Who calls from a 563 number
NANPA records the carrier each block of 563 numbers is assigned to. Of the 3.4 million 563 numbers assigned, 38% are with cable, internet-calling, business and other carriers (Onvoy); 32% with mobile carriers (UScellular, T-Mobile and Verizon Wireless); 30% with local phone companies (Qwest (CenturyLink) and Windstream).
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 |
|---|---|---|
| Qwest (CenturyLink) | Landline | 14% |
| Onvoy | Cable, VoIP, other | 13% |
| UScellular | Mobile | 10% |
| T-Mobile | Mobile | 8% |
| Verizon Wireless | Mobile | 7% |
| Windstream | Landline | 7% |
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.
