Area code 317

Area code 317 serves Indiana, including Indianapolis, Carmel and Fishers (Eastern time). It has been in service since January 1, 1947 and shares its area with 463.

Numbers starting with 317 drew 2,446 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 590 complaints to the FCC since November 2023. The number on your screen can be faked, so a 317 number proves nothing about where a call came from.

Phone companies holding 317 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 62% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
