Area coe 585 is a state of New York (USA) telephone area code and was created in 2002 for use in the city of Rochester, New York and surrounding areas. Previously 716 was used for the area now in 585. Area Code 716 was shared with Buffalo and much of Western New York, until numbers in that area code became scarce. A few towns such as East Aurora, Arcade, and Alden have the 585 area code as well as the 716 code as an overlay.
