Why Metro Oklahoma City Has 2 Area Codes
When a region uses more numbers than one code can hold, new codes are overlaid on the same territory rather than forcing anyone to change numbers. Metro Oklahoma City now uses 405 and 572: same neighborhoods, ten-digit dialing, and every one of them covered by its own guide above.
Oklahoma Area Codes by City
The largest Oklahoma communities and the area codes that serve them. Every city links to its local AT&T internet page.
How Oklahoma Got Its Codes
Every Oklahoma area code, in the order it entered service. Splits carved new regions; added codes overlay existing ones, which is why ten-digit dialing is standard.
| In service | Code | How it arrived |
|---|---|---|
| 1947 | 405 | One of the original area codes of 1947 |
| 1953 | 918 | Original assignment for its region |
| 1997 | 580 | Split from 405 |
| 2011 | 539 | Added to the 918 region |
| 2021 | 572 | Added to the 405 region |
