Caller ID is a technique that enables a phone to show the number of other phones that are connected to it. This may be done on any phone. That will be shown as the caller ID for outgoing calls that you make. When you are on the receiving end of a call, the inbound caller ID is what appears on your screen.
On every smartphone, even Androids, you have the simple ability to modify the caller ID shown on incoming calls. This feature is available on almost all modern phones. Other than deciding whether to show or conceal your number, you do not have any control over the outgoing caller ID that is sent with your calls.
How To Change Caller Id On Android? Using Android Settings
Open your Android’s Phone app. To access the Phone application, choose the symbol that looks like a white landline receiver set against a green or blue backdrop.
There are several carriers who do not allow the ability to hide your caller ID under the settings. If this procedure is unsuccessful, you should attempt one of the other methods described in this page.
Tap the MORE or button. You’ll find it in the upper-right hand corner of the display. A menu that can be dropped down will appear.
Tap Settings. This choice may be found in the menu that drops down. This action brings up the caller settings menu. 
Tap the More settings button after scrolling down. You should be able to locate this at the bottom of the page.
Tap Please display your caller ID. It is located rather close to the top of the page. When you do so, a menu will either pop up or slide down into the screen.
Tap Hide number. You can find this option in the menu. When you do so, your caller ID will be hidden as long as it is allowed by your carrier and/or your area.
If you do not see this option, then the caller ID masking feature is not supported by your carrier. You may contact your carrier to attempt to request this functionality, as the vast majority of Android phones already allow caller ID-masking on their own, but it is likely going to cost you a charge in order to do so.
