Who calls from a 606 number
NANPA records the carrier each block of 606 numbers is assigned to. Of the 5.6 million 606 numbers assigned, 38% are with mobile carriers (AT&T Mobility, Appalachian Wireless and Verizon Wireless); 33% with local phone companies (Windstream and AT&T); 30% with cable, internet-calling, business and other carriers (Onvoy).
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 | 18% |
| Windstream | Landline | 17% |
| Onvoy | Cable, VoIP, other | 16% |
| AT&T | Landline | 10% |
| Appalachian Wireless | Mobile | 7% |
| Verizon Wireless | Mobile | 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.
