PSU ID Number
The PSU ID number is a 9-digit number that is unique to each student, faculty, or staff member. The Gorilla Card is issued with your PSU ID number printed on the front. You will need this number to access many of the systems and services at PSU, including GUS. You must use your 9-digit ID Number to login to your Gorilla Card Online account.  You may not be required to enter the leading zeros in other online systems like GUS and many other systems on campus.

PSU Status
Most cards will list a status of Student, Faculty or Staff.

Card Number (ISO Number)

The 16-digit number printed on the front of your card is also encoded on the magnetic stripe on the back of your card. It is an identification number used when scanning your card for services and activities on campus. This number is also used to attach your Commerce Bank Gorilla Checking account to your Gorilla Card. If a card must be replaced, the cardholder will be issued a new Card Number and the old number will be deactivated. Once a Card  Number has been deactivated, it cannot be used again.

Magnetic Stripe

The magnetic stripe is encoded with three “tracks” of information. Track 1 is formatted based on the ABA (American Banking Association) standard and is used for ATM and debit card access to your Gorilla Checking account from Commerce Bank. Track 2 is encoded with your 16-digit ISO card number and is used when your card is "swiped" in a reader, eliminating slow keyboard input of your 16-digit number. Track 3 is encoded for use in future applications such as door access.
