New 363 area code for Nassau starts next week

Nassau County’s new 363 area code may be assigned to new phone lines beginning next week, according to the state Department of Public Service. 

The PSC approved the new area code in Jan. 2022 to accommodate future economic growth and to satisfy growing consumer demand. The new 363 area code will be superimposed over the same geographical area as the existing 516 area code that serves all of Nassau. 

The area code overlay requires consumers to continue to dial 10 digits for local calls (area code + 7-digit telephone number) in the 516/363 area or 1 + 10 digits for calls to other area code regions. Customers in the 516 area code have already been completing local calls by dialing 10 digits since the July 16, 2022, national implementation of the 988 Suicide and Crisis Lifeline, the PSC says. 

Current telephone numbers, including current area code, will not change and neither will the price of a call. Numbers in the 363 area code will not be available for assignment until remaining numbers in the 516 area code are exhausted, according to the PSC.
