The area code 765 is located in Kokomo, Indiana.
Area code 765 serves Kokomo, Indiana and a wide stretch of central and east-central Indiana, surrounding the Indianapolis metro. It was introduced in 1997 when 317 was split, creating a dedicated code for communities outside the capital region. The footprint runs from the Lafayette–West Lafayette area in the west to Richmond near the Ohio line in the east, connecting college towns, manufacturing hubs, and historic downtowns. If you’re seeing a 765 phone number, it most likely ties to this central Indiana corridor rather than the 317/463 Indianapolis core.
Key cities and communities covered by area code 765 include:
You’ll find 765 numbers along major travel routes like I-65 and I-69, linking campuses, factories, and small towns across the region. The code supports both mobile and landline phone numbers, making it common for businesses, universities, and residents in Kokomo and nearby cities. It’s a practical identifier for central Indiana callers and a quick hint that the call likely comes from outside the Indianapolis 317/463 area.
“Mandatory 10-digit dialing began on Oct. 24, 2021 in affected area codes due to the national 988 lifeline.” — FCC
That change includes area code 765, so always dial the full 10 digits when calling local numbers. Whether you’re reaching a Kokomo manufacturer, a Purdue department, or a Muncie small business, a 765 number signals a strong connection to central Indiana.
