Lookup your Illinois doctor’s license, at this elicense online website. Select Medical Board to start your search for physician medical license. Look up doctor license expiration date for both MDs and DOs. See if there is a discipline indicator or not. The new site provides limited information. No longer can you find education, training, and board certification; nor the optional hospital affiliations, health insurance, honors & awards, community activities, and publications. Site by IL state Division of Financial and Professional Regulation, updated 2022.
