If there is an end date on your registration, it means you need to confirm your registration annually. You will receive an email each time it is time to confirm. End dates only appear on free registrations. This ensures that associations and landlords know that those registered are still interested in being on the list.
Note: If you do not renew your end date within the deadline, your registration will be deleted, and it will be assumed that you are no longer interested in being on the list.
