To show proof of age, a photo ID, such as a driver’s license or passport works best. You can also use a birth certificate or any other document that has your name and birthdate printed on it. You could also use a letter from your doctor, medical record, discharge paperwork, or other document with this information. You will not have to show proof of citizenship or U.S. residency status.
