A Brief History of Area Code 518
Area code 518 was one of the original area codes assigned to New York State in 1947, serving the northeastern corner of the state ever since. For decades a single code was sufficient for the largely suburban and rural region, but rising demand for numbers led to the introduction of the 838 overlay in 2017. The overlay covers the same territory as 518 and brought mandatory 10-digit dialing to the Capital Region.

Numbers in the 518 area code operate on Eastern Time (ET). The region observes Daylight Saving Time, switching from EST (UTC−5) to EDT (UTC−4) between March and November.
