I have forgotten or do not know my membership number?You need your membership number to log in to the STFs app where you have access to your membership card.
You find your membership number on your physical membership card or on the latest bill. If you registered an e-mail address when you became a member you can fill out this form and we will e-mail you your membership number. If you have not registered an e-mailadress please contact our member service.
