History of Area Code 430

Area code 430 was established on February 15, 2003. The North American Numbering Plan added it as an overlay for area code 903, which had been created in 1990 from a split of area code 214.

Area code 430 did not replace 903. It was added because the 903 region needed more telephone numbers as cities and communities across East Texas continued to grow. Because 430 is an overlay, both 430 and 903 serve the same geographic area.
