How to Block Spam Calls and Messages on WhatsApp

WhatsApp has become a prime target for spammers and scammers due to its massive user base. Unwanted calls and messages can quickly become a nuisance, disrupting your daily communication. Fortunately, WhatsApp offers several built-in features to combat this issue. Let’s explore effective ways to keep your WhatsApp experience spam-free and secure.

Silence Unknown Callers

One of the most effective ways to reduce spam on WhatsApp is to silence calls from unknown numbers. This feature prevents your phone from ringing when you receive a call from a number not in your contacts list.

Step 1: Open WhatsApp and tap on the Settings icon.
Step 2: Navigate to Privacy > Calls.
Step 3: Toggle on the “Silence Unknown Callers” option.

With this setting enabled, calls from unknown numbers will be silenced, but they’ll still appear in your call log. This allows you to check for any important missed calls while avoiding disruptions from potential spammers.


Block Messages from Unknown Senders

If you’re receiving a high volume of spam messages, WhatsApp offers an advanced setting to block messages from unknown senders automatically.

Step 1: Go to WhatsApp Settings.
Step 2: Tap on Privacy > Advanced.
Step 3: Enable the “Block Unknown Account Messages” option.

This setting helps filter out potential spam messages, especially those sent in bulk by automated systems. However, be aware that it may also block legitimate messages from new contacts, so check your message requests periodically.


Control Group Invitations

Spammers often add users to groups without their consent to distribute unwanted content. You can prevent this by adjusting your group privacy settings.

Step 1: Open WhatsApp Settings.
Step 2: Go to Privacy > Groups.
Step 3: Select either “My Contacts” or “My Contacts Except…” to control who can add you to groups.

By limiting group additions to your contacts, you significantly reduce the chance of being added to spam groups. If someone outside your contacts wants to add you to a group, they’ll need to send you an invitation link instead.


Manage Business Messages

With the rise of WhatsApp Business, you might receive promotional messages from companies. While some of these may be welcome, others can be intrusive.

To unsubscribe from business messages:

Step 1: Open the chat with the business account.
Step 2: Look for an “Unsubscribe” option, usually at the bottom of the chat.
Step 3: If there’s no clear unsubscribe option, reply with “STOP” or “Unsubscribe”.

If you continue receiving unwanted messages:

Step 1: Tap and hold the chat.
Step 2: Select “Block” and then “Block and Report”.
Step 3: Choose a reason for reporting, such as “Spam” or “Unwanted messages”.

Reporting businesses that violate WhatsApp’s policies helps improve the platform for all users.


Adjust Privacy Settings

Fine-tuning your privacy settings can further protect you from potential spammers:

  • Hide your profile picture, status, and “About” info from non-contacts.
  • Disable read receipts to prevent spammers from knowing if you’ve seen their messages.
  • Turn off “Last Seen” to keep your online activity private.

To adjust these settings:

Step 1: Go to WhatsApp Settings > Privacy.
Step 2: Modify each setting according to your preferences, typically choosing “My Contacts” for most options.


Use the Report and Block Feature

For persistent spammers, WhatsApp’s report and block feature is your best defense.

Step 1: Open the chat with the spam account.
Step 2: Tap on the contact’s name at the top of the chat.
Step 3: Scroll down and tap “Report Contact”.
Step 4: Choose “Block and Report” to prevent future contact.

When you report a contact, WhatsApp receives the last few messages from that chat, which helps them identify and take action against spam accounts.

Implementing these measures will significantly reduce the amount of spam you encounter on WhatsApp. Remember to stay vigilant and never share personal information with unknown contacts. Regularly updating your WhatsApp app ensures you have access to the latest security features and improvements.


WhatsApp spam can be frustrating, but with these tools at your disposal, you can take control of your messaging experience. Keep your chats clean, your calls peaceful, and enjoy WhatsApp the way it was meant to be used – for genuine communication with friends and family.
