How Do You Make Your Name and Number Appear As Unknown on a Caller ID?
Dial *67 before calling a cellphone or landline to block your name and number. Contact your phone service provider to permanently block outgoing information, which may require a monthly fee.
Newer cellphones offer an internal caller ID block option. Activation prevents information from displaying on all nonemergency outward-bound calls. Apps available for Apple and Android cellphones also provide blocking capabilities. While phone information is blocked when calling consumer phones, your information is always visible to government agencies and emergency services. Alternatively, block unknown inbound callers by contacting your phone service provider and requesting a block. If unavailable, download an app designed to block hidden incoming callers.
