801 and 385 are area codes under the North American Numbering Plan covering the Wasatch Front in northern Utah. Specifically, area codes 801 and 385 cover Davis, Morgan, Salt Lake, Utah, and Weber counties. Some cities and towns included in this area code are Alta, Bountiful, Layton, Murray, Ogden, Orem, Provo, Salt Lake City, Sandy, South Jordan, Spanish Fork, Taylorsville, West Jordan, and West Valley City. This area code is in the Mountain Time Zone.
The main area code, 801, was one of the original area codes created in 1947, and served the entire state of Utah. On September 21, 1997, 801 was restricted to the Wasatch Front, while area code 435 was assigned to the counties outside of it. 385 is an overlay area code covering the same area as 801 which entered service on June 1, 2008.
The 1997 split was originally intended to be a long-term solution. However, the Wasatch Front is not only home to most of Utah's landlines, but most of its pagers, cell phones and fax machines as well. As a result, within only two years 801 was close to exhaustion once again. In 2000, the Public Service Commission of Utah (PSC) approved a split for 801 to take effect in 2001, in which Salt Lake County would retain the 801 area code and the rest of the Wasatch Front would be transferred to area code 385. Conservation measures allowed the repeated postponement of the area code split.
In July 2007, the PSC of Utah announced that the conservation measures would be exhausted in approximately June 2008, finally necessitating the implementation of the 385 area code. The same announcement stated that 385 would be implemented as an overlay, so that the Wasatch Front would be served by both area codes. 385 entered service on June 1, 2008. Permissive dialing began on that date, during which seven and ten-digit calls could be completed. Ten-digit dialing became mandatory along the Wasatch Front on June 1, 2009.
While the 801 area code is still the predominant area code in the region for land lines, 385 is being adopted quickly by wireless providers.
