Who calls from a 904 number
NANPA records the carrier each block of 904 numbers is assigned to. Of the 7.8 million 904 numbers assigned, 37% are with mobile carriers (T-Mobile, AT&T Mobility and Verizon Wireless); 36% with cable, internet-calling, business and other carriers (Onvoy and Bandwidth); 26% with local phone companies (AT&T); 2% 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.
| Carrier | Kind | Share |
|---|---|---|
| AT&T | Landline | 24% |
| T-Mobile | Mobile | 18% |
| Onvoy | Cable, VoIP, other | 11% |
| AT&T Mobility | Mobile | 11% |
| Verizon Wireless | Mobile | 8% |
| Bandwidth | Cable, VoIP, other | 5% |
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.
