MINEOLA, N.Y. (WCBS 880) — Nassau County is officially getting a new area code.
In addition to the already existing 516, Nassau County’s soon-to-be area code, 363, is set to be implemented during the second quarter of 2023, according to the New York State Public Service Commission.

The announcement Monday came months after a petition was filed by SomosGov, Inc., following the revelation that the current 516 area code will “exhaust its supply of available numbers in the third quarter of 2023.”
Beginning late next year, phone customers in Nassau County who are requesting new service, an additional phone line or a move in the location of their service, may be assigned a number in the new 363 area code.
Existing customers with a 516 area code in Nassau County will not be affected, according to the commission.
“Customers will retain their current telephone numbers, and 10-digit dialing for local calls will continue,” the commission said in a release.
“The overlay area code will be assigned to newly issued telephone numbers in Nassau County once all existing 516 telephone numbers are exhausted, and will apply to all telephone numbers, regardless of service type. The new area code is projected to provide telephone number relief in Nassau County for approximately 49 years.”
With the addition of the new number, Long Island will officially have four area codes: 516 and 363 in Nassau County, and 631 and 934 in Suffolk County.
