What do you mean that you haven't received your pass? 

Because of the delivery delay too long, my family took me the pass in Belgium directly and sent it to me fast but it would be arrived in two days (it was supposed to arrive last friday…)

so i have a scan of it but not the pass at the moment 

I can't think that you are allowed to travel with a scanned copy of the pass. But @Claudi. can give you a 100% correct answer.

You can NOT travel with a scan or photo of a paper pass, it has to be printed on Railway imprinted paper and be with the proper cover to be valid.

Hello! Thank you for your question. Please accept my apology for the late response.

First of all, if you have a paper Pass, the cover number is printed on it but it is different than the order number starting with IN-8 digits.

Unfortunately no, the Pass is printed on value paper and it is not possible to travel with a copy of it.

I hope this helps!

Kind regards,

Annie
