Who calls from a 608 number
NANPA records the carrier each block of 608 numbers is assigned to. Of the 6.9 million 608 numbers assigned, 37% are with cable, internet-calling, business and other carriers (Onvoy); 31% with local phone companies (AT&T and Brightspeed); 30% with mobile carriers (UScellular, Verizon Wireless and AT&T Mobility); 1% with paging companies.
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% |
| AT&T | Landline | 10% |
| UScellular | Mobile | 10% |
| Brightspeed | Landline | 8% |
| Verizon Wireless | Mobile | 8% |
| AT&T Mobility | 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.
