Cellular Back Door Number Finder
Wireless Phone Number Finder

To identify the cellular carrier that supplies service to a phone customer and their location, visit these sites and enter the Area Code and Prefix (NPA-NXX) of the wireless number. See Note*





*NOTE: A few areas have numbers assigned to different carriers based on the 7th digit. Also, some numbers may no longer conform to these records after having been "ported" through Local Number Portability. In those cases, only the original assignment is shown. Some old cellular company names are shown as that is how they are still listed in the administrator's records.
