Texas is currently using twenty-six area codes. Texas is utilizing five area code overlay plans, often called overlay complexes. Texas recently implemented the new area code 346 as an overlay of area codes 832, 713 and 281.

Texas originally had four area codes, 214, 512, 713, and 915 when the numbering system was established in 1947. By 1953, just six years later, Texas experienced sufficient growth in population and telephone use to need an additional area code. To meet this increase in demand area code 214 was split in 1953 to form area code 817. In 1957 area codes 817 and 915 were split to form area code 806. Throughout the 1960s and the 1970s no new area codes were introduced. One new area code, 409 was put into service in 1982. In the 1990s eleven area codes were introduced. Another six area codes were introduced between 2000-2003.
