@Magdalena Has helped on this before.

Also question regarding to this same thing; Is is possible to get pass cover number before I activate my mobile ticket? I would like to get it before I start my Interrail if possible.

Depending on where you book and what trains the nr is not always needed.

Yes, you can get it beforehand for exactly that reason

There is-since this overwhelming 50% sale-an enormous backlog of all types of complaints/questions/puzzles tc-=not helped as thus all inpatient people start repeating ending mails etc clogging up the system.

Hi @Rachel Leonard,

I sent you a private message :) 

Hi @Bell_pepper,

As long as your pass is valid, you can be entitled to getting a pass cover number if you need it. As @mcadv mentioned, depending on through where you decide to make reservations, you might not need a pass cover number. 

Cheers :)

Hi @Magdalena :

Wwe are a family of 5 members who is struggling to make a reservation for our train from Bordeaux to Strasbourg. The interrail app doesn’t provide places and we need a pass cover number (which we don´t really know what it is) to reserve at travel.b-europe.com. That is the beginning of the trip, and the rest is already planned! 

Can you please provide us with the pass cover numbers we need?

Thank you

@Xiomara Gezuraga
