That said, how to stop getting messages from unknown numbers on WhatsApp? Well, there are a few methods you can use for that, and they’re as follows.

1. Block the Unknown Number

The first and the simplest solution is to block the number.

When you block someone on WhatsApp, they won’t be able to send you messages or call you. Plus, they won’t be able to see your profile picture or about info either. That said, here’s how to block unknown number on WhatsApp.

• Open the WhatsApp app on your Android device or iPhone.
• Open the chat you’re receiving the messages from. Tap on the number on the top.

• Select “Block [Number]”, then hit “Block” again to confirm.

  

The contact has now been blocked from sending you any more messages.

2. Report the Unknown Number

If the messages you’re receiving are spam, i.e., they look like marketing material or copy-pasted messages, you can report it to WhatsApp. When you do this, WhatsApp team will take a look at the contact and ban them from WhatsApp if they’re a spammer.

To report someone, simply follow the steps below.

• Open WhatsApp on your phone.
• Open the chat you want to report.
• Tap the number on the top.

• Select “Report [Number]”, then hit “Report” to confirm.

  
• You can also select “Report & Block” to report the number to WhatsApp, as well as block the number from sending you messages at the same time.

Part 4: How to Send WhatsApp Messages to Unsaved Number

If you want to send someone a WhatsApp message but don’t want to save their number, you might be wondering how to do that. That’s because WhatsApp doesn’t offer any way to do that.

However, there’s a workaround you can use for it, and it’s as follows.

• Open your browser of choice, i.e., Chrome, Safari, Firefox, etc.
• In the URL bar, type https://wa.me/phonenumber — but replace the term “phonenumber” with the actual number of the person you want to send the message to. Use the full number with country and area code, but don’t put the “+” sign.

• Hit enter — and a popup will appear asking you to open WhatsApp. Hit “Open”.

  
• Now, you will be able to write and send a message.

Tips about Spam and Unwanted Messages

If you’d like to know what WhatsApp spam looks like, this section has got you covered.

• If the number is claiming to be someone from WhatsApp and says you need to pay them to keep using WhatsApp — that’s spam!
• If they claim to be from authorities but have grammatical or factual mistakes, that’s spam too.
• Last but not least, if they ask you to forward them a message or share your personal information, that’s spam, too.

Beware of such contacts and don’t ever give them what they ask for!
