My 4Days

Changes to My 4Days will no longer be processed from 27 November 2023, 17.00 hrs CET.

Within a few weeks we will switch to a new system that allows us to serve you even better. A new participant portal will then replace the My 4Days environment. We need some time to ensure a smooth transition. For you as the user, it means that changes made after 17.00 hrs CET on 27 November will not be processed.

Do you have any questions or would you like to request your registration number? Please contact our Service Desk at info@4daagse.nl.

More information will follow via our website in a few weeks. Thank you for your patience!
