Campus Cards

Your Buff OneCard is your key to all kinds of services and events here at CU. It is your official university identification and as a student or employee you are required to carry it with you whenever you are on campus. Your Buff OneCard should be presented upon the request of any university official. As a regularly enrolled student or a regularly employed staff person, your first card is free. When obtaining your first card, please bring a driver's license or government issued photo ID to verify your identity. For more information on what the card can do for you, click here.

Guests, contractors and temporary employees may need a card to access certain services on campus. For more information on how to obtain a guest card, click here.
