The area code 680 is located in Auburn, New York.
Area code 680 serves Auburn, New York, as an overlay to the long-standing 315 area code in Central New York. This overlay covers the same footprint as 315, so it includes Auburn and nearby communities across the Finger Lakes, Mohawk Valley, and the North Country. Auburn sits in Cayuga County, near Owasco Lake, and is known for the Harriet Tubman National Historical Park and the Seward House Museum—landmarks you can reach using 315/680 phone numbers. The overlay ensures steady number availability without changing existing 315 numbers, while keeping local calling areas the same.
Major cities and communities in the 315/680 region include:
“According to the New York State Public Service Commission, mandatory 10‑digit dialing in the 315/680 region began on February 11, 2017, and new 680 numbers were first assigned on March 11, 2017.” — New York State Public Service Commission
Area code 315 dates back to 1947 as one of the original North American area codes, and 680 was added as an overlay to meet demand for new phone numbers. If you live, work, or travel in Auburn and Central New York, you’ll see both 315 and 680 on caller ID, but they reach the same geographic area. Because of the overlay, ten-digit dialing (area code + number) is required for all local calls. This setup keeps long-time 315 numbers in place while allowing new 680 phone numbers for homes, businesses, and mobile lines across Auburn and its neighboring cities.
