Find any 830- phone number in Texas

The 830 area code is used for the southwestern region of Texas and parts of the International Boundary. This area code is part of the North American Numbering Plan (NANP) system, a shared public telephone network that allows phones around the world to have the same standards. 830 area code is amongst the original 86 area codes that were created as NANP was introduced.

The 830 area code is geographically located within the Central Time Zone of the United States, which is in the Central Standard Time (CST). It encompasses following county-level administrative divisions of Texas including: Bexar, Blanco, Comal, Edwards, Guadalupe, Kerr, Kinney, Maverick, Real, Uvalde, Val Verde, and Zavala. It is one of the 26 area codes that were overlaid with a second area code as part of NANP's plan to preserve number availability and to prevent numbers from running out. 830 was later overlaid by the 737 area code, which created an overlay for the entire state of Texas. The 830 area code is used for both landline and wireless phone numbers, so it's important to note that both 830 and 737 should be dialed for any calls made within the state of Texas.
