Who calls from a 731 number
NANPA records the carrier each block of 731 numbers is assigned to. Of the 3.5 million 731 numbers assigned, 42% are with cable, internet-calling, business and other carriers (Onvoy, Aeneas Communications and Bandwidth); 30% with local phone companies (AT&T); 27% with mobile carriers (AT&T Mobility and Verizon Wireless).
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 | Landline | 22% |
| Onvoy | Cable, VoIP, other | 14% |
| AT&T Mobility | Mobile | 13% |
| Verizon Wireless | Mobile | 10% |
| Aeneas Communications | Cable, VoIP, other | 5% |
| Bandwidth | Cable, VoIP, other | 4% |
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.
