Who calls from a 817 number

NANPA records the carrier each block of 817 numbers is assigned to. Of the 7.7 million 817 numbers assigned, 37% are with local phone companies (AT&T); 30% with mobile carriers (AT&T Mobility, T-Mobile and Verizon Wireless); 30% with cable, internet-calling, business and other carriers (Onvoy and Level 3); 3% with paging companies.

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.
