As many have asked before, I need my pass cover number for my mobile pass. This is urgent as travel is for tomorrow. There are seats available but it requires my pass cover number. The Eurail interface for reserving seats is bugged out basically all the time so I can’t book them there. I have already tried calling SNCF but as I am booking from London to Paris on Eurostar they said they cannot help me. Please any help is appreciated. I have submitted a form already but fear it won’t be responded to in anywhere near enough time.
