Who calls from a 217 number
NANPA records the carrier each block of 217 numbers is assigned to. Of the 6.9 million 217 numbers assigned, 36% are with local phone companies (AT&T and Frontier); 35% with cable, internet-calling, business and other carriers (Onvoy); 29% with mobile carriers (AT&T Mobility, Verizon Wireless and T-Mobile).
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 | 16% |
| AT&T | Landline | 14% |
| AT&T Mobility | Mobile | 12% |
| Frontier | Landline | 11% |
| Verizon Wireless | Mobile | 9% |
| T-Mobile | 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.
