If you’re traveling on a Rail Pass (Eurail or country-specific Select Pass) then you have to purchase seat reservations separately. You can do this by going to the website where you purchased the Pass or from a rail station if you’re already in France. See the question above for details about Train Passes.
On the website look for wording like this: “Book a Reservation for your Pass” or on the purchase page: “Are you traveling on a rail pass?”
A FEW FINAL THOUGHTS:
- A reservation is a guaranteed seat on a specific train
- Rail carriers usually have a limited number of seats for travelers with a rail pass, so be sure to book as soon as possible
- You can generally book your reservation between 60-90 days before departure
- Not all ticket and reservations are ‘print @ home’ so you need to purchase sufficiently ahead of time to allow for ‘paper delivery’
- BTW all Rail Passes are issued in ‘paper’ (for now) so, there again, purchase early and leave sufficient time for delivery and … peace of mind
