Who calls from a 669 number
NANPA records the carrier each block of 669 numbers is assigned to. Of the 2.3 million 669 numbers assigned, 57% are with cable, internet-calling, business and other carriers (Onvoy, Bandwidth and Teleport Communications (AT&T)); 42% with mobile carriers (T-Mobile, 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 |
|---|---|---|
| Onvoy | Cable, VoIP, other | 25% |
| T-Mobile | Mobile | 19% |
| AT&T Mobility | Mobile | 12% |
| Verizon Wireless | Mobile | 10% |
| Bandwidth | Cable, VoIP, other | 10% |
| Teleport Communications (AT&T) | Cable, VoIP, other | 4% |
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.
