How to Verify Phone Numbers

If you have a phone number and want to verify that it is valid, you can look it up and find out its status, or you can check it by calling the number with your phone. An online phone validator can tell you under what name a phone number is listed, whether it is for a landline or a cell phone, and what phone company services it.
