The history of Utah area codes

Before 435 opened in 1997, 801 served Utah by itself for 50 years.

1947: Among the original area codes from 1947 was 801, which covered Alta, American Fork and Bountiful.
1997: 435 was separated from 801 to serve Altamont, Antimony and Apple Valley.
2009: 385 became an overlay for 801, covering the same area.

Making calls in Utah

A local call in area 801 or area 385 needs 10-digit dialling. For long-distance calls, dial 1 + the 10-digit number.

In 435, local calls are placed with 7 digits, while long-distance calls use 1 + the 10-digit number.

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