HOMER Library Barcode
- In most cases, the barcode number is your USC ID + 4-digit security code (see example above).
- If this does not work, try entering only your 10-digit USC ID number, which appears on the front of the card (circled above)
- If the USC Libraries have issued you a card with a barcode label beginning 21275 _ _ _ _ _ _ _ _ _, enter this full 14-digit number.
