Iowa area codes: all 5 codes and where they ring

All Iowa area codes

Figures come from NANPA: the area code report, the rate-centre report and the exhaust projections, all in the file of 11/01/2026. This is not an official NANPA site.

How Iowa area codes began

1. 1947: 319 was among the original 1947 codes, serving Ainsworth, Alburnett and Allison.
2. 1947: 515 was among the original 1947 codes, serving Adel, Alden and Algona.
3. 1947: 712 was among the original 1947 codes, serving Akron, Albert City and Alta.
4. 2000: 641 was created by a split from 515, covering Ackley, Adair and Afton.
5. 2001: 563 was created by a split from 319, covering Alpha, Andrew and Arlington.

Dialling within Iowa

Local calls inside 319 and 515 use 10-digit dialling. Calls that go long distance use 1 + 10-digit dialling.

Local calls inside 712, 641 and 563 use 7-digit dialling. Calls that go long distance use 1 + 10-digit dialling.

Of the 378 US area codes now in service, just 54 still allow 7-digit local calls.
