To keep your Android phone number private, you can use several methods to hide your caller ID when making calls. Here’s how:

1. Use the 67 Prefix for Individual Calls

For a one-time call, you can prepend *67 to the recipient’s number to block your caller ID for that specific call.

• Open your Phone app.

• Dial *67 followed by the recipient’s phone number.

• Press the call button.

The recipient will see “Private” or “Blocked” instead of your number. 

2. Hide Your Number for All Outgoing Calls

To hide your number for all outgoing calls, follow these steps:

• Open the Phone app.

• Tap the three-dot menu icon (usually at the top-right corner).

• Select “Settings.”

• Tap “Calls” or “Supplementary services.”

• Choose “Caller ID.”

• Select “Hide number.”

This setting may vary depending on your device and carrier. 

3. Contact Your Carrier

Some carriers offer services to block your caller ID for all outgoing calls. Contact your mobile provider to inquire about this option. 

4. Use a Burner Number

For temporary privacy, consider using a burner number through apps that provide disposable phone numbers. This allows you to make calls without revealing your personal number. 

Important Considerations

• Emergency services and toll-free numbers will always see your real number, regardless of these settings.

• Some third-party apps may still access your real number.
