The area code 830 is located in Medina, Texas.
Area code 830 serves Medina, Texas, and a wide stretch of the Texas Hill Country and Southwest Texas. Centered along the Medina River in Bandera County, Medina sits amid rolling hills, ranchland, and scenic drives that define this region. The 830 area code links rural communities, small cities, and key border towns, making it vital for local homes, schools, and businesses. It reaches from the hills north and west of San Antonio to the Rio Grande, all within the Central Time Zone.
Established in 1997, 830 was created in a split from 210 to handle growing demand for phone numbers around San Antonio and the Hill Country. It effectively forms a ring around the San Antonio metro, covering communities along I‑10, US‑90, US‑83, and US‑281. This makes 830 common on caller IDs for Hill Country calls as well as international gateway cities on the border. “Area code 830 was created in 1997 from area code 210.” — North American Numbering Plan Administrator (NANPA)

The region is known for clear rivers and state parks, including the Guadalupe River, Medina River, Garner State Park, Amistad Reservoir near Del Rio, and Enchanted Rock near Fredericksburg. In and around Medina, orchards and hilltops shape local life; Medina is widely recognized for its apple growing and hosts seasonal events tied to the harvest. Because 830 covers both frontier border crossings and fast-growing Hill Country towns, it supports a mix of landline and mobile phone numbers across many counties, including Bandera, Comal, Kerr, Guadalupe, Val Verde, Maverick, Uvalde, Gillespie, and Kendall. If a phone number starts with 830, it most likely traces back to this Hill Country and border region of Texas.
