Area code 605
 |
North American Area code 605 is the telephone area code serving the entire state of South Dakota, and is one of the area codes that was created in 1947. It is also one of a gradually decreasing number of single-state, single LATA, single area code areas. (North Dakota uses only the Area code 701, but is split into two LATAs, one of which includes Minnesota.)
