What about non-DHS federal entities? What types of licenses and identification cards will they accept for access purposes?
Since federal agencies can set their own minimum requirements for security access, they can decide to not accept non-compliant cards before the deadline of October 1, 2020. In order to make sure you have the correct documents needed, it's important to contact the agency you plan on visiting before you go.
Keep in mind, the REAL ID act only applies when someone presents a state issued license or ID for official purposes. While a REAL ID card might not be required for things like driving, voting or banking, it's a good idea to check with the agency to see their specific requirements.
