Yes it is fine. Nobody complained about problems. And the cover number generator is an official tool of Eurail.

If I am not wrong, the pass cober number will not be printed on the reservation.

Absolutely no problem, the number generated should have the format Ixxxxxxxx for Interail passes. Strangely you put the pass number in to b-europe to make the reservation, the reservation itself does not link to a specific pass, just your name.

I assume the need for a number was introduced when there were only paper passes which use the 8 number format, whilst the mobile passes use a simpler format. The message is something that is poorly worded, in reality it should be reworded to point out the number required is immediately usable from a paper pass but a mobile pass needs a number created by this tool. Until a few weeks ago you had to contact Interrail for a number, but the new tools mean we can do it for ourself,

So go ahead and make your reservations with the number generated by the new tool.

Wonderful!

Thanks for your kind prompt help!

God bless

I have one query about this: The pass cover number generated actually had E as starting Alphabet not I

Is that okay?

Yes because you are from outside Europe and have an Eurail Pass. For Europeans the same Pass is called Interrail.

Great, thanks so much Angelo!!!

This added question is mostly there to prevent some people to buy reduced ´tickets ´ as they could cheat without having the correct pass. For the same reason in some other countries the RES-only are so hard to get-railways are not charitable institutions. But as I did this trip in late aug I cannot really remember to also even have to show my pass, having also booked online via b-rail

Trust me, whilst you need your reservation to even get access to the departure lounge, they diligently checked my pass as well on the train last week. Obviously they are aware of those who risk it and falsely claim they have a pass .
