Starting on Sept. 1, the Buff OneCard ID will be used as a transit pass for all enrolled students and benefited employees. Boulder is no longer issuing CollegePasses or EcoPasses. If you have further questions or encounter problems with your card, contact buspass@colorado.edu.

Don’t forget: Your Buff OneCard gives you access to RTD bus and rail routes, including routes to Denver International Airport. Get more bus route and and bus pass information.
