Ten-digit and seven-digit dialing in 364
According to NANPA's dialing-plan data, local calls within 364 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 at service providers discretion"
Who holds 364 exchanges
25 carriers hold the 72 central office codes assigned in 364. Onvoy Spectrum, LLC has the most, with 13 (18%). 72 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.
