About 713 Area Code
Area code 713 serves Houston and the surrounding metropolitan region. Established in October 1947 as one of the original 86 area codes in the North American Numbering Plan, 713 initially covered all of southeastern Texas before being reduced to focus on the Houston metro area. Today, 713 operates as part of a five-code overlay system with 281, 832, 346 and 621 serving the same geographic region across Harris, Fort Bend, Brazoria, Galveston and surrounding counties. The code supports local voice and SMS numbers used by energy companies, medical institutions, aerospace firms, logistics providers and thousands of businesses throughout the fourth-largest city in the United States.
Houston has earned the title of Energy Capital of the World, hosting more than 5,000 energy-related firms including major oil and gas companies, renewable energy innovators and petrochemical manufacturers. The region is also home to the Texas Medical Center (the largest medical complex in the world), NASA's Johnson Space Center, and the Port of Houston (one of the busiest ports in America). Local businesses use 713 numbers for client relations, appointment scheduling, dispatch coordination, sales outreach and customer support. A 713 number carries cultural significance in Houston and signals authentic local presence, often yielding higher answer rates than toll-free or out-of-state numbers because it matches community expectations.
FoneSwift lists live 713 inventory and capabilities on this page. Search numbers to see which support Voice, SMS and MMS. Area code availability changes as Houston continues rapid growth. If a 713 number isn't immediately available, overlay codes like 281, 832 or 346 serve the same geographic region and deliver identical local presence for Houston-area campaigns, so consider all overlay options when searching for the right number.
If you're targeting Houston or metro customers, display numbers in both local and E.164 formats (e.g., (713) 555-1234 and +1 713 555 1234) and register messaging traffic for A2P campaigns if you plan bulk SMS. For porting, consult our porting guide. Many Houston businesses keep the same number for years to maintain continuity with clients and customers who recognize that local line as part of the city's proud identity. Houston celebrates 713 Day each July 13, reflecting the deep cultural connection residents feel to this iconic area code.

How Does Local 713 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages.

The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (713): directs the call to the Houston / Texas region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
