How to Change Caller ID on Android: Hide or Show Your Number

To change caller ID on Android, you can hide or show your phone number, but changing the name or number that appears requires contacting your mobile carrier. The only documented device-side option is toggling your number's visibility through the Phone app's settings.

How to change caller ID on Android: what you can actually do

The built-in Android caller ID setting does not let you replace your outgoing number or name. It only controls whether your real phone number is shown or hidden when you make a call. Any change to the displayed name or a different outgoing number is managed by your carrier, not the phone itself.

Hide or show your caller ID on Android

Follow these steps to change your caller ID visibility. Note that the exact menu labels vary by device manufacturer and carrier.

Open the Phone app on your Android device.
Tap the three-dot menu or overflow icon, then select Settings.
Tap Calling accounts (or Calls on some devices).
Select the SIM or carrier you use for outgoing calls.
Look for Additional settings or Advanced settings.
Tap Caller ID.
Choose one of the three options: Hide number, Show number, or Network default.
Exit the settings. The change takes effect immediately on your next call.

How caller ID works on iPhone (for comparison)

On iPhone, the only documented built-in change is also to hide or show your own caller ID. Go to Settings > Apps > Phone > Show My Caller ID and toggle it on or off. This setting applies to all outgoing calls from the Phone app.

Changing your caller ID name or number

Android and iPhone do not have a phone setting to change the caller ID name or to replace your outgoing number with a different one. These changes are managed by your mobile carrier. Contact your carrier's customer service or check their website to request a name change or a different outbound number. The exact process and any fees vary by provider. Some carriers may charge a fee for a caller ID number change. As a preliminary step, you can also set up a Caller ID provider like Google Voice or Sideline. For Google Voice specifically: download the app from the Play Store, sign in with your Google account, choose to use your existing number or get a new number, then enable 'Display my Google Voice number as Caller ID' in the app settings.

How to verify your caller ID changes

After adjusting the hide/show setting, make a test call to a friend or another phone you have access to. Ask the recipient what caller ID information they see. If you hid your number, the recipient should see "Private," "Blocked," or "No Caller ID." If you chose to show your number, your usual number should appear. Test across different networks, such as cellular networks and landline phones, to verify caller ID changes display consistently. If the change does not take effect, check that you selected the correct SIM in the settings, reboot your device, or contact your carrier if you were trying to change the name or number.

Frequently Asked Questions

Can I change the caller ID on my Android phone?

Yes, it is possible to change your caller ID visibility via the Phone app settings to hide or show your number.

Why can't I change my caller ID on Android?

Your carrier may not support the feature, your software version may lack the option, or your carrier plan may have restrictions.

Can I hide my caller ID for a single call on Android?

Yes. This temporarily hides your number for that one call only, regardless of your default caller ID setting.

Why is the caller ID option missing on my Android phone?

The option may be absent if your carrier does not support caller ID control on your device or plan. Some carriers block this setting entirely. If you cannot find it in the Phone app settings, contact your carrier to confirm whether the feature is available for your line.

Does hiding my caller ID affect incoming calls?

No. Changing your outgoing caller ID setting only affects how your number appears to people you call. Incoming calls still show the caller's information normally, and your phone continues to receive calls as usual.

Can I use an app to change my caller ID name or number?

No official app is documented to change the outbound caller ID name or number on Android. Third-party apps that claim to do this typically route calls through their own systems, which can affect call quality and privacy. The safest method is to contact your carrier.

How do I hide my phone number on WhatsApp?

WhatsApp does not use your phone's caller ID for calls made through the app. To hide your phone number on WhatsApp, adjust your privacy settings: go to Settings > Privacy > Phone Number and select who can see your number.
