By population, its largest named places are Salt Lake City, Provo, Lehi, Ogden, and Eagle Mountain.

Dialing 801 numbers

According to NANPA's dialing-plan data, local calls within 801 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number.

Phone companies in area code 801

24 carriers hold the 783 central office codes assigned in 801. Qwest Corporation has the most, with 326 (42%). 387 of the codes (49%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Rate centers and towns in 801

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 801 has codes in 20 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.
