Houston area code 713 split in 1996, when area code 281 was added.
The boundaries between the two area codes were erased in 1999 when area code 832
was added. You or your business could be assigned any of the three area codes when
you move or add additional lines.
Cities and prefixes for each area code have been provided by the North American Numbering
Plan Administration (NANPA), which oversees the area code number assignment system. This information
will change as new prefixes are added or returned.
Prefix information will be updated periodically from the NANPA database of
Texas prefixes in use in each area code. All prefixes listed on the Texas Area Codes site reflect NANPA numbering data through June, 2009. Because of the way
telephone data is assembled, some cities may not be on the list. If you feel any city is not
listed or is listed incorrectly, please send the city, prefix, and area code to
areacode@puc.state.tx.us and it will be researched and added if NANPA’s information coincides. Any questions or comments about the Texas
Area Codes section of the PUC site should also be sent to this address.
