WhatsApp is the world’s most popular messaging app, with over 2.78 billion monthly active users as of 2025. But its massive user base also makes it a hotspot for spam, scams, and unwanted promotional messages. Whether fake job offers, lottery scams, phishing links, or random promotions, WhatsApp spam can quickly become annoying and even dangerous.
Fortunately, WhatsApp provides several built-in features to help users identify, block, and prevent spam messages. This guide offers only up-to-date information and explains exactly how you can stop spam on WhatsApp and protect your privacy in 2025.

WhatsApp has a feature called Channels as of 2024, allowing organizations to broadcast messages to large audiences. Ensure to follow verified channels only (marked with a green check badge).

Each WhatsApp update improves security and spam detection. Outdated versions may miss important privacy or detection features.
How to update:
Enable automatic updates in your device settings to stay secure.
Apps like Truecaller or Hiya may help identify spam numbers but come with privacy trade-offs.

These apps are more effective for spam calls, not messages, and should be used only if necessary.
Consider switching to a new number if your number receives too much spam due to public leaks or data exposure.

Your number might have been shared publicly or added to marketing lists. It can also happen if you join public groups where spammers collect contacts.
