The new Nassau county 363 area code is set to launch in January
Phone service carriers can begin assigning 363 to the start of new phone numbers issued in Nassau County at some point after the area code goes into service Jan. 20.
For more than 70 years, 516 has been the only area code assigned to Nassau County. Now, the public has a new set of numbers to learn: 363.
The new area code became necessary once it was determined that all 10-digit phone numbers in the 516 area code would soon be depleted.
