11-Digit ID Numbers

Each Wiscard contains a unique 11-digit ID number that, in rare situations, is required for some library services.

The first 10 digits can be found under your name on your Wiscard. The 11th digit is the issue code and is located at the bottom right of your card.

Note that the issue code is based on the number of IDs that have been assigned to an individual (1st ID = 0, 2nd ID = 1, etc.) Only one ID – the most recently issued – will be valid at any time.
