571 area code
Who calls from a 571 number
NANPA records the carrier each block of 571 numbers is assigned to. Of the 6.3 million 571 numbers assigned, 51% are with cable, internet-calling, business and other carriers (Onvoy, Bandwidth and Verizon Business); 45% with mobile carriers (AT&T Mobility, T-Mobile and Verizon Wireless); 4% with local phone 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 |
|---|---|---|
| AT&T Mobility | Mobile | 18% |
| T-Mobile | Mobile | 17% |
| Onvoy | Cable, VoIP, other | 15% |
| Verizon Wireless | Mobile | 9% |
| Bandwidth | Cable, VoIP, other | 8% |
| Verizon Business | Cable, VoIP, other | 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.
