To contact Uber about a specific charge in 2026, the most effective method is using the "Activity" or "Help" section within the mobile app. Navigate to your "Activity" tab, select the specific trip that has the disputed charge, and scroll down to the "Help" section. From there, you can select options like "I was overcharged for this trip," "Review my toll or parking fee," or "I had a different issue with my charge." Uber's system will then prompt you to provide details, and in most cases, an automated review of the GPS data and fare estimate will resolve the issue within minutes. If you need to speak with a human or have a more complex billing error, you can use the "Message Us" feature in the Help center. While Uber does not have a public "customer service phone number" for general billing (the phone support is largely reserved for safety emergencies and Diamond-tier members), their in-app ticketing system is highly responsive. For "Uber One" subscription charges, you should navigate to "Member Benefits" and then "Manage Membership" to find the contact options for recurring billing inquiries.
