What does the Phone Verify API do?
Phone Verify validates the ten digits of a U.S. telephone number and returns carrier information as well as the Location Routing Number (LRN). 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. Note that toll-free numbers do not return LRN information.
