How to Block Someone on WhatsApp for iPhone and Android

WhatsApp connects you via chat and calls to your friends, family, and businesses. But at times, it can get annoying too. For instance, when distant acquaintances or brands start spamming you with their promotions or send useless messages, you may mute or block them. Want to know the steps? Let me tell you how to block someone on WhatsApp for iPhone and Android.

What Hap­pens When You Block Some­one on WhatsApp?

After you block a contact:

    • WhatsApp does not notify the other party that you have blocked them.
    • The messages they send will not be delivered to you, ever! The sender will see only a single tick.
    • Note: Group chat is not affected. If you and the person you blocked are part of the same WhatsApp group, you will continue to see each other’s messages in that group.
    • They can not audio or video call you personally or even via group call.
    • Your profile picture, status, about, online status, last seen, etc. won’t be visible to the blocked contact.
    • The phone number stays saved to your mobile phone or the account like iCloud, Gmail. You may manually delete it if needed.

How to Block an Unknown Number on WhatsApp

In this context, by ‘unknown number’ we mean, contact number that is not saved to your phone. When such a person messages you, this chat app lets you know that the sender is not a part of your contact.

Below the message, you see three options – Block, Report, Add to Contacts. Tap on BlockBlock to easily and immediately prevent all future conversations with that person.

Pro Tip: WhatsApp also has a Report option. It is for spam messages. If you tap on it and then choose Report and Block, the entire message history gets deleted.

So, if you wanted to take screenshots or screen recording of the chat as evidence or something, make sure you do that first before choosing to Report and Block.

How to Block Someone in Whatsapp Group Chat on iPhone and Android

If you and a person you blocked are part of the same WhatsApp group, you both continue to see each other’s messages in the group. It does not matter whether their number is saved to your phone or not. Outside the common group, all effects of blocking continue. That is, the blocked person can not see your profile picture, status, about, last seen, online status, call you, send personal messages, etc.

So, as of now, the only way to prevent someone from seeing your group message is to ask the group admin to remove that participant from the group. Or, worse, you can exit the group! Finally, it may sound inefficient, but you can create a new WhatsApp group and add everybody except that one person.

Interesting Observation: The blocked person sees the messages in a group. But if you make a group WhatsApp call, the blocked contact will not get any notification for the call and won’t be a part of the group call.

Finally, if you want to block the group admin, here is how to do that. This will not exit you from the group or prevent you from sending messages in that group. This only blocks the group admin on a personal level. Everything else in the group will continue to work.

  1. Open the group chat in WhatsApp and tap on the group name from the top.
  2. Tap on the admin’s name or number.tap on whatsapp group tap on group name and tap on admin name
  3. Tap Info.
  4. Scroll down and tap on Block ContactBlock.tap on info and select block to block someone in whatsapp group chat on iphone

Note: You may also prevent yourself from being added to groups. To do this, tap on Settings inside WhatsApp → Accounts → Privacy → GroupsNobody. Now, the admin will have the option to invite you to a group privately. You can accept or decline.
