WhatsApp is enhancing user security by introducing a new feature that alerts users before they initiate conversations with unfamiliar phone numbers. This update, available on both Android and iOS platforms, aims to curb potential scams by providing users with critical information about unknown contacts.
When a user attempts to start a chat with an unsaved number, WhatsApp now displays a warning screen. This screen reveals the country where the number is registered, indicates whether the number is saved in the user’s contacts, and shows any mutual groups shared with the number. This proactive measure encourages users to reconsider engaging with unknown contacts, thereby reducing the risk of falling victim to scams.
Unlike previous security features that activate during interactions, this pre-chat warning intervenes at the earliest stage—before any messages are exchanged. By presenting this information upfront, WhatsApp empowers users to make informed decisions about initiating conversations with unfamiliar numbers.
In August 2025, Meta, WhatsApp’s parent company, announced plans to implement new protections against messaging scams. This pre-chat warning feature is a tangible realization of that commitment, addressing the common tactic used by scammers who exploit the trust associated with new numbers. Messages like “Hey, it’s me, I changed my number” can now be met with increased scrutiny, thanks to this new warning system.
Users encountering this warning are advised to:
- Carefully review the displayed details, especially the registered country of the phone number.
- Verify the contact’s identity through alternative channels, such as calling their previously known number.
- Consult mutual contacts if the person claims to be someone familiar.
- Cancel the chat if any doubts arise, as proceeding could lead to potential risks.
It’s important to note that while this system adds a significant layer of security, it is not infallible. If a scammer’s number is already saved in a user’s contacts, the warning may not trigger. Conversely, legitimate contacts who have changed their phone numbers might also prompt this alert. WhatsApp has not disclosed the specific criteria that activate the warning, though factors like cross-border number registration appear to play a role.
The rollout of this pre-chat trust warning is currently underway globally for both iOS and Android users. This feature represents a proactive step in WhatsApp’s ongoing efforts to enhance user safety and combat digital fraud.
By implementing this preemptive warning system, WhatsApp is taking a significant step toward safeguarding its users from potential scams. This feature not only raises awareness but also encourages users to exercise caution when interacting with unknown contacts. As digital communication continues to evolve, such proactive measures are essential in maintaining user trust and security.
