Location Routing Number service

Local Number Portability, mandated by the FCC in 1996, enables consumers to keep their telephone numbers when changing service providers.

Location Number Portability relies on the Location Routing Number (LRN), a ten-digit number that looks like a telephone number. A LRN is assigned to a ported telephone number and is used to properly route the call by acting as a network address.

Service providers must use the LRN to properly route all ported calls. LRN lookup is commonly referred to as an LRN dip. If there were no LRN dip service available, nearly 50% of all calls could not be completed correctly.

TransNexus LRN dip service

Other dip services have complicated pricing that can change based on your volume. With TransNexus, you get unlimited dips and a daily LRN download, so you can correctly route every call, every time.

And should you decide it’s time for least cost routing or SIP Analytics for telecom toll fraud and robocall prevention, these services are easily enabled in our ClearIP and NexOSS software products and can be performed at the same time.

Please note that our LRN dip service is available in the U.S. only.
