463 Area Code
Area codes 317 and 463 are the primary telephone prefixes serving Indianapolis and its surrounding communities. These codes span neighborhoods across the city and have become a defining part of Indianapolis’s modern communication network.
The 317 area code has deep roots in the city’s history. First introduced in 1947 as part of the North American Numbering Plan, it was one of the original area codes in the United States and once covered much of central Indiana. As the region’s population and business activity grew, the 463 overlay was added in 2016 to provide additional numbers without forcing residents or companies to change their existing ones.
Today, both codes are widely used for cell phones and landlines throughout Indianapolis—from downtown and Fountain Square to Broad Ripple and the nearby suburbs. Major carriers such as AT&T, T-Mobile, and Verizon all operate under these prefixes, supporting communication for both households and thriving local businesses.
The 317 and 463 area codes are more than just digits; they represent the city’s growth, connectivity, and strong community identity. Whether it’s a personal call, a business meeting, or an emergency, these numbers help keep Indianapolis connected every day.
