Who calls from a 728 number
NANPA records the carrier each block of 728 numbers is assigned to. Of the 666,000 728 numbers assigned, 56% are with mobile carriers (Verizon Wireless, AT&T Mobility and T-Mobile); 44% with cable, internet-calling, business and other carriers (Onvoy, HD Carrier and Bandwidth).
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 |
|---|---|---|
| Verizon Wireless | Mobile | 27% |
| Onvoy | Cable, VoIP, other | 23% |
| AT&T Mobility | Mobile | 21% |
| T-Mobile | Mobile | 5% |
| HD Carrier | 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.
