In order to gain access to an REC, you will be required to provide a valid driver's license or identification card from a state that meets the Act's minimum standards OR by providing some form of currently valid federal identification (passport, TWIC, MMC, etc.). Failure to provide proof of acceptable identification will prevent you from entering the REC to conduct business which may affect your credential and/or application.
