Georgia area codes — detailed data

NANPA NPA database, current as of July 28, 2026.

Full numbering detail for every active Georgia area code: lineage (which code it split from), NANPA exhaust projections, dialing plans and jeopardy status. This is the working data behind the overview page.

Aggregate footprint: the state's 10 geographic codes currently carry 6,212 active NXX prefixes over 576 rate-center anchorings, with 4,385 prefixes in thousands-block pooling. 9 of the codes serve territory inside FCC top-100 metropolitan statistical areas.

Lineage: 229 came out of 912 in 2000; 470 came out of 678 in 2010; 478 came out of 912 in 2000; 678 came out of 470 in 1998; 706 came out of 404 in 1992; 762 came out of 706 in 2006; 770 came out of 404 in 1995; 943 came out of 470 in 2022. The remaining codes (404, 912) date back to the plan's early assignments.

Dialing plans: 9 codes use plain ten-digit local dialing (10D); 1 still allows seven-digit local calls. Overlay territories always dial ten digits; the 2021 988-hotline transition moved most others to ten digits as well.

The tightest capacity in the state is 912, projected to exhaust 2Q 2028.

Status: 1 with relief planning in progress — details in the table.
