Service Providers can load their own LRNs via the LTI, Mechanized SOA Interface or by contacting the NPAC Helpdesk at 1-888-672-2435. Please note that contacting the NPAC Helpdesk may result in a billable charge.

Yes, you are required to have the LRN loaded before a Pool Block can be scheduled.

Part 1B’s must be submitted within the Pooling Administration System (PAS), which can be found by accessing the National Number Pool Administration website at https://www.nationalpooling.com/.

Additional information can be found by clicking on the ‘New To Pooling’ link and the PAS User Guides under the ‘Documents’ link. If you are still uncertain how to proceed, you can contact the National Pooling Administration Support for assistance at 1-866-638-7665.

Send an email to the Pooling Administrator and request that the block activity take place early (note the requested date in the email).  The Pooling Administrator will forward the email to the NPAC Pooling team.

You can either submit a Part 1B Modification form through PAS or contact the NPAC Help Desk at 1-866-672-2435 to request a modification.

This error occurs if a Service Provider checks the “For Information Only” field in any combination with the NPAC Activate Block Range field on the Part 1B form or if the block is being allocated back to the Code Holder on the donating switch. If you incorrectly entered either of these, you will need to submit a Part 1B modification within PAS to modify the incorrect field.  If you are the Code Holder, you must submit the NPAC .

You should mark the Part 1B form as “For Information Only"

The following Destination Point Codes (DPC) can be used in the NPAC.   If you need DPC values loaded to your SPID in an NPAC region, you will need to contact the NPAC Help Desk at 1-888-672-2435.

• LIDB: Line information database

• CNAM: Caller name delivery

• CLASS: Customer local area signaling services

• ISVM: Inter-switch voice messaging

• WSMSC: Wireless short message service center

You can call the National Pooling Administration Support at 1-866-638-7665.

As the Code Holder, your block routes through the LERG and would not need to be activated in the NPAC.  If you want the block to route to a different switch the block can be activated to a LRN in the NPAC.   

BIRRDS and the NPAC SMS are two separate systems. The Code needs to be put into the NPAC SMS for porting reasons.  If the code is not built in the NPAC, other service providers will not be able to port any telephone numbers from that Code.  Also, Service Providers who are assigned blocks under that Code will not be able to activate their blocks until the Code is entered.

There are two options to handle the Block Transfers to avoid a loss of service:

1. Port the active TNs prior to the transfer and once the transfer has been completed, you can delete the ports so they snap back to you.
2. Perform a hot cut on the effective date, where the block will be disconnected and then scheduled for 5 minutes later.  By doing this method, your active customers may lose service for approximately 5 minutes, but it could be up to one hour if there are any issues found while processing. A hot cut done outside of business hours will incur Dedicated Support charges.

Since the block was “in red” when you requested the block in PAS, you have stated that you agree and understand that there is a chance your effective date will not be met.  For this reason, the only options you have are to contact the Code Holder directly to ask them to load the code or to contact your Pooling Administrator and request another block (if there are any available) in that rate center.

The Pooling team is available during regular business hours, 8am -6pm, Eastern Time, Monday through Friday.  If you have an emergency request that cannot wait until the next business day, you may contact the NPAC Help Desk at 1-866-638-7665 and have a ticket opened up.  The Pooling team on-call representative will be paged out and will call you back promptly to handle your request.
