Having an Illinois DMV REAL ID Checklist is important because it provides a comprehensive list of required documents and information that must be presented when applying for a REAL ID. The REAL ID Act was passed in 2005 by the US Department of Homeland Security to establish minimum security standards for driver’s licenses and identification cards, which are needed to access certain federal services. The Illinois DMV REAL ID Checklist ensures that individuals applying for a REAL ID have all the required documents and information available to complete the application process.
