LRN Enhancements

Written on Jul 19, 2020.

We are happy to announce several enhancements to our LRN product.

What is an LRN?
Local Routing Number (LRN) is an identification for a telephone switch for the purpose of routing telephone calls through the PSTN (Public Switched Telephone Network) in the United States. It's existence signifies that a number has been ported, and it is the heart of an LCR engine to ensure that calls are routed using the lowest rate.


1) In addition to XML and TEXT output we are now also providing a JSON.

2) In addition to LRN data previously provided (LRN,OCN,LATA,City,Rate Center, State, Jurisdiction, Local, LEC and LECTYPE) we are now also providing our users the SPID and the Activation date of the port.

3) Support for HTTP/HTTPs, SIP and ENUM as query options.
