XVerify’s phone verification service allows you to validate landlines and cellphone numbers within the U.S. or Canada. You can validate phone numbers in real time across any channel, or via automated batches. During the validation process we first check to make sure the area code is accurate and that there is no formatting issues. Then we run the check against the telecom database records to ensure it is a legitimate line. If you need an advanced level of verification on the phone numbers you acquire, we recommend you take a look at our Phone Confirm
solutions to enable dual authentication.
