Numbering plan areas and area codes of Texas with numbering plan area 409 highlighted.

Area code 409 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of Texas. The numbering plan area comprises the Beaumont and Galveston areas. It was created on March 19, 1983, in an area code split of area code 713, the first since 619 split from 714 four months earlier. Initially, it consisted of a horseshoe-shaped area that almost completely surrounded Houston, but in 2000 it was divided into three sections. Area code 409 was retained by the eastern segment, while the central portion, centered on Nacogdoches, received area code 936 and the western portion centered on Bryan–College Station, was assigned area code 979.
