Utah has 3 active area codes as of 2026, covering the state through a mix of original 1947 assignments, geographic splits, and modern overlays. This guide walks through the full list, which regions each code serves, the order they came online, and where new codes are most likely to land next.
The Short Answer
Utah currently has 3 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
By population, Utah ranks #30 nationally with roughly 3,503,000 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.
The Full List of Utah Area Codes
The active area codes serving Utah are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.
- 385 — Wasatch Front (Salt Lake City, Ogden, Provo) (overlay of 801)
- 435 — All of Utah outside the Wasatch Front (St. George, Logan, Cedar City, Moab, Park City)
- 801 — Wasatch Front (Salt Lake City, Ogden, Provo)
How Utah’s Area Codes Grew Over Time
Utah received its first area code, 801, when the North American Numbering Plan launched in 1947. That single code initially covered the entire state, and subsequent splits and overlays narrowed it over the decades that followed.

- 1997 — 435 split off from 801 on September 21, 1997, taking over the rest of Utah and leaving 801 as an enclave serving only the Wasatch Front.
- 2008 — 385 entered service on June 1, 2008 as an overlay of 801 across the Wasatch Front, with ten-digit dialing becoming mandatory on June 1, 2009.
What’s Next for Utah Area Codes
Utah’s three area codes give the state ample numbering capacity for the near term. The 2008 overlay of 385 onto 801 added a full numbering plan area to the fast-growing Wasatch Front, and NANPA’s recent NPA exhaust analyses do not list any Utah numbering plan area on the near-term relief schedule. The most likely future pressure point is the 385/801 overlay serving the Salt Lake City metro as Utah’s population continues to grow, but no additional relief is projected before the late 2020s at the earliest.
Frequently Asked Questions
How many area codes does Utah have right now?
Utah has 3 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Utah?
801 is the oldest active area code in Utah, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Utah?
The most recent area code addition to Utah was 385, activated in 2008. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Utah need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
How many area codes does Utah have?
Utah has three active area codes: 801 and 385, which overlay the Wasatch Front around Salt Lake City, Ogden, and Provo, and 435, which covers the rest of the state.
What area code is Salt Lake City?
Salt Lake City and the wider Wasatch Front are served by two overlaid area codes, 801 and 385. 801 is the original code dating to 1947, and 385 was added as an overlay in 2008. New lines in the metro may be assigned either code, so ten-digit dialing is required for local calls.
What area code is St. George, Utah?
St. George uses area code 435, which serves all of Utah outside the Wasatch Front, including Logan, Cedar City, Moab, and Park City. The 435 code split off from 801 in 1997.
Why does the Wasatch Front have two area codes?
The Wasatch Front kept the original 801 code after the 1997 split that created 435, but rapid growth in landlines, cell phones, and pagers exhausted the available numbers within a few years. Rather than split the region again, regulators added 385 as an overlay in 2008 so existing 801 holders could keep their numbers while new numbers draw from 385.
