You should receive an e-mail, although I don't know how long that can take.

I did receive an email confirming the order, and it said that my e-tickets should be attached to that email. But there was just an invoice attached to the email, not the actual e-tickets. 

Then contact customer support and mention that you'll be travelling the day after tomorrow.

Does anyone know if there’s a phone number I can call to have this addressed? The emails I received from customer service said they will try to respond within four days, which obviously is going to be an issue given I’m traveling in 36 hours!

There is no phone number. Requests are prioritised however, so if you've indicated your travel day, I suppose they make an effort to get back to you in time.

Hi Sam - did you resolve this? I have the same issue and I’m also travelling tomorrow. 

@Katie I did, I ended up going to Gare du Nord this morning. It took about 15 minutes, I went to the SNCF boutique and they printed my tickets for me. The reservation I made did go through, I just never received my tickets. If I’d known I just could have gone to the station early before my train and printed my tickets, but I wasn’t sure that the reservation actually went through. So you could conceivably just go to the station early tomorrow and get them to print your tickets…

NB: The Eurail support staff also responded to my email and attached my tickets to an email. But that was about 16 hours after I sent the request, and after I’d been to the station. If you’re traveling tomorrow I wouldn’t wait on the Eurail customer support to respond. A very hokey system. 

Good luck! 

Yeah the system is hokey but maybe blame 25%Eurail (still some bugs in the System) and

75% SNCF as they vanished the Interrail option from all their booking platforms :/

Means more reservation requests than usual by Eurail :/

Hi Sam, thanks so much for this! So helpful! I’ll try that.
