SnT2027 | Registration and VIC Access
Participation in the CTBT Science and Technology Conference 2027 (SnT2027) involves a two-step registration process for participants attending in person.
Please follow the steps below to ensure that your Conference participation and access to the Vienna International Centre (VIC) are properly arranged.
STEP 1 — Conference Registration and Approval
Apply to participate in SnT2027
All prospective participants must first submit their application through the official SnT2027 Conference registration platform. Applications will be reviewed through the Conference registration process, and applicants will be notified of their registration status.
Please note: Submission of an application does not automatically confirm participation in SnT2027.
STEP 2 — VIC Access Registration
For approved in-person participants only
Once participation in SnT2027 has been approved, participants attending in person will subsequently receive a link to Indico.UN to complete the registration required for VIC security accreditation and issuance of a VIC Access Card / Grounds Pass.
This second step is intended exclusively for participants whose Conference registration has already been approved.
Important: Registration on Indico.UN does not constitute an application to participate in SnT2027. Only participants approved through the official Conference registration process and whose details have been provided for VIC accreditation will be eligible for approval on Indico.UN.
In Summary:
Step 1: Apply for and obtain approval to participate in SnT2027 by registering on the main page
Step 2: If attending in person, participants will receive a link to complete the Indico.UN registration for VIC access accreditation.
