Your library barcode is the 10 digit number on your USC ID card + the 4 digits on the back of your ID card. Write out the number with no spaces in between:

  • If this does not work, try entering only your 10-digit USC ID number, which appears on the front of the card.
  • If the USC Libraries have issued you a card with a barcode label that begins with 21275 _ _ _ _ _ _ _ _ _, enter this full 14-digit number.
  • If you are still having problems, contact the Doheny Library Circulation Desk: in person, or call (213) 740-2924, or email:
