Access U.S. number portability data from the only authorized source
Our nation relies on connectivity. Companies require access to data regarding our nation’s nearly 1 billion telephone numbers to perform vital day-to-day operations, such as routing, rating, billing and telecommunication network maintenance. With millions of businesses and consumers switching Service Providers each year, accessing the most recent number portability data is critical.
The Number Portability Administration Center (NPAC) is the authoritative source for phone number porting information for virtually all U.S. telephone numbers, including wireless, wireline and Voice over IP Providers (VoIP). NPAC data can be accessed for very specific uses and only qualified businesses and organizations are authorized to receive the data or derived data.

Recognizing Authorized PTRS Users
Companies that are providing or receiving NPAC Data must be registered with the Number Portability Administration Center (NPAC).
Providers of NPAC Data: To ensure your company is complying with your contractual obligations surrounding NPAC Data, you are required to certify that you are only providing NPAC Data to other registered PTRS Users.
As the Local Number Portability Administrator (LNPA), iconectiv now offers an official Provider of Telecommunications Related Services (PTRS) Badge to registered PTRS Users so they can demonstrate that they are authorized to provide or receive NPAC Data. The badge serves as a visual indicator that the organization is registered with the NPAC. Businesses should look for the PTRS Badge on websites before providing NPAC Data to others. Confirming the presence of the PTRS Badge helps organizations assure they are providing NPAC Data to registered PTRS Users only.
Recipients of NPAC Data: We encourage you to also look for the PTRS Badge from any companies that you are receiving NPAC Data from to ensure data is obtained from a trusted, authorized source.
