AC Transit EasyPass Issue Resolved

The Clipper card readers on the DB lines have been updated and the issue has been resolved. Please tag on to all DB and AC Transit buses with your Stanford-issued Clipper Card.

AC Transit EasyPass

AC Transit's EasyPass is available to eligible university employees, SLAC employees, and postdoctoral scholars who reside in the East Bay. It provides unlimited travel on all AC Transit services, both local and Transbay (including the Dumbarton Express), and is valid for the entire calendar year, seven days a week. Stanford purchased these passes from AC Transit primarily for eligible East Bay residents who commute to Stanford; however, their use is not restricted as long as you reside in AC Transit’s service area.
