How to Block and Unblock Someone on WhatsApp on iPhone: Updated 2026
iPhone users enjoy sending and receiving messages on WhatsApp, which also lets them share photos and videos. However, there may be times when you do not want to receive messages from someone, even if they are in your WhatsApp contacts. In such cases, you can choose to block someone on whatsapp on iPhone. Unlike deleting a WhatsApp contact, blocking allows you to reconsider later, meaning you can unblock the contact in WhatsApp to resume sending and receiving messages.
For this reason, blocking and unblocking WhatsApp contacts on an iPhone can be a useful feature. If you are unfamiliar with how it works, this article will help you understand it better.

Part 1: What Happens When You Block Someone on WhatsApp?
- The person you blocked will no longer be able to send you messages or make voice or video calls. They also cannot see your last seen status, profile picture, about information, or status updates.
- If you share a group chat with the blocked person, both of you will still be able to read each other's messages in that group.
- Blocking someone on WhatsApp does not remove the existing chat history. You can still view all previous messages exchanged with that contact.
- The person's phone number remains saved on your device or in an account such as iCloud or Gmail. You can manually delete the contact if you no longer want it stored.

Part 3: How to Unblock WhatsApp Contacts on iPhone?
It is not rare that users change their mind shortly after they block the contact. Besides, it is possible that you block a contact by accident. Thus, you also need to know the method to unblock WhatsApp contacts on your iPhone. The means to unblock a contact is similar to add the contact to blocked list. The specific operation is:
- Open up WhatsApp.
- Navigate to "Settings" > "Account" > "Privacy" > "Blocked".

Part 4. How to Know Whether Someone Has Blocked Me or Not?
When you try to block someone, other contacts might tend to block you on WhatsApp as well. Since you won't receive any notification when others block you, how can you know whether they have blocked or not? Here is a way for your reference. When you are blocked by someone on WhatsApp, you will be unable to:
- Deliver messages to the contact. When you fail to send messages, one check mark will appear near the sent messages rather than two check marks.
- Call the contact on WhatsApp.
- See the contact's last seen or online in the chat window.
- View any update on the contact's profile photo.
