Why Metro West Des Moines 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 West Des Moines now uses 515 and 641: same neighborhoods, ten-digit dialing, and every one of them covered by its own guide above.

The largest Iowa communities and the area codes that serve them. Every city links to its local AT&T internet page.
How Iowa Got Its Codes
Every Iowa 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.

|---|---|---|
| 1947 | 319 | One of the original area codes of 1947 |
| 1947 | 515 | One of the original area codes of 1947 |
| 1947 | 712 | One of the original area codes of 1947 |
| 2000 | 641 | Split from 515 |
| 2001 | 563 | Split from 319 |
