If you have been issued a print-at-home E-ticket then you do not have to validate it.
Instead you just need to present it on board upon inspection.
Even if you are sure you know the correct name, it is a good idea to point to the town on the map anyway, just to be sure.
Slow Trav Note: One trip in England, Pauline and Steve purchased a train ticket for London from a small town train station.
Since my UK ticket can also be used at different times, I wonder if they follow the same principle.
Please be aware that you can only validate your tickets on the day of departure and no earlier.
Here is a photo of a validated/composted TGV ticket.
Just left of the barcode is a line reading “P Lyon 2106080926”.
This applies to the tickets of all of the following rail operators: SNCF, i DTGV, Eurostar, Deutsche Bahn, Renfe, Thello, Trenitalia, Italo, SNCB, NS, SBB, OUIGO, OUIBUS and ÖBB.
All SNCF print-at-station tickets must be validated before boarding the train.
