Welcome to NeuStar’s NPAC Customer Center

This Web site provides instructions to entities interested in becoming an “NPAC User” in order to receive or create NPAC data.  Even if an entity intends to obtain NPAC data from a third party, rather than from the NPAC itself, it is necessary to become an authorized “NPAC User.”  There is no charge to become an “NPAC User” but there are charges for most methods of access to the NPAC.

Law Enforcement Agencies wishing to have access to the NPAC IVR system should not register to become an "NPAC User" on this Web site. Please go to the Law Enforcement/911 PIN Registration website at http://www.npac.com/the-npac/access/law-enforcement-agencies-psaps and complete the online registration form.

Note: To become an NPAC User in the Canadian region, it is first necessary to become a member of the Canadian LNP Consortium, Inc. To become a member of the Consortium, please contact Marian Hearn, Project Executive at 613-287-0225 extension 102.

If you have any questions about becoming an NPAC User or the application process, please contact us by clicking on the “Contact Us ” link.

All Applicants must provide evidence of (i) Workers Compensation insurance for all states that require coverage and (ii) commercial general liability insurance (including contractual liability and products liability coverage) with combined single limits of at least $2,000,000 in the general aggregate for bodily injury and property damage.

  2. A Certificate of Public Convenience and Necessity (for wireline carriers) or a Radio License (for wireless carriers)

If you have applied for access to the NPAC rather than merely to become authorized to receive NPAC data from a third party, the e-mail notice will provide further instructions for completing the registration process.

An Applicant’s access to any of the regional NPACs is conditioned upon execution of an NPAC/SMS User Agreement.  Upon such execution of an NPAC/SMS User Agreement, Applicant is considered a “User” of the regional NPAC for which the NPAC/SMS User Agreement is executed.  Subject to the master agreements between Neustar, as the administrator of the regional NPACs, and the North American Portability Management LLC, with responsibility (recognized by the U.S. Federal Communications Commission) for implementing telephone number portability in the U.S., the NPAC/SMS User Agreement grants Users limited rights concerning and imposes certain restrictions with respect to access to and use of data Neustar maintains in the various, regional NPACs.  The following is a summary of such rights and restrictions.

User Data - All data provided by NPAC Users to the regional NPACs is User Data.  Data that is merely identical to User Data, but is not obtained from the NPAC (either directly or indirectly), is not User Data.  User Data may be provided only to an NPAC User; however, an entity that is not a User may receive data derived from User Data. 

Permitted Use - User Data, or data derived from User Data, may be used only for the purpose of routing, rating, or billing of calls, or performing network maintenance in connection with the provision of telecommunications services, provided however that the activity is impacted by porting or pooling.  No other use of User Data is permitted.    An entity that merely relays data between NPAC Users and the NPAC/SMS is not subject to the Permitted Use requirement, but is responsible to assure that recipients of the relayed User Data are themselves NPAC Users.  Finally, commercial exploitation of User Data is expressly prohibited, as it is not a Permitted Use.  On behalf of the service providers whose data resides in the NPAC, the North American Portability Management LLC has clarified the meaning of the terms comprising Permitted Use and commercial exploitation of User Data:

Routing - The phrase “routing of calls” means transporting of calls.

Rating - The phrase “rating of calls" means determining the applicable charge for calls.

Billing - The phrase “billing of calls" means rendering a bill for calls.

Calls - The term “calls” refers to the transmission of information (e.g., video, pictures, audio [voice, music], messages, text, data, or combinations of these) by use of a telephone number (NPA-NXX-XXXX), which may include the transmission of signaling messages or the transmission of provisioning data associated with information sessions, subscribers, and network equipment and devices (e.g., discovery, parameter negotiation, establishment, connection, maintenance, disconnection, presence, location, authentication, billing, and usage).  Internet addresses and naming protocols (URLs, URIs, IP addresses, etc.) also are considered call routing information, so long as these items are associated with a telephone number.

Network Maintenance - The phrase “network...maintenance in connection with providing telecommunications services” means any activity or process undertaken to ensure that operational, administrative, compliance, repair, and other functions of the User, including without limitation those concerning systems, databases used for telecommunications purposes, or networks, can be performed in an efficient, timely, or accurate manner.  Network Maintenance includes, by way of illustration and not limitation, the following:

  • Using the activation broadcast to determine when systems (such as LIDB, CNAM, Voice Mailbox, PSTN or other switching device, etc.) may be updated to reflect loss or gain of a customer.
  • Using the User Data to determine current SP to verify that a telephone number can be ported from a current SP before programming a system to anticipate port-in of the number.
  • Using the User Data to determine a TN’s current SP to determine whether to take a trouble report or to comply with a legal request.
  • Using the User Data to determine appropriate call routing translations.
  • Using the User Data to administer a telephone number assignment system.
  • Using the User Data to administer an inter-carrier billing system.
  • Using the User Data to allow operator services system to determine whether a call may be alternate billed (i.e., to identify serving carrier to determine whether contract is in place).
  • Using the User Data to administer databases used for network maintenance purposes.

Commercial Exploitation of User Data - This prohibited use refers to the use of User Data, or data derived from User Data, for the purpose of marketing telecommunications services to consumers of telecommunications services or identifying those consumers to obtain or retain them as customers.  Merely deriving an economic benefit from a service that uses or discloses User Data, or data derived from User Data, does not constitute commercial exploitation.

Service Provider - The term “Service Provider” includes any entity to which PSTN numbering resources are assigned by the NANPA or the national Pooling Administrator.  For example, a "class 1" stand-alone VoIP provider is a Service Provider.

Telecommunications Services - The term “telecommunications services” includes "telecommunications-related services." 


Step 3 - The NPAC Region User Agreement

An NPAC Region User Agreement is required for each NPAC region for which you request data or NPAC access.  (The U.S.New NPAC User Application indicates which areas are served by each NPAC region.)

The User Agreement(s) will be available under your account after your application is approved. The completed User Agreement also must be accepted by NeuStar before you can become an authorized NPAC User.

  • Log on to your account.  This requires the User ID and Password we provided you when we accepted your NDA.
  • Click on the “NPAC Regional User Agreement” section of the site
  • A User Agreement is required for each region in which you wish to become an NPAC User.
  • When you have completed a User Agreement, click on “submit.”
  • After your User Agreements are processed by Customer Connectivity Services, you will receive an e-mail indication the approval or rejection of your User Agreements.

This concludes the steps you need to take to become an NPAC User.

Connectivity to the NPAC

You will receive your login information for the NPAC Secure Site once your User Agreement has been approved and processed. If you require access to the NPAC, as opposed to needing to become an NPAC User merely to be authorized to receive NPAC, data from a third party your SPID will need to be activated in the NPAC. A Customer Project Manager will work with you to walk you through the steps required.
