About the 631 area code
Area code 631 covers a group of New York communities that includes Brentwood, Commack, Huntington Station, Centereach, and West Babylon, all observing Eastern time.
Created in 1999 from the territory of area code 516, the code later gained a partner when 934 arrived as an overlay across the same area. The two now issue numbers jointly, and local dialing there runs to the full ten digits.
Dialing note: 631 is part of an overlay complex with 934, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
