Texas Area Codes

About Area Codes in Texas

Texas (TX) is the The Lone Star State, located in the South region of the United States. With a 2023 population of 30,503,301 residents, Texas is served by 28 active area codes. The state capital is Austin and the largest city is Houston.Texas's official motto is "Friendship."

Area code assignments in Texas follow the North American Numbering Plan (NANP), which has been in effect since 1947. As the state's population and demand for phone numbers grew — driven by the rise of cell phones, fax machines, pagers, and VoIP lines — regulators either split existing area codes geographically or added overlay codes that share the same territory. That's why Texas now has 28 codes: 210, 214, 254, 281, 325, 346, 361, 409, 430, 432, 469, 512, 682, 713, 726, 737, 806, 817, 830, 832, 903, 915, 936, 940, 945, 956, 972, 979.

When you receive a call from a Texas number, the area code tells you only where the number was originally assigned. Because of Local Number Portability (LNP), which took effect in 2003, callers can keep their phone numbers even when moving across state lines. So while a 210 number was once assigned in Texas, the person calling you could be anywhere in the US today.

Time zones in Texas

Texas observes the Central and Mountain time zones. Daylight Saving Time is observed from the second Sunday in March through the first Sunday in November, when clocks shift forward by one hour. When you call a Texas number from outside the state, double-check the local time above each area code detail page to avoid calling at unreasonable hours.

Phone number format in Texas

All Texas phone numbers follow the standard 10-digit NANP format: (NPA) NXX-XXXX. For local calls within Texas, you typically need to dial the full 10-digit number — even for calls within the same area code — because of mandatory 10-digit dialing imposed by the FCC for areas with overlay codes (most of Texas's territory). For long-distance calls within the NANP, dial 1 + area code + 7-digit number.

Will Texas get more area codes?

As Texas's population and number demand grow, NANPA may assign additional overlay codes.

The AreaCodeCentral team tracks these announcements and updates the directory within 24 hours of any new code activation.
