Area code 435 is a telephonearea code in theNorth American Numbering Plan (NANP) for most of theU.S. state ofUtah. Area code 435 was created in 1997 in a split ofarea code 801.
The numbering plan area excludes the region of theWasatch Front, which comprises theSalt Lake City,Ogden, andProvo metropolitan areas in northern Utah, and is served byarea codes 801 and 385.
The state of Utah was a single numbering plan area, witharea code 801, when theAmerican Telephone and Telegraph Company (AT&T) devised the first nationwidetelephone numbering plan in 1947.
On September 21, 1997, the 801 numbering plan area was geographically reduced to just a four-county area around and including Salt Lake City to provide more telephone numbers in that region. The rest of the state, much less populated, received the new area code 435. This numbering plan area includesBeaver,Brigham City,Castle Dale,Cedar City,Coalville,Duchesne,Fillmore,Heber City,Hurricane,Junction,Kanab,Loa,Logan,Manila,Manti,Moab,Monticello,Nephi,Park City,Panguitch,Parowan,Price,Randolph,Richfield,St. George,Tooele,Washington, andVernal.
The area code is also used for the Colorado City, AZ school district.
435 is one of the most thinly populated area codes in the nation; the great majority of Utah's population—and with it, most of its landlines and cell phones—is located along the Wasatch Front. As a result, 435 is nowhere near exhaustion. The projected exhaust date for 435 is 2041.[1]
