Arkansas area codes — detailed data

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

This page expands the state overview with per-code operational data from NANPA: parent codes, projected exhaust dates, dialing patterns and relief status for all 4 Arkansas codes.

Aggregate footprint: the state's 4 geographic codes currently carry 2,001 active NXX prefixes over 413 rate-center anchorings, with 1,527 prefixes in thousands-block pooling. 4 of the codes serve territory inside FCC top-100 metropolitan statistical areas.

Lineage: 327 came out of 870 in 2024; 479 came out of 501 in 2002; 870 came out of 501 in 1997. The remaining code (501) dates back to the plan's early assignments.

Dialing plans: 3 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 479, projected to exhaust 1Q 2037.

Status: no Arkansas code is currently in jeopardy or active relief planning — capacity is adequate near-term per NANPA.
