Kansas area codes — detailed data
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 Kansas codes.
Aggregate footprint: the state's 4 geographic codes currently carry 2,300 active NXX prefixes over 574 rate-center anchorings, with 1,733 prefixes in thousands-block pooling. 4 of the codes serve territory inside FCC top-100 metropolitan statistical areas.
Lineage: 620 came out of 316 in 2001; 785 came out of 913 in 1997. The remaining codes (316, 913) date back to the plan's early assignments.
Dialing plans: 2 codes use plain ten-digit local dialing (10D); 2 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 785, projected to exhaust 2Q 2032.
Status: no Kansas code is currently in jeopardy or active relief planning — capacity is adequate near-term per NANPA.
