How to Block No Caller ID on iPhone?[4 Ways]

“I got a no caller id call, should I answer it?”Usually, calls with no caller ID originate from spammers or other persons who are attempting to obtain personal information from you.

When someone calls you from a number that appears on your screen as "no caller ID," it signifies that the person who is phoning you has employed a method to prevent their phone number from being accessible to you, and this is what no caller ID means. These folks are deliberately concealing their contact information so that you can't track down their calls.

A person attempting to phone you without seeing their number, a telemarketer attempting to sell you something, or a charity or organization seeking money might all be calling you with no caller ID. Even if you have no idea who is phoning you, you should be mindful that they do not wish to share their contact information with you. As a result, learning how to block no caller IDs is critical in order to eliminate spam and hackers and address other concerns.

Way 3: Create A New Contact

How to block no caller id on iPhone 2023? The third option is to create a new contact with the name "Do Not Answer" or "No Caller ID" to block unknown calls.

However, you may go around this by establishing a contact that looks like an unknown number. Here's how you can do it:

1. To add a new contact, go to Contacts and hit the Plus symbol.

2. In the space for the contact's name, type "No Caller ID."

3. Then type "000-000-0000" as the new contact's phone number.

4. To save, click Done.

5. Next, go through the profile of this newly added contact until you find the Block this Caller option and press it.

6. To confirm your decision, select Block Contact.

Any hidden or private numbers will now be recognized by your iPhone as a blocked number, preventing your phone from ringing if you get a call from an unknown number.
