Minnesota area codes — detailed data

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

Working detail for Minnesota's 8 area codes: history, capacity forecasts and dialing plans, straight from NANPA's NPA database.

Aggregate footprint: the state's 8 geographic codes currently carry 3,745 active NXX prefixes over 639 rate-center anchorings, with 2,374 prefixes in thousands-block pooling. 6 of the codes serve territory inside FCC top-100 metropolitan statistical areas.

Lineage: 320 came out of 612 in 1996; 651 came out of 612 in 1998; 763 came out of 612 in 2000; 924 came out of 507 in 2024; 952 came out of 612 in 2000. The remaining codes (218, 507, 612) date back to the plan's early assignments.

Dialing plans: 4 codes use plain ten-digit local dialing (10D); 4 still allow 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 218, projected to exhaust 3Q 2036.

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