To hide your phone number when making a call, you have several options depending on your device and carrier:
For Android Phones
1. Use a Prefix Code for One-Time Calls
- Dial *67 before the phone number you want to call. This will block your number for that single call, showing it as "Private" or "Blocked" on the recipient's phone. You must enter *67 before every call you want to keep private
- In some regions, such as India, the prefix code might be #31# instead of *67 (e.g., #31#1234567890)
2. Change Caller ID Settings to Hide Number Permanently
- Open the Phone app.
- Tap the menu (three dots) and go to Settings > Calls or Supplementary services.
- Find Caller ID or Show my caller ID.
- Select Hide number or Never to block your number for all outgoing calls.
- To show your number for a specific call after this, dial *82 before the number
3. Contact Your Mobile Carrier
- Ask your carrier to enable permanent caller ID blocking on your account. Some carriers also provide apps to manage this feature
4. Use Third-Party Apps
- Apps like Burner, Hushed, or Dingtone can provide temporary numbers and control over caller ID for additional privacy
Limitations:
- You cannot hide your number when calling emergency services (e.g., 911) or toll-free numbers
- Some recipients may have settings to block calls from private or unknown numbers
For iPhones
- You can hide your number by going to Settings > Phone > Show My Caller ID and turning it off (if supported by your carrier).
- Alternatively, dial *67 before the number to block your number on a per-call basis
