Getting Access to Argonne
Site access to Argonne National Laboratory is permitted only with an ID badge or a visitor pass. A visitor pass can be arranged:
     By phone: NE-CAT, 630-252-0689
      By email to: csalbego@anl.gov

The gate pass may be picked up at the Argonne Information Center located just outside the Main Gate Guard House off Cass Avenue. The Center is open M-F, 6:30a.m. -5:00p.m. CST. A pass may be left at the Guard House for pick up during times when the AIC is not open. A site access visitor pass alone does not permit a user unescorted access to the APS facility; either a temporary or permanent Cardkey® badge is needed for unescorted APS access.
