Who calls from a 447 number
NANPA records the carrier each block of 447 numbers is assigned to. Of the 1.3 million 447 numbers assigned, 55% are with cable, internet-calling, business and other carriers (Onvoy, Teleport Communications (AT&T) and Telnyx); 45% with mobile carriers (AT&T Mobility and Verizon Wireless).
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 Mobility | Mobile | 38% |
| Onvoy | Cable, VoIP, other | 26% |
| Teleport Communications (AT&T) | Cable, VoIP, other | 5% |
| Verizon Wireless | Mobile | 4% |
| Telnyx | Cable, VoIP, other | 3% |
| Commio | Cable, VoIP, other | 3% |
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.
