The Telecommunications Act of 1996 mandated that consumers had the right to keep their telephone number when changing Service Providers. Today that process, known as Local Number Portability (LNP), seems simple and seamless. That’s because consumers don’t see all the complex behind-the-scenes work that makes it possible.
The system that makes LNP work for virtually all U.S. telephone numbers, including wireless, wireline and VoIP, is known as the Number Portability Administration Center (NPAC). Since the NPAC contains proprietary data from thousands of competing Service Providers, access to NPAC data is limited to specific, permitted uses and is available only to authorized NPAC users.
Local Number Portability (LNP), which was mandated as part of the Telecommunications Act of 1996, gives consumers the choice and convenience of keeping their wireline or wireless telephone number when switching from one Service Provider to another. Number portability was designed to increase competition among Service Providers, stimulate demand for telecommunication services, reduce prices for consumers and encourage technology innovation.
The history of LNP in the United States and its expansion from wireline to wireless to VoIP can be seen in a detailed timeline.
With the introduction of portability, telephone numbers were able to be switched between Service Providers. To ensure the correct routing of calls, a new way of determining the network address of the serving switch was needed. This led to the creation of the Location Routing Number (LRN), a unique 10-digit telephone number assigned to each switch, which makes LNP possible.
There are three reasons a telephone number might need to be ported and seven steps in the porting process.
