1947
801 first assigned
801 came first, in 1947
801 was Utah's original area code, assigned in 1947. The newest, 385, arrived in 2008. Each of the 3 codes below maps to its own part of the state, so the code you pick shows which region you serve.
01 — Utah at a Glance
Utah, by the numbers.
Utah got area code 801 in 1947, and it was the state's only code for exactly 50 years.
On September 21, 1997, Utah split: 801 pulled back to the Wasatch Front (Salt Lake City, Ogden, Provo), while the rest of the state became 435.
Continued Wasatch Front growth exhausted 801 again. Instead of splitting further, overlay 385 launched in 2008 on the same territory, with mandatory 10-digit dialing following in 2009.
Utah's three codes still trace that history: 801 and 385 share the urban core, and 435 covers the rest of the state.
Did you know?
Area code 435 covers roughly 97 percent of Utah's land area but only a fraction of its population, since the Wasatch Front's 801 and 385 hold most residents in a narrow urban corridor.

Calling Utah: what to know
Time zones, dialing rules and area code status, with the sources we checked.
Time zone
Utah is on Mountain Time and observes daylight saving time.
Dialing
Ten-digit dialing has been required for local calls in the Wasatch Front region of 801 and 385 since March 1, 2009, according to the Deseret News and the Associated Press. Callers dial 1 only for long distance. Utah was not on the FCC's 2021 list of area codes forced to ten digits.
Area code status
385 is an overlay on 801. After the Public Service Commission approved a split in 2000, number pooling delayed it for years, and in July 2007 the commission announced an overlay instead. 435, created in 1997 for the rest of the state, was not part of the overlay. We found no announced relief plan.
Good to know
- 801 and 385 serve the Wasatch Front in north-central Utah: Davis, Morgan, Salt Lake, Utah and Weber counties, including Salt Lake City, Ogden, Provo and Orem.
- 435 covers most of Utah outside the Wasatch Front and surrounds 801. Communities include St. George, Cedar City, Logan, Park City, Moab and Vernal.
- The Deseret News reported at the 2009 switch that existing 801 customers kept their numbers, so a single home could have two area codes.
