New York 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 23 New York codes.

Aggregate footprint: the state's 23 geographic codes currently carry 11,974 active NXX prefixes over 1,103 rate-center anchorings, with 8,665 prefixes in thousands-block pooling. 21 of the codes serve territory inside FCC top-100 metropolitan statistical areas.

Lineage: 329 came out of 845 in 2023; 332 came out of 212 in 2017; 347 came out of 718 in 1999; 363 came out of 516 in 2023; 465 came out of 718 in 2026; 516 came out of 914 in 1951; 585 came out of 716 in 2001; 624 came out of 716 in 2023; 631 came out of 516 in 1999; 646 came out of 212 in 1999; 680 came out of 315 in 2017; 718 came out of 212 in 1984; 838 came out of 518 in 2017; 845 came out of 914 in 2000; 917 came out of 212 in 1992; 929 came out of 347 in 2011; 934 came out of 631 in 2016. The remaining codes (212, 315, 518, 607, 716, 914) date back to the plan's early assignments.

Dialing plans: 14 codes use plain ten-digit local dialing (10D); 8 require 1+ ten digits; 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 347 (complex 347/718/917/929), projected to exhaust 3Q 2027.

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