Phone Verification

Determine whether a phone number is wireless or a landline - in real time. Even if the phone number has been ported between service providers, Phone Verification will return the latest information.

Phone Verification validates the ten digits of a U.S. telephone number and returns carrier information as well as 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.

The benefits of using the Phone Verification API include:


 * Determine if a phone number is valid
 * Remove dashes, parenthesis and spaces
 * Receive latest SMTP email string data
 * Define time zone to restrict calling times
 * Validate wireless vs landline data for compliance
