In order to support sustainable transportation options, CU provides a free taxi ride home in the event of an emergency or work schedule change (limited to CU Boulder and CU System faculty and staff).

How to Book Your Ride

You must have your staff/faculty Buff OneCard and your EcoPass to complete the ride.

  • Call 303-735-3568
  • Press 2 to be connected with corporate/private accounts and speak with an operator.
  • Provide the operator the CU Boulder account number BOU5302 and have your EcoPass or Buff OneCard number ready in case they ask for it.
  • Tell them where you are to be picked up and your destination.
  • When the cab arrives, you’ll need to show your Buff OneCard.
  • Upon reaching your destination, review and sign the trip voucher. The university will pay for your cab ride, but you must pay for any tip.
