When you arrive at the test center, you'll be required to show acceptable identification before being admitted to the test. The ID you present, including any required signatures, must be original, not a photocopy or reproduction. Only the following forms of identification are acceptable. If it's not on this list, it's not acceptable, and you will not be admitted to the test.
Remember, you will also need to carry your ACT ID for the examination. The ACT ID is an eight-digit identification number beginning with a dash. If you’re confused about how to find ACT ID, don’t hesitate to call ACT test support for assistance. It’s usually located at the bottom and top of the student report on the admission ticket.
