Who calls from a 660 number
NANPA records the carrier each block of 660 numbers is assigned to. Of the 3.7 million 660 numbers assigned, 40% are with cable, internet-calling, business and other carriers (Onvoy); 39% with local phone companies (Grand River Mutual Tel Co, CenturyLink and AT&T); 21% with mobile carriers (Verizon Wireless and AT&T Mobility).
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 | 12% |
| Grand River Mutual Tel Co | Landline | 10% |
| CenturyLink | Landline | 7% |
| Verizon Wireless | Mobile | 6% |
| AT&T Mobility | Mobile | 6% |
| AT&T | Landline | 6% |
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.
