When you block your caller ID and 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.

As long as your caller ID is hidden, your call recipient sees “Private,” “Anonymous,” or a similar term in place of your phone number. Later, you can toggle off the option to start showing your number.

Note: Not all carriers allow you to hide your phone number. If you don’t find the option to block the caller ID, your carrier has probably locked 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 carrier ensures your phone number is hidden on the recipient’s phone.

However, 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. Make sure to include the area code in the phone number.

For example, to dial (555) 555-1234 , you’d type:

*675555551234

If you’re with AT&T, prefix your phone number with *67 and add the # key at the end.

To call (555) 555-1234 , enter the following:

*675555551234#

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


Don’t want calls from unknown people on Android? If so, there’s a way to disable those calls.
