How to hide your number on Android On Android, the name of specific settings may vary depending on which version of Android you're on and what brand of smartphone you're using.

Since the 1990s, anyone you call sees your number before they answer, but it is possible to opt out of this if you'd rather retain your privacy.

Many smartphones have the option to hide your number when making a phone call built in, making it easier to keep your number private.

You can make a call private by hiding your phone number in a few different ways, including using your phone's settings.

If you don't want people to know you're calling, you can hide caller ID by blocking your own number on both landlines and smartphones.

Afterward, tap the Hide Number button. Lifewire says you may hide your phone number when calling by adding “*67” before entering the number you’d like to contact.
