Dialing 360 numbers

According to NANPA's dialing-plan data, local calls within 360 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 dialing permissible at service provider discretion"

Phone companies in area code 360

47 carriers hold the 786 central office codes assigned in 360. Qwest Corporation has the most, with 170 (22%). 553 of the codes (70%) 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.
