WhatsApp: How to block contacts on WhatsApp – Can they see you have blocked them?

allows users to send messages to their contacts over an internet connection instead of using up your text allowance.

The app has the ability to store dozens of your contacts for quick and easy communication – along with a function to set up group chats.

But sometimes you may want to stop talking to someone – or stop them from talking to you.

Luckily, you can block contacts on WhatsApp – which stops any of their messages being delivered to your phone.

How do you block someone on WhatsApp?

Blocking someone on WhatsApp is different depending on which phone you use.

Android

If you have an Android phone, open the app and tap on the menu button. 

Go to settings, Accounts, Privacy and then select Blocked Contacts. 

This will show you a list of any contacts you may have already blocked from your WhatsApp.

To add another contact, tap the add contact icon and select the contact out of the list. 

iPhone 

For iPhone users, go to the Settings icon at the bottom right-hand part of your phone and again click through, Settings, Contacts, and Privacy. 

Tap on Blocked and then hit Add New to select the person you want to stop communicating with. 

If it is an unknown number that you don’t recognise, simply open up a message window with the contact and select Block. 

If the message is spam, you can report it as such by selecting Report Spam.

How to unblock a contact

If at any point you change your mind about blocking someone, you can later unblock a contact.

To do this, simply go back through settings to your blocked contacts and swipe left or hold your finger on the contact (iPhone and Android respectively), and then select Unblock. 

What happens when you block someone from WhatsApp? 

Blocking a contact from your WhatsApp stops you from seeing each other altogether. 

A blocked contact will no longer be able to message you, receive messages or see when you are online. 

Can you see if you’ve been blocked?

Although you will not be notified if someone blocks you, there are a couple of indicators to look out for.

• You can’t see a contact’s last seen or online in the chat window

• You can’t see updates to a contact’s profile photo

• Messages sent to a contact who has blocked you will just show one checkmark and never show a second check mark

• Calls to a user who has blocked you will not go through
