Who calls from a 645 number
NANPA records the carrier each block of 645 numbers is assigned to. Of the 753,000 645 numbers assigned, 59% are with cable, internet-calling, business and other carriers (Onvoy, Eon Telecom and Bandwidth); 41% 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 | 31% |
| Onvoy | Cable, VoIP, other | 30% |
| Eon Telecom | Cable, VoIP, other | 7% |
| Bandwidth | Cable, VoIP, other | 6% |
| Verizon Wireless | Mobile | 5% |
| Wide Voice | 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.
