About Area Code 405
Area code 405 is a North American Numbering Plan (NANP) area code that has been in service since 1947. It is administered by NANPA on behalf of the FCC and serves the Oklahoma region anchored on Oklahoma City.
405 now shares its territory with an overlay code (572). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 405 are portable: a person who moved away from Oklahoma City may still carry a 405 mobile number on their device. If you receive an unexpected call from a 405 number, run it through the reverse lookup tool above for the most accurate, free identification.
