Texas area codes

Texas has roughly 30+ active area codes — among the most of any U.S. state — reflecting its large population and several major metros. The Dallas–Fort Worth, Houston, Austin and San Antonio metros each carry multiple overlaid codes. The newest is 621, a Houston-region overlay in service since early 2025.

Every code opens its profile — codes with a full write-up show their place; the rest show live numbering data while their detailed profile is added.

High-confidence but possibly incomplete: the authoritative NANPA enumeration was unreachable, so this ~29-code list (from secondary sources) may miss 1–2 newer overlays. 621 is the newest (in service early 2025).
