Who calls from a 201 number
NANPA records the carrier each block of 201 numbers is assigned to. Of the 7.7 million 201 numbers assigned, 35% are with cable, internet-calling, business and other carriers (Onvoy and Verizon Business); 32% with mobile carriers (T-Mobile, Verizon Wireless and AT&T Mobility); 31% with local phone companies (Verizon); 2% 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 |
|---|---|---|
| Verizon | Landline | 30% |
| T-Mobile | Mobile | 13% |
| Verizon Wireless | Mobile | 11% |
| AT&T Mobility | Mobile | 8% |
| Onvoy | Cable, VoIP, other | 6% |
| Verizon Business | 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.
