Geographic Regions and Area Codes

Area Code 518 serves a broad area in eastern upstate New York, encompassing 17 counties and over 1,200 ZIP Code areas. The major cities within this area code include Albany, Schenectady, Troy, Saratoga Springs, and Plattsburgh. Additionally, it covers regions such as the Upper Hudson Valley counties, Greene and Columbia counties, and parts of northern Dutchess County.

Area Code 838 overlays the same geographic region, implemented in 2017 following New York Public Service Commission approval due to projected number exhaustion. The overlay was necessary as the region experienced "unprecedented demand for central office codes" driven by business expansion and population growth. Both area codes are part of the North American Numbering Plan (NANP) and are crucial for phone routing in the region.

Current FCC data indicates the 518 area code shows 49.1% assignment rates with 46.6% availability, demonstrating moderate utilization pressure relative to other regions. This data reflects the area's robust business activity and continued telecommunications demand.
