FAQ German Rail Pass
How do I get my online ticket after booking?

The ticket is immediately available in pdf format for download. The link to download your ticket will be displayed after completing the booking process and also sent via e-mail. Please print out the online ticket on a full A4 page for control on the train. Please make sure when printing your ticket that the images are not suppressed, otherwise it may be invalid.

Is my ticket valid if I display it on my smartphone?

No, tickets purchased through dbregio-shop.de are only valid in printed (paper) form.

How do I refund or exchange my GRP?

You cannot. There is no exchange or refund on any GRP. Therefore we strongly recommend to double-check the validity date entered before purchasing the pass.
