Gain access to America’s only portability registry
The Number Portability Administration Center/Service Management System (NPAC/SMS) is the system that supports the implementation of Local Number Portability (LNP) and is used to facilitate number porting in the United States. Once a ported number is activated, real-time network downloads are sent from the NPAC to all Local Service Management Systems (LSMS).
Reasons a telephone number may need to be ported
When a telephone number moves from the current Service Provider to a new Service Provider.
When a telephone number moves from one switch to another within the same telecommunications Service Provider's network.
When a telephone number moves to a new Service Provider in blocks of 1,000 to create an inventory of unassigned telephone numbers.
- Inter-carrier or competitive porting
- Intra-carrier porting
- Number pooling
How to facilitate porting
To facilitate porting, a Service Provider sends porting information, called “Subscription Version” information, to the NPAC. Service providers choose their access method based on business need. A Subscription Version can be entered or modified via a non-merchanized web-based Low Tech Interface (LTI), mechanized Service Order Administration (SOA) system, request via the NPAC Help Desk, or via a Service Bureau. Once a ported number is activated, real-time network downloads are sent from the NPAC to all Local Service Management Systems (LSMS).
