Area code 585 serves western New York, including Rochester and surrounding suburbs such as Geneseo and Batavia. Created in 2001 from a split with area code 716, it covers a region known for its historic contributions to industry, education, and the arts. Rochester, home to major universities and tech companies, is a regional hub. Ten-digit dialing is mandatory due to overlay code 364, introduced in 2023. Area code 585 is emblematic of western New York’s blend of innovation, cultural heritage, and revitalization efforts in an evolving economic landscape.
