Area code 861

About area code 861

Area code 861 is a geographic area code in Illinois, in service since February 24, 2023, according to the North American Numbering Plan Administrator (NANPA). It is an overlay: 861 and 309 cover the same territory, so neighbors on the same street can have different area codes. It is in the Central time zone. The places with the most assigned exchanges include Peoria, Pekin, Rock Island, and Moline. By population, its largest named places are Peoria, Moline, Rock Island, and Pekin.

Where 861 numbers are local

861 holds 0.08% of the 8,977 central office codes assigned in Illinois, the 17th most of the state's 17 codes. 4 Census places could be matched to rate centers with 861 exchanges; the most populous are Peoria (112,000), Moline (42,442), Rock Island (36,434), and Pekin (31,266). Each place page lists the exact prefixes and carriers for that town.

Ten-digit and seven-digit dialing in 861

According to NANPA's dialing-plan data, local calls within 861 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. NANPA's dialing-plan note for this code reads: "1+10 digit permissible dialing at service providers discretion"

Who holds 861 exchanges

5 carriers hold the 7 central office codes assigned in 861. Exiant Communications LLC has the most, with 3 (43%). 7 of the codes (100%) 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.

Local calling areas in 861

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 861 has codes in 4 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.
