Area codes serving Salt Lake City

Salt Lake City sits in Utah, part of the West region and the Mountain Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 385, 801.

The original code is 801 (in service since 1947). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

How to pick an area code for a new number

When you activate a new line in Salt Lake City, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 801), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.

Dialing in Salt Lake City
