Why Houston and Dallas stack so many codes
Texas’s two giant metros stack codes deeper than anywhere outside California. Houston dials five on one map: the original 713 (1947), 281, 832, 346 and 2025’s 621. Dallas dials four: the original 214, 972, 469 and 945, with Fort Worth’s 817/682 next door. Same rates, same 10-digit dialing; only the year a number was issued differs.
Texas’s newest area code: 621
Texas’s newest code went live in January 2025: area code 621 overlays the Houston metro alongside 713, 281, 832 and 346. Nothing changed for existing numbers: same phones, same rates, no renumbering. New Houston lines simply began drawing 621, with the new code projected to cover the metro’s growth for roughly a decade.

How Texas’s codes work
How Texas splits
Houston runs deepest: 713, 281, 832, 346 and the new 621 share one territory. Dallas stacks 214, 469, 972 and 945, San Antonio pairs 210 with 726, and Austin 512 with 737; West Texas runs wide on 432, 806 and 915.
Overlays share one territory
An overlay serves the exact same area as the code it joins: new numbers, same map. Houston carries five (713, 281, 832, 346 and 621), and 430, 469, 682, 726, 737, 945 and 972 overlay their regions the same way.
Houston's newest overlay, 621, went live in January 2025.
