801 overlay codes and dialing
The 801 territory is covered by an overlay of 2 area codes: 385, 801. All of them serve the same geographic area, and the original code is 801. Because more than one code covers the same ground, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes.
History of the 801 area code
801 is one of the original area codes assigned in 1947, when AT&T and Bell Laboratories created the North American Numbering Plan and divided the country into the first 86 numbering plan areas. It has served the Salt Lake City area ever since, with 385 later added as an overlay to supply more numbers.
Is 801 a scam or spam risk?
801 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 801 number on your screen is no guarantee the caller is in Salt Lake City, UT or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
