You get a message from someone claiming to be your bank, a recruiter, or a familiar brand. The username looks convincing, but something feels off. UsernameCheck gives you a place to check before you reply, send money, or open a link. Search WhatsApp and Instagram usernames, see community reports and report categories, report suspicious accounts anonymously, and share results with others. It will not make the decision for you, but it can help you pause and make a better call.
