Uber may lock or deactivate an account for several reasons related to safety, fraud, or community standards. Common triggers include fraudulent payment activity (such as using a stolen card or multiple chargebacks), having multiple accounts linked to the same device, or a history of low ratings and reported "unprofessional" behavior towards drivers. In 2026, Uber's automated systems are also highly sensitive to identity verification failures; if the app asks for a selfie and the face doesn't match the profile, or if there is suspicious login activity from an unknown location, the account will be locked instantly to prevent theft. If locked, you typically have to submit government ID through the "Help" section of the app to prove ownership and regain access.
