The North American Numbering Plan (NANP) divides the territories of its members into geographic numbering plan areas (NPAs). Each NPA is identified by one or more numbering plan area codes (NPA codes, or area codes), consisting of three digits that are prefixed to each local telephone number having seven digits.
Area code 605 is the telephone area code in the North American Numbering Plan for the entire U.S. state of South Dakota.

The U.S. Coast Guard (USCG) uses a set of two-letter prefixes for vessel numbers; [18] 39 states and the District of Columbia have the same USPS and USCG abbreviations. USCG prefixes have also been established for five outlying territories; all are the same as the USPS abbreviations except the Mariana Islands.

For example, the Atlantic City, New Jersey, telephone number 4-5876 was converted to AT4-5876 during the 1950s. Complete replacement of existing prefixes was necessary in the case of conflicts with another office in the state.
