The area code 283 is located in Cincinnati, Ohio.
Area code 283 serves Cincinnati, Ohio, as an overlay to the long-standing 513 area code in southwest Ohio. It began service on April 28, 2023, allowing new phone numbers in the Cincinnati region to be assigned with 283 while existing 513 numbers stayed the same. With this overlay, 10-digit dialing is required for local calls within the 283/513 area. The coverage mirrors 513 and centers on Cincinnati and its nearby suburbs and townships.
Major communities and landmarks in the 283/513 area include:
Cincinnati sits on the Ohio River and is known for the Cincinnati Zoo & Botanical Garden and big-league action at Great American Ball Park and Paycor Stadium. The 283 overlay remains on the Ohio side; nearby Northern Kentucky uses area code 859. Because 283 simply expands number supply for the same footprint as 513, calling and texting work the same as before—just dial 10 digits. Fun fact: 513 is one of Ohio’s original area codes from 1947, and 283 is its modern companion for a growing region with deep Midwestern roots.
