Florida 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 23 Florida codes.
Aggregate footprint: the state's 23 geographic codes currently carry 11,094 active NXX prefixes over 374 rate-center anchorings, with 7,879 prefixes in thousands-block pooling. 21 of the codes serve territory inside FCC top-100 metropolitan statistical areas.
Lineage: 239 came out of 941 in 2002; 321 came out of 407 in 1999; 324 came out of 904 in 2024; 352 came out of 904 in 1995; 386 came out of 904 in 2001; 407 came out of 305 in 1988; 448 came out of 850 in 2021; 561 came out of 407 in 1996; 645 came out of 305 in 2023; 656 came out of 813 in 2022; 689 came out of 407 in 2019; 727 came out of 813 in 1998; 728 came out of 561 in 2023; 754 came out of 954 in 2001; 772 came out of 561 in 2002; 786 came out of 305 in 1998; 850 came out of 904 in 1997; 863 came out of 941 in 1999; 941 came out of 813 in 1995; 954 came out of 305 in 1995. The remaining codes (305, 813, 904) date back to the plan's early assignments.
Dialing plans: 18 codes use plain ten-digit local dialing (10D); 5 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 352, projected to exhaust 3Q 2030.
Status: no Florida code is currently in jeopardy or active relief planning — capacity is adequate near-term per NANPA.
