FL
United States geographic area code, in service since 1988-04-16. Part of the 321/407/689 overlay complex — ten-digit dialing required.
Split from 305. Created 561. Created 321. Created 689. Overlaid with 689 .
Prefix-level assignment does not equal number-level exhaustion; thousands-block pooling extends capacity. First assignment on record 2001-02-12, most recent 2025-06-10.
Area codes serve rate-center geographies, not municipal boundaries. “FL” identifies the jurisdiction, not an exact city footprint.
