Who calls from a 901 number

NANPA records the carrier each block of 901 numbers is assigned to. Of the 6.1 million 901 numbers assigned, 41% are with mobile carriers (AT&T Mobility, T-Mobile and Verizon Wireless); 31% with cable, internet-calling, business and other carriers (Onvoy and Bandwidth); 25% with local phone companies (AT&T); 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.
