Phone Verification validates the ten digits of a U.S. telephone number and returns carrier information, plus the Location Routing Number (LRN) for telephone numbers administered by the North American Numbering Plan Administration (NANPA). LRN is a unique 10-digit number that represents a telephone switch through which multiple phone numbers are routed. The LRN enables Local Number Portability (LNP), which allows phone numbers to be ported to different carriers.
