When you verify your identity, that verification photos are effective for one year, for all courses. If you enroll in the verified track for another course, you pay for that course’s certificate, but you do not have to verify your identify again.
Note: The verification expiration date does not impact the time you have to finish a course. To earn a certificate in your course you will need to reach a passing score before the course end date.
Once your photos expire you may simply resubmit new photos from your dashboard to cover future courses.
