History of Area Code 713
Area code 713 was established in 1947 as one of the original North American Numbering Plan area codes. It originally covered a much larger part of southeastern Texas than the present Houston-focused region.
In 1983, area code 409 was created from part of 713. In 1996, area code 281 was created in a split that moved many suburban Houston exchanges out of 713. Area code 832 became an overlay in 1999, and area code 346 became an additional overlay in 2014. These changes added numbering capacity without requiring existing 713 customers to change their numbers.
