Who calls from a 353 number

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 |
|---|---|---|
| Onvoy | Cable, VoIP, other | 59% |
| Verizon Wireless | Mobile | 20% |
| Bandwidth | Cable, VoIP, other | 7% |
| HD Carrier | Cable, VoIP, other | 5% |
| Ahoi | Cable, VoIP, other | 2% |
| T-Mobile | Mobile | 2% |
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.
