How calls are dialed in 915

According to NANPA's dialing-plan data, local calls within 915 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 provider discretion."

Carriers with 915 numbers

45 carriers hold the 367 central office codes assigned in 915. Southwestern Bell has the most, with 105 (29%). 270 of the codes (74%) 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.

Where 915 numbers are rated

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 915 has codes in 11 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.
