History of Area Code 713

Area code 713 was established in 1947 as one of the original North American area codes. At first, it covered a large part of southeastern Texas, not just Houston.

As telephone demand grew, the 713 service area became smaller through splits. Area code 409 split from 713 in 1983, and area code 281 split from 713 in 1996. In 1999, area code 832 was added as an overlay to the Houston area, and in 2014, area code 346 was added as another overlay. These changes reflected steady population growth and rising demand for new telephone numbers in Houston.
