About Phone Validator

We share reliable and accurate public information about phone numbers. Our searches let you know what type of phone line any given phone number is – cell, landline, VOIP or toll-free. Individual lookups of our basic search are free. High volume, API and batch users can join and search fast with no ads, CAPTCHA or delays.

About our Free Search

Our free phone search uses the area code, prefix and first number of the last 4 digits to determine if a phone is a landline or cell based on its original assignment in the North American Numbering Plan.

Our free search does NOT check to see if the phone number has been ported from one phone company to another or from a landline to a cell phone. Phone porting or "portability" is the process in which the owner of a phone number can switch from one phone company to another and not lose his or her phone number.
