Nothing is more irritating for an iPhone user than a call with no caller ID. In case you don’t know exactly what a no-caller ID means and why people make them, here’s an explanation. The purpose of a no-caller ID call is to safeguard the caller’s privacy or to prevent call recipients from learning the caller’s whereabouts.
Are you looking for the best way to stop these calls without caller ID? Follow these instructions to block calls on your iPhone that don’t have caller ID.
Input a contact with the name “No Caller ID”.
To begin blocking calls with no caller ID, add a contact to your phone with the name “No Caller ID.” Here’s how to do it; On your iPhone, open the Contacts app, hit the “+” symbol, and then input “No Caller ID” for the first and last names. The other fields are optional.
Block the “No Caller ID.”
Blocking your newly formed “No Caller ID” contact is what you should do next. Open the Settings app on your iPhone, pick “Phone,” then “Blocked Contacts,” and finally “Add New.” The “No Caller ID” contact you just made can be located. You can then choose it, and then you press “Block Contact.” It’s as simple as that.

Turn on Not Disturb mode
With the iPhone’s Do Not Disturb feature, incoming calls and notifications can be suppressed. It may be turned on by tapping the crescent moon icon in the Control Centre on your iPhone. To modify the feature, open the Settings app and choose “Do Not Disturb.” This will mute all incoming calls from obscene numbers.
Download a Third-party Application
The App Store is filled with numerous third-party applications that can block calls without caller ID. Truecaller is the best at this. It can recognize and stop spam calls, including those without caller ID. Also, it is free to download at no cost.
