Maintaining your privacy while making calls has become more important than ever. Whether you’re making a professional call or simply wish to protect your identity, knowing how to hide your number when calling on Android can be very useful.
In this guide, you’ll learn how to make your phone number private on Android, how to unhide caller ID on Android, and what codes or apps can help you achieve complete anonymity.
Hide/Unhide Caller ID on Android
Sometimes, you may have hidden your caller ID in the past and want to show it again for certain calls. Whether you’re aiming to hide your caller ID or unhide it, Android provides a simple way to do both. Hide/unhide caller ID on Android can be done through your phone’s built-in settings or through apps like Google Voice. In this section, we will explore both options in detail.
How to Hide Your Caller ID on Android
To hide your caller ID on Android, follow these steps:
- Open the Phone app on your device.
- Tap the three-dot menu (located in the top-right corner).
- Go to Settings.
- Select Calls or Calling Accounts.
- Tap on Caller ID.
- Choose Hide number.
Once this option is selected, your number will be shown as Private or Unknown to the people you call. This method ensures that your caller ID is hidden for all outgoing calls.
Important: Some carriers might override this setting and require you to use an alternative method. Contact your carrier if the setting doesn’t work.
How to Unhide Your Caller ID on Android
If you previously hid your caller ID and now want to reveal it to the people you call, the steps are just as simple:
- Open your Phone app.
- Tap the three-dot menu and go to Settings.
- Navigate to Calls or Calling Accounts.
- Tap on Caller ID.
- Select Show number.
By selecting Show number, your phone number will be visible to all recipients for your outgoing calls.
Important Note: If you have used apps like Google Voice to hide your caller ID earlier, make sure you check and update the caller ID settings within the app as well.
It Is Possible to Make Your Number Private Calling Someone on Android
Many Android users ask: Is it possible to make your number private when calling someone on Android? The answer is yes! Android gives you several methods to hide your number temporarily or permanently.
1. Hide Caller ID Through Phone Settings
Almost all Android phones come with a built-in option to hide your caller ID:
- Open the Phone app.
- Go to Settings > Supplementary Services (or Additional Settings).
- Tap Caller ID, then select Hide number.
When enabled, your number will appear as Private or Unknown to the receiver for all outgoing calls.
2. Use a Prefix Code Before Dialing
If you don’t want to permanently hide your number but only for occasional calls, use a prefix code. In most countries, dialing #31# before the number hides your caller ID.
For example:
Dial #31#1234567890 to make a private call.
Tip: Prefix codes may vary by country, so confirm which code works in your region.
3. Use Google Voice App to Make Private Calls
Google Voice offers an easy way to control your caller ID visibility:
- Open the Google Voice app.
- Tap the Menu icon and go to Settings.
- Under Calls, turn on Anonymous caller ID.
Once activated, all calls made through Google Voice will not display your actual number.
How to Make Your Phone Number Private on Android
If you’re looking for permanent ways to make your phone number private on Android, you have excellent options available.
Change Caller ID Settings in Google Voice
To make your phone number private for all calls using Google Voice:
- Open the Google Voice app.
- Tap Menu > Settings.
- Under Calls, toggle ON Anonymous caller ID.
Remember: Hiding your caller ID on one device with your Google Voice account means it’s hidden across all devices logged into the same account.
Hide Caller ID for Individual Calls
For single calls where you want anonymity:
- Open the Google Voice app.
- Tap Calls at the bottom.
- Enter the appropriate prefix code (e.g., *67 in the U.S. or #31# in India) before the number.
- Tap Call.
This hides your caller ID for that one call without affecting future calls.
Does Any Code to Unhide Caller ID?
When you’ve hidden your caller ID and want to reveal it for a specific call, use a dialing code.
Code to Unhide Caller ID for a Single Call
If your number is normally hidden, but you want it to show for one call:
- Dial *82 (in the U.S. and some other countries) before the number.
Example:
Dial *821234567890 to reveal your number to the recipient.
Note: Prefix codes like *82 may not work on all carriers or in every country, but they’re common on GSM networks like Airtel, Vodafone, and Jio in India.
Additional Ways to Hide Your Phone Number on Android
Beyond settings and codes, here are advanced methods to keep your number private:
Use Third-Party Dialer Apps
Apps like Truecaller, Hushed, and Burner offer anonymous calling features, allowing you to make private calls without changing your actual phone settings.
Contact Your Carrier
Most carriers provide a caller ID blocking service. You can:
- Call customer service and request permanent blocking of your caller ID at the network level.
- Some providers may charge a small fee for this service.
Popular carriers in India supporting caller ID blocking include:
Jio, Airtel, Vi (Vodafone Idea), BSNL.
Always ask if they offer temporary caller ID block codes too.
Limitations When Hiding Caller ID
Even if you follow all steps to hide your number on Android, there are situations where caller ID hiding might not work:
- Calls to emergency numbers (e.g., 112 in India) will always transmit your caller ID.
- Some recipients have services that automatically reject anonymous calls.
- Certain businesses and government offices block calls from hidden numbers.
Understanding these limitations ensures you’re not caught off guard when your privacy settings don’t work.
