Alameda County Library cards expire every three years. Updating your library card with current information is important so we can send you notifications on holds, items that are overdue or general library information such as events. We currently do not renew online. When logged into your account, there is a notification as to when your account will expire (up to 30 days in advance). This is your reminder that you need to update your account by going to your local library branch with identification and current address. This can be a California driver's license or ID, a bill with the current address, postmarked mail, etc.
Library cards that have expired are not usable until updated by staff.
