Your Buff OneCard ID is now your transit pass

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

Your Buff OneCard gives you access to RTD bus and rail routes, including routes to Denver International Airport.
