LRN Lookup Tool

Open

 For conversational traffic utilizing the Standard, Enterprise, Premium, T38, or Customizable termination rate decks, VoIP Innovations will bill outbound calls based off the LRN (Local Routing Number) of the telephone number that is called. For short duration traffic using the Dialer termination rate deck, VoIP Innovations bills calls off the destination number itself (DNIS).
The LRN is simply used to identify which switch a telephone number is associated with. Local Routing Number was introduced to facilitate Local Number Portability (LNP) in that the routing of telephone numbers did not need radically changed when numbers moved between wireline and wireless services. Previously, the NPA-NXX of a telephone number was used to identify the state and rate center where the number was originally assigned, as well as the service provider and carrier type (wireless or wireline). The LRN was introduced to serve as the network address of the telephone switch which services the number. The LRN therefore replaces the need to identify rate center, state, service provider, and carrier type and only identifies the switch the number is associated with. If a number has never been ported, it will not have an LRN but will route based on the NPA-NXX of the number. Numbers that have been ported and consequently have an LRN, route based off the NPA-NXX of the LRN.

Even though VoIP Innovations is a third party providing LRN information to you, it is necessary for you to FIRST have the user agreement before using this tool. As per Neustar's User Agreement: "There is no charge to become an NPAC User." A link is provided to their site from the LRN Lookup

If you would like to view the LRN of any telephone number VoIP Innovations provides an LRN
Lookup Tool located in the Back Office from the Term Tab. Simply click the Term Tab -> Tools -> LRN Lookup Tool. Please note the format for this tool is 10-digit numbers ONLY. Do not use spaces, dashes, etc. Once you have entered your desired query, you will get the resulting LRN in full 10-digit format. Keep in mind that our rate decks are comprised of rates for the NPA-NXX of the LRN. Once you have the LRN result, you can query the rate for a specific rate deck. Simply select the desired rate deck from the drop-down list and click the 'Get LRN Rate' button to see both the Interstate and Intrastate rates. After receiving the rate results, you can choose a different rate deck and run the query again to compare prices if desired.
