Who calls from a 646 number

NANPA records the carrier each block of 646 numbers is assigned to. Of the 7.8 million 646 numbers assigned, 46% are with cable, internet-calling, business and other carriers (PAETEC (Windstream) and Level 3); 46% with mobile carriers (T-Mobile, Verizon Wireless and AT&T Mobility); 9% with local phone companies (Verizon).

That is who the numbers were assigned to: people keep their number when they change carrier, so any one number may have moved since.

An area code says where a number was issued, not where the caller is: people keep their numbers when they move, and caller ID can be set to show any number, which the FCC calls spoofing. If a call you did not expect asks for money or personal details, the FCC advises hanging up and calling the company back on a number you look up yourself. Unwanted calls can be reported to the FTC at ReportFraud.ftc.gov.
