When someone calls you with a Hidden Caller ID, the incoming call appears as anonymous or private number call on the screen of your iPhone. Hence, we are providing below a workaround or an alternate method to effectively block anonymous private number calls on iPhone.
In general, private number calls can end up being a waste of time, as they are usually made by telemarketers, robots and other unknown callers trying to sell, scam, steal and waste your time.
While you can deal with unknown callers by enabling the Silence Unknown Callers feature as available on iPhone, it can be easily bypassed by private number callers.
1. Block Private Number Calls By Using Do Not Disturb Mode
The most effective way to block Private Number Calls on iPhone is by configuring the Do Not Disturb Mode on your iPhone to allow Calls only from people listed in your Contacts List.
This results in all private number calls on your iPhone being diverted to voicemail, where telemarketers and robots are unlikely to leave a voice message.
1. Go to Settings > Focus > select Do Not Disturb.
2. On Do Not Disturb screen, tap on the People Tab.
3. On the next screen, tap on Allow Calls From and select Contacts Only option in the pop-up that appears
After this, anyone that calls your device with a Private Number will be diverted to voicemail and only those who are listed in your Contacts List will be allowed to ring your iPhone.
However, this happens only when your iPhone is placed in Do Not Disturb Mode and the easiest way to enable DND Mode on iPhone is by going to Control Center and tapping on the Half-Moon icon.
The disadvantage of this method is that it can end up blocking genuine callers who may not be listed in your Contacts List. Hence, it is important that you always check your voicemail, while using this method.
2. Block Individual Private Number Calls on iPhone
If an unknown private number caller is bothering you with unwanted calls, you can block this caller by using “Block this Caller” feature as available in the Phone App.
1. Open the Phone App on your iPhone and tap on Recents tab located in bottom menu.
2. On Recent Calls screen, tap on the “i” icon located next to the Unknown Phone Number.
3. On the next screen, scroll down and tap on Block this Caller.
This will result in this particular private caller being blocked on your iPhone.
