Who calls from a 478 number

NANPA records the carrier each block of 478 numbers is assigned to. Of the 4.2 million 478 numbers assigned, 40% are with cable, internet-calling, business and other carriers (Onvoy); 35% with mobile carriers (AT&T Mobility, Verizon Wireless and T-Mobile); 25% with local phone companies (AT&T and Windstream).

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.
