WhatsApp has begun rolling out a new security feature designed to help users identify potential scams before a conversation even begins.

The update introduces pre-chat trust warnings for messages received from unknown numbers, providing users with additional context before they decide whether to engage with a sender.

The feature is now rolling out globally on both Android and iOS devices.

A Pause Before the Conversation Starts

Instead of opening a chat immediately, WhatsApp will now display a warning screen when a message arrives from a number that is not saved in a user's contacts.

The screen includes key information about the sender, including the country where the phone number is registered, whether both users share any mutual groups, and confirmation that the number is not saved in the recipient's address book.

Users can then choose whether to continue into the conversation or exit the chat altogether.

According to WhatsApp, rejecting the interaction does not notify the sender, ensuring that users can make a decision privately.

Why It Matters

The feature is aimed at tackling impersonation scams that have become increasingly common across messaging platforms.

Fraudsters often rely on urgency and familiarity, using tactics such as claiming to be a relative with a new phone number or posing as a trusted contact to convince victims to respond before verifying their identity.

By introducing a pause before the conversation begins, WhatsApp hopes to give users enough context to identify suspicious messages before any interaction takes place.

For countries such as Nigeria, where messaging apps have become a primary channel for both personal and business communication, the update could help reduce exposure to some of the most common forms of mobile fraud.



Part of a Broader Security Push

The trust warning feature forms part of a wider effort by Meta to strengthen safety across WhatsApp.

The company has recently introduced additional tools designed to limit spam, block suspicious activity and provide users with greater control over who can contact them.

While cybersecurity experts have welcomed the move, they note that the feature is not foolproof. Scammers using local phone numbers or compromised accounts may still appear legitimate.

Even so, the update reflects a growing shift in online safety, one that focuses less on analysing message content and more on providing users with the information needed to make informed decisions before engaging.
