What is a PIN?
• For security reasons, the SDSU Library requires you to have a PIN (personal identification number). • A Library PIN is different from your SDSU identification number and your WebPortal/Blackboard password. • Your PIN is used to access and use a variety of electronic library services including Circuit and LINK+.
A PIN is your Personal Identification Number. It is the unique number that is given to you when you purchase your card. It is our way of identifying your account and placing appropriate billing. If you purchased your Global Papa phone card online, your PIN will be e-mailed to you with the access numbers. If you purchased your card in the store, scratch off the silver strip on the back and you will see your PIN.
