If you are an active Gympass member, you will automatically have a Gympass ID. You can easily find it in the Gympass app and website:
In the app, the Gympass ID appears at the top of the screen, next to your photo and underneath your username. On the website, all you have to do is head into Settings and check the Gympass ID in the menu on the left-hand side.
About the Gympass ID:
The Gympass ID is the number that you need to give to the gym to identify yourself as a Gympass user - for your first registration or in case you have any issues checking in.
Keep in mind that some gyms may ask you to provide your personal information at reception — including your Gympass ID - on your first visit.
