Area code 640

Area code 640 serves New Jersey, including Atlantic City, Lawrenceville and Pleasantville (Eastern time). It has been in service since September 17, 2018 and shares its area with 609.

Numbers starting with 640 drew 472 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 132 complaints to the FCC since November 2023. The number on your screen can be faked, so a 640 number proves nothing about where a call came from.

Phone companies holding 640 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
