You can block your phone number when calling in several ways depending on your device and whether you want to block it temporarily for one call or permanently for all calls.
Temporary Number Blocking (Per Call Basis)
- Dial a special code before the phone number you want to call:
- On most phones in the US, dial *67 before the number. This will make your number appear as "Private" or "Blocked" to the recipient
* Alternatively, some carriers or countries use #31# before the number to block caller ID temporarily
* For home phones, dialing **1831** before the number can block your caller ID for that call
Permanent Number Blocking (All Calls)
- On iPhone:
- Go to Settings > Phone > Show My Caller ID.
- Toggle off to hide your number on all outgoing calls
* Note: Some carriers like Verizon may not support this feature directly
- On Android:
- Open the Phone app.
- Tap the menu (three dots) > Settings > Calls > Additional settings > Caller ID.
- Select Hide number to block your number on all outgoing calls
- You can also contact your mobile carrier to request permanent caller ID blocking for your line
Unblocking Your Number
- To unblock your number for a single call when permanent blocking is on, dial *82 before the phone number
- On some networks, dialing *31# or *31# before the number can unblock it temporarily
Important Notes
- Blocking your caller ID does not work for emergency or toll-free numbers.
- Some recipients or carriers may automatically block calls from private numbers.
- Codes and menu options may vary by carrier and country.
In summary, the easiest way to block your number temporarily is to dial *67 (or #31#) before the number. For permanent blocking, adjust the caller ID settings on your iPhone or Android phone or ask your carrier to block your number by default
