409

409 is the area code which comprises most of Galveston County in Texas. (The Northern part of Galveston county usually has a 281 area code.) 409 also includes the Beaumont area which is lesser known.

Houston people usually think of 409 as the area code for the Galveston area not the Beaumont area. 409 is more widely known for the Galveston area.
