New and Upcoming Area Code Updates

Texas continues to grow, which means new phone numbers are always needed. The latest addition is area code 621, launched in January 2025 for the Houston metro. This overlay joins 281, 346, 713, and 832. The 945 overlay was also added to the Dallas-Fort Worth area a few years earlier.

Why Area Codes Change Over Time in Texas

As cities expand, new overlays are introduced to avoid running out of numbers. Instead of replacing old codes, Texas adds new ones so residents can keep their existing numbers while accommodating future growth.

How Texas Area Codes Are Organized

Texas follows the North American Numbering Plan (NANP), which divides regions into specific codes based on geography and population. Some cities share multiple codes because of overlays, while rural areas often cover larger zones with one code. For example, Austin’s 512 overlaps with 737, while El Paso still uses a single code, 915.

This structure ensures phone numbers remain available for new residents, businesses, and mobile lines statewide.
