When you block your caller ID and you call someone, your phone number is not displayed on the recipient’s phone. You can hide your caller ID on your iPhone, Android phone, as well as your carriers like AT&T, T-Mobile, and Verizon. We’ll show you how.

Whenever your caller ID is hidden, the recipient of your call will see “Private,” “Anonymous,” or a similar term instead of your phone number. Later, you can disable the option to start displaying your number.

Note: Not all carriers allow you to hide your phone number. If you don’t see the option to block Caller ID, it’s likely that your carrier has blocked it. In this case, contact your service provider for more information.

Disable Caller ID for a single call with AT&T, T-Mobile, and Verizon

To disable your caller ID for individual calls and not for all calls, use your carrier’s prefix before dialing a phone number. This way, your provider makes sure that your phone number is hidden from the recipient’s phone.

However, please note that your phone number will be displayed when you call toll-free numbers or emergency services.

To hide your caller ID on Verizon or T-Mobile, add *67 before the phone number you want to dial, and then press the call key. Be sure to include the area code in the phone number.

For example, to mark (555) 555-1234 you would write:


If you work with AT&T, precede your phone number with *67 and add the # key at the end.

And that’s how you enjoy privacy while still being able to talk to people. Very useful!
