|The use of ATINS in ULS is being phased out. As of December 3, 2001, ATINS will no longer be assigned, and you will only be able to use your current ATIN(s) on the ULS/TIN login screen during a short transitional period. Applicants that previously used ATINS, such as Amateur Clubs and foreign amateurs, must now be registered in CORES. Follow the "Register Now" link in ULS to access CORES registration. Complete the administrative information required, choose the appropriate exempt category, and provide your new FRN on all applications.
