Area code 607 is shaded red; the rest of the state of New York is blue.
North American area code 607 is a state of New York telephone area code servicing parts of its Southern Tier (which borders Pennsylvania). It was created in 1954 by combining the southern portion of 315 and the eastern portion of 716. Initially, in the late 1940s, area codes with a middle digit of "0" (x0x-xxx-xxxx) were assigned only to jurisdictions covering an entire state. Along with 507 in Minnesota and 606 in Kentucky, 607 was among the first such area codes to be added to a jurisdiction.
