Make sure you are entering the same email address that the email was sent to, which may not necessarily be your current email address. The application is linked to the address the notice was sent to. You may also want to copy and paste the review code from your email notification into the AITAS system, rather than typing it. If you are still unable to access the application, contact the ATRRS Help Desk at (703) 695-2353/2060 or by email, firstname.lastname@example.org. Hours of Operation: Mon-Fri 0730 – 1730 Eastern Standard Time.
