About Area Code 251
Area code 251 is a North American Numbering Plan (NANP) area code that has been in service since 2001. It is administered by NANPA on behalf of the FCC and serves the Alabama region anchored on Mobile.
251 is currently a single-coverage geographic area code with no overlays. This means a 7-digit number in this area code is unique within its rate centers, though best-practice is always to dial the full 10-digit number when contacting a 251 line.
Mobile numbers in 251 are portable: a person who moved away from Mobile may still carry a 251 mobile number on their device. If you receive an unexpected call from a 251 number, run it through the reverse lookup tool above for the most accurate, free identification.
