How calls are dialed in 601

According to NANPA's dialing-plan data, local calls within 601 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.

Carriers with 601 numbers

34 carriers hold the 783 central office codes assigned in 601. Bellsouth Telecomm INC d/b/a South Central Bell Tel has the most, with 241 (31%). 458 of the codes (58%) 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.
