Cal Poly Library Cards

Library User Number

To register in PolyCAT, you have to provide your last name and library number.
My PolyCat is available to current Cal Poly students, staff and faculty. In My PolyCat, you may view items you have checked out, renew your items online, read messages from the library (items requested and ready for pick up, et cetera), and save your PolyCat searches.

Cards issued after July 10, 2012 have the library number printed on the back side.

Cards printed before July 10, 2012 have a different design, and show the library number in the front below the user photo. These cards remain valid, so unless they are worn out or broken, there is no need to replace them.
