How calls are dialed in 803

According to NANPA's dialing-plan data, local calls within 803 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 each service provider discretion"

Carriers with 803 numbers

53 carriers hold the 784 central office codes assigned in 803. Bellsouth Telecomm INC d/b/a Southern Bell Tel & Tel has the most, with 173 (22%). 536 of the codes (68%) 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.
