Dialing 270 numbers
According to NANPA's dialing-plan data, local calls within 270 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"
Phone companies in area code 270
45 carriers hold the 769 central office codes assigned in 270. Bellsouth Telecomm INC d/b/a South Central Bell Tel has the most, with 152 (20%). 600 of the codes (78%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself.
