPA at a time? 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”.
Am I able to print reports? Yes, you can use the Download button to download reports into Excel then print the report from Excel.
How far do the reports go back to? You have the ability to produce 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? Go to www.nationalpooling.com. From the home page, select Reports located in the tools frame, then select NPA/Rate Center Reports, choose a State and NPA from the drop-down boxes in the center of the page. This will bring up a Rate Center Reports page with a description of the various pooling statuses found on the report (M, M*, red M, O and X). From the reports page, select Rate Center Files and open the Adobe file (found at the bottom of the page). This will bring up a list of rate centers with their pooling status along with a legend with definitions of each of the statuses.
How do I opt into pooling? Contact the Number Pooling Customer Support desk at 1-866-638-7665 or poolingsupport@neustar.biz.
If I choose to participate in thousands-block number pooling in a voluntary rate center outside of the top 100 MSA, can I withdraw from pooling in that voluntary rate center at any time? No, you cannot withdraw from pooling in the voluntary rate center once you’ve submitted a forecast; a donation or a thousands-block has been assigned to you.
How do I determine if a thousands-block is contaminated or not? One 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”, 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 is contaminated. If there is a “N” then the thousands-block is pristine.

We also 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 1-888-NPAC-HEL(P) or 1-888-672-2435.
Thousands-Block Donations
What happens if I donated a thousands-block in error? Section 7.2.7 of the TBPAG describes what steps can be taken to retrieve a thousands-block donated in error, “Subsequent to the Block Donation date, the SP may have a need to retrieve a block they had previously donated to the pool. Likely reasons could be errors in reported block contamination levels, assignments made after block protection, customer request, etc. Via email with the PA, the SP may exchange its own blocks. If this cannot be accommodated, then the SP must apply for the block via a Part 1A. In the case where the SP needs one of its own blocks back but cannot meet the MTE/utilization, the PA may agree to hold the block until requirements are met or the SP may seek appropriate regulatory intervention.”
What steps must I take prior to donating a thousands-block?

Section 4.1 d) of the TBPAG outlines what steps the code holder must perform prior to donating a thousands-block:

4.1 d) “confirm, prior to donating the thousands-block to the industry inventory pool, that:

1) all unavailable TNs within contaminated thousands-blocks have been intra- service provider ported;
2) the associated NPA/NXX is currently available for call routing, is flagged as 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);
3) the NXX-assigned switch is currently LNP-capable and will process terminating traffic appropriately; and
4) interconnection facilities have been established between the NXX-assigned switch and other interconnecting networks.”

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

See also section 7.2.7 of the Thousands-Block Number (NXX-X) Pooling Administration Guidelines (TBPAG) for additional information regarding donations.
What do I need to do after my donations have been processed and accepted by the PA? Per Section 7.2.7 of the TBPAG:
  • For any donations from a non-pooled NXX, the AOCN is responsible for entering its specified routing and rating information for those retained thousands-blocks. The retained thousands-block will not appear in the LERG Routing Guide until the AOCN has performed this task.


    • This means that for any block that have been retained, your AOCN needs to go into BIRRDS and create the NXD-X records. For example if you donate NPA-NXX-1,2 and 3, your AOCN would need to create NXD-X 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 6.0 of the TBPAG directs carriers 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 Thousands-Block Forecast Report (Appendix 1)."

