Registration and the Guest Information System

All non-U.S. citizens, and most U.S. citizens — except as noted below* — must enter their information into the BNL Guest Information System (GIS) for site access.

Once you have completed this form, you will automatically receive e-mails to provide further instructions prior to your arrival. Upon initially completing the online form, you will receive an e-mail giving you a GR Number; this number is only a tracking number. This is not your final Identification Number. When your GIS submission is fully approved, you will receive another e-mail indicating that you have been approved and you will receive your final identification number, called a Guest Number.

If you have registered and received a Guest Number for a previous visit, please use that Guest Number and check or renew your status via Guest Central.
