Who calls from a 414 number
NANPA records the carrier each block of 414 numbers is assigned to. Of the 5.5 million 414 numbers assigned, 37% are with mobile carriers (T-Mobile, AT&T Mobility and UScellular); 31% with local phone companies (AT&T); 26% with cable, internet-calling, business and other carriers (Onvoy); 5% 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 | 13% |
| AT&T Mobility | Mobile | 9% |
| UScellular | Mobile | 8% |
| Onvoy | Cable, VoIP, other | 8% |
| Verizon Wireless | Mobile | 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.