    Section 6.1.1 of the TBPAG further advises, "NRUF forecast data needs to be supplemented in areas where thousands-block pooling has been implemented, and all thousands-block number pooling SPs shall provide a Thousands-Block Forecast Report (Appendix 1), on a semi-annual basis, by rate area to the PA in addition to the NRUF."
    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? For the Pooling Forecast, 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 areas. If a full NXX 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 FTP. Additional information and FTP Requirements is located under Documents on the pooling website. For additional questions or information regarding FTP you may contact Jeremiah Jenkins via email at jeremiah.jenkins@neustar.biz or via phone at 571-434-5523.
    Block Reservations
    When can a block reservation be requested? A SP may request to reserve a block(s) when a state waiver request has been submitted to the appropriate regulatory authority.
    What do I need to provide that shows that a state waiver has been submitted? The SP shall provide a statement of certification including 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 request to the PA via fax or email.
    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 block reservation
    • The block has been reserved 6 months with no follow up assignment or cancellation request. The block reservation will be automatically cancelled and the block returned to the pool one day after the 6 month reservation period has passed.
    Part 1A and Part 1 Forms
    What is the standard thousands-block effective date? According to section 8.2.4 of the Thousands-Block Number (NXX-X) Pooling Administration Guidelines (TBPAG), the standard block effective date is 31 calendar days from date of application plus the 2-day NPAC update period in order to allow for NPAC processing and downloads to occur.
    What is an expedited effective date and how do I indicate this on my Part 1A form? An expedited effective date is a date earlier than the standard thousands-block effective date (31 calendar days). To request an expedited effective date, select “Yes” for “Request Expedited Treatment” in section 1.3 of the Part 1A and modify the date in the “Requested Block Effective Date” field.

    Section 8.6 c) of the Thousands-Block Number (NXX-X) Pooling Administration Guidelines (TBPAG) outlines the expedited effective date process and timeframes:

    c) The PA will process the application if the request meets the criteria for the allocation of the thousands-block(s) and will make every effort to process the application in fewer than the current maximum 7-calendar days. The PA will expedite such requests when it can do so without failing to meet its 7-calendar day allocation interval for other SPs. The PA will determine the minimum Effective Date for an expedited request based upon the following considerations:

    1) If the thousands-block applicant is the LERG Assignee, and no NPAC notification is required, the Effective Date must be at least nine calendar days after the Part 3 Allocation Date. This allows for the PA and AOCN to update BIRRDS for LERG Routing Guide daily updates. The AOCN must agree to perform the BIRRDS update in two calendar days rather than the standard five calendar days.

    If the thousands-block allocated requires NPAC notification, the Effective Date will be no earlier than eight business days after allocation: three business days to build the thousand block ownership table and five business days for a potential first 'port' notification.
     
    When I submit a request for a full NXX in PAS do I need to send anything to the PA? If the code request is an initial request, you will need to send your certification or license and proof of facilities readiness to the PA. The TBPAG sections 4.3.1.1 and 4.3.1.2 lists the acceptable proof of facilities readiness and certification.
    When making a change to an NXX at the 10K level for a code that is in pooling, what forms do I need to send manually to the PA? You will be able to submit a code modification through the PAS. If you need to send supporting documentation of any kind to the PA, you will need to email or fax the documentation to the PA.. If the same updates need to be made at the thousands-blocks level for this NXX, please submit one Part 1A modification for each thousands-block in PAS.
    When returning an NXX at the 10K level for a code that is in pooling, what forms do I need to send manually to the PA? You will be able to submit a Code disconnect through PAS. No manual forms need to be submitted.

