How to Hide Your Number During Calls on Android

Hiding your caller ID on Android can be useful for maintaining privacy, avoiding unwanted calls, or simply preventing your number from being displayed when making calls. Whether you’re concerned about privacy or just want to test how your number appears to others, knowing how to hide your number can give you greater control over your outgoing calls. Before you begin, ensure your carrier supports caller ID blocking, as some providers may restrict this feature or charge extra fees. The following guide walks you through simple, effective methods to hide your number during calls on Android devices.

What You’ll Need

• An Android smartphone with a working cellular connection
• Access to your phone’s dialer or call settings
• Optional: Carrier support for caller ID blocking (most carriers support this)

Step-by-Step

1. Check if your carrier supports caller ID blocking: Before changing settings on your device, verify with your mobile provider if they allow hiding caller ID. This can usually be confirmed via their website or customer support.
2. Use the USSD code to hide your number temporarily:
   • Open your phone’s dialer app.
   • Dial *31# and press the call button.
   • You’ll hear a confirmation tone or message indicating your caller ID is now hidden for the next call.
   • Note: This method typically applies to individual calls and resets after each call unless you disable it permanently.
3. Set caller ID to private via phone settings (permanent method):
   • Open the Phone app on your Android device.
   • Tap on the three-dot menu icon (usually top right) and select Settings or Call Settings.
   • Look for an option called Additional Settings or Caller ID.
   • Tap on Caller ID and select Hide Number or Network Default > Hide Number.
   • If your device doesn’t have this option, proceed to the next method.
4. Change caller ID settings via your carrier’s support page or customer service: Some carriers allow you to set this feature permanently through their app or website. Login to your account and look for caller ID settings, then select the option to hide your number.
5. Use a third-party app or dialer (if supported): Some third-party dialer apps include options to hide caller ID. Download a reputable app from the Google Play Store, and configure the caller ID settings accordingly.

Common Mistakes

• Assuming all methods work without verifying carrier support — always check if your provider supports caller ID blocking.
• Forgetting to reset your caller ID settings after testing — your number may remain hidden longer than intended.
• Using third-party apps that aren’t trustworthy — always download from reputable sources to protect your privacy and security.
• Not understanding that some methods only hide your number temporarily, not permanently.
• Neglecting to check if the recipient’s device or network displays caller ID differently.

Tips

• To hide your number for all outgoing calls permanently, use the *#31# USSD code or update your carrier settings.
• Remember that some recipients or services (like emergency services) may still see your number regardless of your settings.
• If you want to hide your number only for specific calls, dial *31# before each call.
• Test your settings by calling a friend or using a service that displays caller ID to confirm your number is hidden.
• Keep your device’s software updated to ensure all features and settings work correctly.

Troubleshooting

If your caller ID isn’t hiding as expected:

• Verify with your carrier: Some carriers override device settings. Contact customer support to confirm your account has caller ID blocking enabled.
• Check your phone’s settings: Ensure you’ve correctly set the caller ID to hide in your call settings or dialer options.
• Use the USSD code: Dial *#31# before making calls to temporarily hide your number. If it works, the issue may be with your device settings.
• Disable third-party apps: If you’re using apps that modify call behavior, disable or uninstall them to see if that resolves the issue.
• Restart your device: Sometimes, a simple restart can resolve configuration glitches.
• Update your device software: Outdated software can cause settings to malfunction; keep your Android up to date.

If none of these steps work, contact your carrier for further assistance, as some providers may have restrictions or specific procedures for caller ID blocking.
