WhatsApp has started testing its new Scam Alert feature with select Android beta users. The new security feature can warn users when a message from an unknown contact shows signs of a possible scam.
The WhatsApp Scam Alert feature uses an on-device machine learning model to check suspicious messages. This means the detection happens directly on the user’s smartphone instead of sending the message content to Meta for checking.
For now, the feature is available only to a limited number of beta users. WhatsApp has not announced when it will become available to everyone.
WhatsApp Scam Alert Feature Enters Beta Testing
WhatsApp first shared details about Scam Alert earlier in August. Now, the feature has started appearing for some Android beta testers.
According to reports, select users running recent WhatsApp beta versions for Android can access the feature. Since the rollout is limited, installing a beta version does not necessarily mean every user will immediately receive Scam Alert.
WhatsApp is expected to continue testing the feature and improving its accuracy before considering a wider release.
How WhatsApp Scam Alert Works
Scam Alert mainly focuses on messages coming from people who are not saved in the user’s contacts.
Once a user enables the feature, WhatsApp downloads a machine learning model to the smartphone. This model looks at conversational patterns and language signals to determine whether an incoming message from a non-contact could be part of a scam.
If the system finds signs of a possible scam, WhatsApp displays a warning inside the conversation.
The warning is visible only to the person receiving the message. The sender will not know that WhatsApp has flagged the conversation.
Users can then decide what they want to do with the suspicious chat.

Users Can Block, Report or Trust the Sender
WhatsApp does not automatically block a conversation just because its system detects something suspicious.
Instead, users remain in control.
If WhatsApp shows a Scam Alert, the user can choose to block or report the account. They can also continue the conversation if they believe the message is genuine.
In case WhatsApp incorrectly identifies a trusted conversation, users can mark that chat as trusted. The feature will then stop showing Scam Alert warnings for that conversation.
This approach can be useful because a message from an unknown number is not always a scam. It could also come from a delivery person, business, colleague or someone the user knows but has not saved in their contacts.
WhatsApp Scam Detection Happens on the Device
Privacy is one of the most important parts of the new WhatsApp Scam Alert feature.
According to Meta, the machine learning model performs the scam classification directly on the user’s device. The content of messages does not leave the smartphone for this detection.
WhatsApp also says that detecting a possible scam does not automatically report the conversation to WhatsApp, Meta or another third party.
A message can reach WhatsApp through the normal reporting process only if the user chooses to report the conversation.
This allows WhatsApp to add scam detection while keeping its end-to-end encryption protections in place.
WhatsApp Scam Alert Is an Optional Feature
Another important point is that Scam Alert is optional.
Users can decide whether they want to enable it. When enabled, the machine learning model runs locally on the device to check incoming messages from non-contacts for possible scam patterns.
WhatsApp has designed the feature to give users additional information before they decide whether to continue interacting with an unknown sender.
Users can also turn the feature off if they no longer want to use it.
Why WhatsApp Scam Alert Could Be Useful
Scammers regularly use messaging platforms to contact people with fake offers, impersonation attempts, suspicious payment requests and other types of fraud.
In many cases, these messages come from numbers that users have never contacted before.
The WhatsApp Scam Alert feature could provide an additional warning before someone replies to a suspicious message or follows instructions from an unknown sender.
However, users should still check unknown messages carefully. No automated system can guarantee that it will identify every scam.
Users should avoid sharing OTPs, passwords, banking details or other sensitive information with unknown people.
Will WhatsApp Read Your Messages for Scam Detection?
WhatsApp says message content does not leave the user’s device for Scam Alert classification.
Instead, the downloaded machine learning model performs the detection locally on the smartphone.
The feature is also designed to work alongside WhatsApp’s existing end-to-end encryption.
If a user decides to report a suspicious account, however, information can be shared with WhatsApp through its existing user-reporting process.
When Will WhatsApp Scam Alert Be Available to Everyone?
WhatsApp has not announced an official date for the wider rollout of Scam Alert.
Currently, the WhatsApp Scam Alert feature is being tested through a limited beta rollout. Therefore, most regular WhatsApp users may not see the option on their smartphones yet.
The beta testing period should allow WhatsApp to study how well the feature identifies scams and where it could produce incorrect warnings.
According to Meta Engineering, the Scam Alert feature uses an on-device machine learning model to identify possible scam messages while keeping the detection process on the user’s smartphone.
Depending on the results, WhatsApp could make changes before expanding the feature to more users.
