Connect with Houston's energy executives, Texas Medical Center's healthcare community, and the Port of Houston's logistics teams with a 713 virtual number. Instant activation — compliance-ready call recording included.
Area code 713 is Houston's core — the Energy Capital of the World, a port handling 10% of US trade, and the Texas Medical Center, the world's largest medical complex. A 713 number puts your business at the heart of the 4th-largest US metro.
From Houston to El Paso 713 covers the South Central region of Texas.
713 covers downtown Houston — the global headquarters of ExxonMobil, Chevron, ConocoPhillips, and Shell. No other area code carries more weight in the energy industry.
The world's largest medical complex employs 106,000 people and treats 10M patients annually. A 713 number is essential for any business in this healthcare ecosystem.
The busiest US port by cargo tonnage lies within 713's coverage. Maritime, freight, and import/export businesses depend on this code's local credibility.
713 is the original Houston area code — assigned in 1947 and still the number the city's boardrooms and business culture identify as truly local.
Every 713 number delivers fourteen professional features for Houston's energy capital — call recording for petrochemical compliance, multi-line IVR for the Texas Medical Center, and instant SMS for the Port of Houston.
