Hello Noavacheeck26
I see.
This error requires a closer look at your personal data entered. We are unable to help you through the SBB Community as, to protect your privacy, we are unable to treat personal data here.
I suggest you to contact the SBB Contact Center to have it sorted out: +41 51 225 78 56, 24/7, waiting times may occur.
It is also absolutely fine to wait with the purchase until the day when you arrive in Switzerland. You can purchase the subscriptions (abonnements) at the SBB travel center in Lausanne and have everything set up instantly in order to use the ticket right after purchase. There is no need to do it upfront online.
Kind regards,
Roland
