IMPORTANT! You can only modify your registration information before your application is processed. Once your registration is approved or rejected, you can no longer modify it. In such case, only the Conference Manager will be able to change your information on your behalf (you can contact directly the Conference Manager to request changes to your registration information). Alternatively, the Conference Manager can reset your registration status to “pending” so you can modify your registration.
- Go to the Indico home page: https://indico.un.org and search for your conference/event listed either under Highlights or in the Calendar.
- On your conference/event page, if you are not logged in yet, click on the Login button at the top right corner of the window.
- Log in using your e-mail and password.
- On the conference/event registration page, click on Modify or on Registration to modify your registration information form.
- Click on Modify.
To obtain information on the status of your registration/approval, please contact the event organizer(s). The contact information of the event organizer(s) is listed on the event page in the menu bar on the left (usually under Contact, see screenshot below).

In this case, check one of the following:
- Check your spam/junk folder for the confirmation e-mail.
- Check whether or not you have indeed completed registration for the event in question. Go to the event in question, click on the Registration link on the left-side menu. If you have already registered, you will see your registration data. If not registered and the registration period is open, you will see the Register now link (see screenshot below).

IMPORTANT! The creation of an account in Indico does not mean you are registered for an event. Registering for an event requires the filling-in of a registration form. Events open for registration will have a Register now button which launches the registration form.
