Nebraska area codes — detailed data

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

Working detail for Nebraska's 3 area codes: history, capacity forecasts and dialing plans, straight from NANPA's NPA database.

Aggregate footprint: the state's 3 geographic codes currently carry 1,503 active NXX prefixes over 552 rate-center anchorings, with 1,109 prefixes in thousands-block pooling. 2 of the codes serve territory inside FCC top-100 metropolitan statistical areas.

Lineage: 531 came out of 402 in 2011. The remaining codes (308, 402) date back to the plan's early assignments.

Dialing plans: 2 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 402 (complex 402/531), projected to exhaust 1Q 2040.

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