Without a Real ID-compliant license or ID card, Missourians may not be able to access certain federal facilities or board commercial flights within the United States, which can cause significant disruptions to travel plans and daily life. The Missouri Real ID Checklist provides clear guidance on the documents required to obtain a Real ID-compliant license or ID card.
