Why Choose a 363 Area Code?
The 363 area code was launched in 2023 as an overlay to the existing 516 area code. Both area codes cover Nassau County, located on western Long Island just outside of New York City.
From the bustling towns of Hempstead and Freeport to coastal communities like Long Beach, a 363 number gives your business a local voice in one of New York's most affluent and high-demand regions.
