If a message on WhatsApp looks like a scam, your phone will now tell you before you answer. Meta is rolling out an optional feature called Scam Alert that checks incoming messages on your device and drops a warning inside the chat when it reads one as a likely con. From there you decide whether to block the person, report them, or carry on. The feature is in a limited beta for now, so not every account has it yet.

## The Warning Shows Only to You

When the on-device model flags a message, the alert appears right in the conversation, and only on your screen. The other person gets no signal that anything tripped. You have three moves: block them, report them, or keep talking as normal. If you think the warning is wrong, you can mark the chat as trusted. The warning disappears and Scam Alert will not flag that chat again. It is there for the false positives you will hit, a supplier, a distant relative, a new number that is perfectly legitimate but reads as unusual to the model.

## Nothing Leaves Your Phone Unless You Choose to Share Your Messages

The detection runs on your phone, using machine learning. Meta says that when scam detection is on, "no message content leaves the user device for classification," and that nothing is "auto-reported to WhatsApp, Meta, or anyone else." The checking happens on your handset, not on a server. There is one place where you can send data outward, and it is opt-in. When you mark a chat as trusted, you can choose to share the last 5 received messages with WhatsApp to help improve the feature's accuracy. You do not have to. Skip that step and the messages stay on your phone. Scam Alert is optional to begin with, and you can turn it off at any time.

## Scams Cost $2.1 Billion on Social Media Last Year

The US Federal Trade Commission reported that [social media scams reached $2.1 billion in reported losses in 2025](https://www.ftc.gov/news-events/news/press-releases/2026/04/new-ftc-data-show-people-have-lost-billions-social-media-scams), with nearly 30% of people who reported losing money to a scam saying it started on social media, an eightfold rise since 2020. People reported losing more money to scams that started on Facebook than on any other platform, with WhatsApp and Instagram a distant second and third.

On WhatsApp specifically, victims reported losing $425 million, according to the FTC data as reported by The Verge. The common setups are wire-transfer fraud and "pig butchering" investment scams, where a stranger builds trust over weeks before steering you toward a fake trade. WhatsApp has more than 3 billion users, which is the scale Scam Alert is meant to cover. Earlier this year Meta added scam detection for device-linking requests, aimed at attackers trying to hijack an account, and the message warning is the next piece.
