How to Block Unknown Numbers on WhatsApp

WhatsApp is one of the most used messaging apps in the world. Given the mass adoption, you also encounter a ton of spam on WhatsApp. Whether it’s the flood of good morning messages from family members or random messages from unknown numbers. Thankfully, WhatsApp lets you block unknown numbers.

While it’s pretty straightforward to block unknown numbers that message you upfront, you might even want to block numbers that haven’t texted you. If you’re tired of receiving WhatsApp messages from unknown numbers, follow along.

Block WhatsApp Numbers Saved in Contacts

Before we tell you how to block WhatsApp messages from unknown numbers, you might also want to know how to block WhatsApp contacts. It’s simple, but for those unaware, here’s how it’s done.

Step 1: Open the chat window of the contact that you want to block. Tap on the name on the top.

Step 2: Scroll down to the bottom of the screen. You should see the Block button. Tap on it. You can unblock the contact again using the same button that would now say Unblock.

Block Unknown WhatsApp Numbers Not in Contacts

These are the people who send you spammy links with deals and discounts that will ‘blow’ your mind. When you receive such a message from an unknown number, open the chat window and ask if he/she knows you.

Why? Last week I joined Bob Proctor’s webinar and his assistant reached out via WhatsApp. Fortunately, I didn’t block her right away. Don’t go on a blocking spree just because you are feeling annoyed. Maybe, it concerns you in some way.

If you feel the message is spam, this is what you have to do.

Step 1: Open the chat window in WhatsApp. At the bottom, you will see two options: Block or Add to contacts.

Step 2: Tap on Block. You will then see a prompt asking you to either Block the number or Block and Report it.

Step 3: Tick the checkbox if it’s a spammy message or an attempted scam. If it’s just a friend you want to avoid, you can simply Block them. This way, you can also block unknown number calls on WhatsApp.

Note: When you report a WhatsApp number, the number is added to a Watchlist maintained by WhatsApp. If the number is reported multiple times by a lot of users, it will be banned temporarily. Think of it as a warning to curb spam. WhatsApp may ban the number permanently at its sole discretion. Exact details are not available on their official help page.
