The 518 area code is used for several counties of upstate New York. It originally covered the entire area of the state outside of the five boroughs of New York City, and was put into service in 1954. The 518 area code has since been split and has been further subdivided multiple times.
The North American Numbering Plan (NANP) is the national numbering system used for telephone services in the United States, Canada, and many Caribbean and Pacific Island nations. NANP consist of a 3-digit area code and a 7-digit telephone number. Every area code is designated to a certain geographic area within a given region. Area codes allow callers to identify which region they are dialing into. The 518 area code is just one of the many area codes designated to a certain geographic region within the NANP.
