About Oklahoma Area Codes

Oklahoma is served by 5 area codes within the North American Numbering Plan (NANP). The area codes are distributed across different cities and regions of the state to accommodate the demand for phone numbers.

All Oklahoma phone numbers use the international country code +1, followed by the three-digit area code and a seven-digit local number, for a total of 11 digits when dialing internationally.

Some areas of Oklahoma have overlay area codes, meaning two or more area codes serve the same geographic area. In these regions, 10-digit dialing is mandatory for all local calls.
