Each student must have a Long Island University ID card. ID cards are needed in order to access LIU’S online library resources from off-site and are valid for one academic year. After one year, the bar code must be renewed. The photo-taking schedule for issuing ID cards and renewing barcodes is posted at the beginning of each semester. If a card must be replaced or a barcode renewed in mid-semester, please contact IT at (914) 831-2726.
