Who calls from a 573 number
NANPA records the carrier each block of 573 numbers is assigned to. Of the 6.6 million 573 numbers assigned, 43% are with cable, internet-calling, business and other carriers (Onvoy); 31% with mobile carriers (AT&T Mobility and T-Mobile); 26% with local phone companies (AT&T, Brightspeed and CenturyLink).
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 | 19% |
| Onvoy | Cable, VoIP, other | 15% |
| AT&T | Landline | 10% |
| Brightspeed | Landline | 6% |
| T-Mobile | Mobile | 6% |
| CenturyLink | Landline | 5% |
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.
