You may be using an audit number from an older license. You'll need to use the information on your most recently issued license in order to successfully add it to LA Wallet. If you need assistance obtaining your audit number, you can contact the Office of Motor Vehicles (OMV) for help at 225-925-6146 or by finding a local office here: https://offices.omv.la.gov/.
Additionally, a license/ID with an expiration date that has not passed does not indicate that the license/ID is your most recently issued credential from the OMV. Only when you renew your license/ID is when you receive a new expiration date on your credential. Any duplicate credentials issued to you will have the same expiration date.
