You can block your phone number from showing on the receiver's caller ID in several ways: 1. Use a prefix code for one-time calls:
- Dial *67 (in the US) before the phone number you want to call. This hides your number for that single call, showing as "Private" or "Blocked" to the recipient
- In some regions or carriers, you can use #31# instead of *67 to block your number for one call
2. Change your phone settings to block your number by default:
- On iPhone:
- Go to Settings > Phone > Show My Caller ID
- Toggle off "Show My Caller ID" to block your number on all calls
- On Android:
- Open the Phone app > Menu > Settings > Call settings > Additional settings > Caller ID
- Select "Hide number" to block your number on all outgoing calls
Note: Some carriers, like Verizon, may not allow blocking your number via phone settings, so you might need to use *67 or contact them
. 3. Contact your mobile carrier:
- You can ask your carrier to block your number by default on your line. They may set it up so your number is always hidden unless you choose to unblock it temporarily with *82
4. Use a burner app or secondary number:
- Apps that provide a second phone number can be used to make calls without revealing your primary number
Important considerations:
- Blocking your number does not work for toll-free or emergency numbers; these can still see your number
- Some recipients or carriers may reject calls from blocked numbers. You can temporarily unblock your number by dialing *82 before the number to allow your caller ID to show for that call
In summary, the easiest way to block your number per call is to dial *67 before the number. For permanent blocking, adjust your phone settings or ask your carrier to enable caller ID blocking on your line.
