LRN Contacts

Sources for the NPA-NXX of a Telephone Number's LRN

When Local Number Portability (LNP) was mandated in the United States, the Location Routing Number (LRN) was introduced to support call routing. The LRN is a unique 10-digit number that serves as the network address and includes the area code (NPA) and central office code (NXX) for a telephone number. While NPAC User Data is restricted* to authorized NPAC users only, the NPA-NXX associated with an LRN is available to non NPAC users.

The following list of companies are willing to provide this information to non NPAC users:
