Yes, Uber uses SMS text messaging as a primary communication channel for account security and real-time trip coordination. When you first sign up or log in from a new device, Uber sends a verification code via text to ensure you are the account owner. Once a ride is in progress, the app facilitates "masked" text messaging between you and your driver; this allows you to coordinate pickup locations or provide gate codes without either party seeing the other's actual phone number. Additionally, Uber may send promotional texts or "push-to-SMS" notifications if you have opted in or if the app is not currently active on your phone. In 2026, while much of this has moved toward in-app notifications, SMS remains a vital "fallback" system to ensure communication works even in areas with poor data connectivity. You can manage these preferences in the "Communication" section of the Uber app settings if you wish to reduce the number of texts you receive.
