Who calls from a 504 number
NANPA records the carrier each block of 504 numbers is assigned to. Of the 5.6 million 504 numbers assigned, 39% are with mobile carriers (T-Mobile, AT&T Mobility and Verizon Wireless); 31% with local phone companies (AT&T); 26% with cable, internet-calling, business and other carriers (Onvoy and Bandwidth); 4% with paging 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 | Landline | 31% |
| T-Mobile | Mobile | 20% |
| AT&T Mobility | Mobile | 11% |
| Onvoy | Cable, VoIP, other | 8% |
| Verizon Wireless | Mobile | 7% |
| Bandwidth | Cable, VoIP, other | 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.
