Site Access

Argonne National Laboratory is a controlled-access facility. You will need a visitor’s pass or a user badge to enter the Argonne campus.

You must notify us of your visit in advance; see the steps below. When you arrive, you will be asked to present your identification documents, and then you will be given your pass or badge. You can then come and go freely during the period for which your pass or badge is valid. You must wear your pass or badge visibly at all times while on site.

Important: Please ensure that you have received all necessary confirmations from the User Office before you travel to Argonne.