    As a reminder per section 2.2 of the COCAG Appendix C document, “The SP returning an NXX code will coordinate with NANPA to ensure that the code is not removed from the LERG Routing Guide as an active code until the Part 3 with the effective date of the disconnect is received. This is to prevent an adverse effect on ported-out customers.”
    What should I do if I notice an error on a request that I just submitted? If you made an error on a request that was just submitted, you can modify that request in PAS as long as the PA has not opened that 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 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, you can hit 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-workers saved requests? Yes, as long as you have in your profile the same OCN, State, and NPA of the user who originally saved the request.
    Can I submit a block transfer through PAS? Yes, block transfers can be done through PAS as an ‘Inter OCN’ Block Modification request.
    State Waivers
    Does PAS issue a denial for a State Waiver? Yes, if you do not meet MTE, PAS will provide a radio button that you may select ‘Need to Request a State Waiver’. If this button is selected PAS will process an automatic denial so you can proceed in requesting a state waiver from the appropriate commission.
    Once you submit a request for an automatic denial for state waiver, do you have to completely re-enter a new request after you receive the approval from a state commission to get the desired blocks? 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 send in the approval of a state waiver from the state the same day as you make your request in PAS.
    While my request for a state waiver was pending with the state commission, I met the months to exhaust and utilization requirements, so I went ahead and requested the thousands-block. After receiving the thousands-block, I was granted the state waiver. Am I still obligated to request another thousands-block or do I ignore the granted state waiver? No, you are not obligated to request another block, and you cannot use the original state waiver to obtain an additional thousands-block, since your situation has changed.
    Part 1B Form
    Who do I contact if my Part 1B is rejected? Any questions related to the rejection or approval of your Part 1B can be directed to the NPAC help desk at 1-888-NPAC-HEL(P) or 1-888-672-2435. The HD will open a ticket for the NPAC Pooling Team. 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. If the block request is time critical, an expedite can be requested in PAS when the request is resubmitted.
    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 box as "Yes", the NPAC will activate the block range. By marking the activate box as "No", it will be the responsibility of the SP to activate the block range. You may contact the NPAC help desk at 1-888-672-2435 for further details.
    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. Numbering personnel 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. Entering incorrect DPC and SSN information can also result in rejection of your request and require resubmission of the request through PAS. See Question # 1 for additional information regarding rejected Part 1B block requests.
    What happens if I enter the wrong LRN on the Part 1B forms? Entering incorrect LRN information is service affecting. Numbering personnel 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. Entering incorrect LRN information can also result in rejection of your request and require resubmission of the request through PAS. See Question # 1 for additional information regarding rejected Part 1B block requests.
    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. You should also mark NPAC Activate Block Range = No in conjunction with checking "For Information Only".
    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 blocks have been assigned to you via a Part 3, then you can submit a block modification in PAS and select ‘Part 1B’ as the type of change, then indicate “Yes” for ‘Will block X of X be activated by NPAC’.
    Months-to-Exhaust Worksheet
    When do I need to complete the Months-to-Exhaust Worksheet? When you request additional thousands-blocks for growth 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 a 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 Local Exchange Routing Guide (LERG) within the preceding 90 days of reporting utilization levels may be excluded from the utilization calculation.”
    Part 4 Form
    Can I reply to the ‘Confirmation of Block Activation (Part 4) Reminder’ email with my Part 4 form? No, you must submit your Part 4 directly into PAS, which updates your Part 4 record immediately. You can contact the Number Pooling Customer Support desk at 1-866-638-7665 or poolingsupport@neustar.biz if you experience any issues with your Part 4 submission.
    How many customers do you have to have on a block in order to submit a Part 4? You must have at least one customer on the block in order to submit a Part 4 to acknowledge that the block is in service. “In service” is defined in the TBPAG as a code or block for which local routing information has been input to the LERG Routing Guide and the carrier has begun to activate numbers within the NXX ode or NXX-X block to end users (FCC 00-104 ¶240)
    If I request an effective date change for my new block assignment, will my Part 4 due date change? Only if you request an earlier effective date than what was previously assigned to you. Then your Part 4 due date will be based on the new effective date.
    How do I extend my Part 4 due date? To extend a Part 4 due date the user must contact the appropriate state commission or the FCC (if the state does not handle the reclamation process) for an extension of a Part 4 due date.
    Part 5 Form
    What is the purpose of the Part 5 form? As a LERG assignee, 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 LERG assignee, and the block holder that the thousands-block has been removed from the NPAC. The LERG assignee 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
    When should a block disconnect be submitted? If the block was assigned by the PA, or if you have a retained block but you are not the LERG Assignee (as a result of a block transfer). You can also refer to the Block Report to determine if the block is in an ‘Assigned’ or ‘Retained’ status.
    What is the difference between a disconnected block and a donated block? A block disconnect and a block donation are two different processes used to return blocks to a pool, where they are made available to be reassigned to another carrier. A block disconnect is the method used to return an ‘Assigned’ Block. A block donation is the method used to return a ‘Retained’ block where you are the LERG Assignee.
    Why is a reason required in the ‘Remarks’ field, when returning a block that is more than 10% contaminated? To assist the PA in determining if a new block holder needs to be found. If no valid reason is provided, the request may be denied.
    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 and a block disconnect for any blocks that were assigned to you by the PA from that code.
