How to block your number in caller ID on iPhone?
1. Use iPhone Settings to Hide Caller ID
The easiest way is to disable your Caller ID from the iPhone’s settings.
- Open Settings and select Apps at the bottom.
- Scroll down and tap Phone.
- Select Show My Caller ID, and toggle the switch off.
Once you do this, your number will remain hidden for all outgoing calls until you turn it back on.
2. Dialing codes to hide Caller ID in different countries
If you want to hide your number just for a single call, dialing a country-specific code before the phone number works well. Here is a table with codes for many countries:
| Country / Region | Code to block Caller ID (per call) | Notes |
|---|---|---|
| United States, Canada | *67 | Works across NANP (North America) |
| United Kingdom, Ireland | 141 (landline), #31# (mobile) | Hide your number for one call |
| Australia | 1831 (landline), #31# (mobile) | Works on both types |
| France | #31# (mobile), 3651 (landline) | Varies by device type |
| Germany | *31# (most networks), some use #31# | Depends on the provider |
| South Africa | #31# (cell phones), 31 (landline) | Varies by network |
| Japan | 184 | Code for per-call hiding |
| India | #31# (mobile) | Works on GSM; may depend on settings |
| Italy, Spain | *67# (landline), #31# (mobile) | Device-dependent |
| Sweden | #31# | Standard per-call code |
| Switzerland | #31#, or *31# + number | Works as call-by-call |
| Argentina | *31# (landline), #31# (cell) | Varies by line type |
| Brazil, Bulgaria, Croatia, Poland, Romania, & others | #31# | Common across many GSM countries |
The recipient will usually see “No Caller ID” instead of your number. This method works instantly and is great if you don’t want to hide your number permanently. Of course, emergency services will still see your number. This is standard in most places for safety reasons.
3. Ask your carrier to block Caller ID
Mobile carriers can block your caller ID at the network level. This means your number will always be hidden when making calls unless you choose to show it.
- Contact your carrier’s customer service.
- Ask them to enable Caller ID blocking for your line.
- Some carriers may allow you to control this through their official app or website.
Keep in mind that some carriers may charge for this service.
4. Use a second number app
If you want more flexibility, you can use apps that give you a second phone number. Apps like Google Voice or other number-masking services allow you to call without revealing your real number. This is especially useful for work, online selling, or protecting privacy.
5. Contact support if caller ID option is missing
Some users report that the “Show My Caller ID” toggle is missing from iPhone settings. This usually happens if the carrier controls the caller ID.
In such cases, call your carrier and request activation of the feature!
Tips
- Use *67 for quick one-time hidden calls in the US.
- Turn off Caller ID in settings if you want all calls private.
- Save time by creating a contact with *67 pre-dialed for frequent hidden calls in the US.
- Check with your carrier if Caller ID blocking is not available.
- Remember, emergency numbers (like 911) will always see your number even if Caller ID is blocked.
