Is this new? Never heard about it-or rather read.

Perhaps NMBS is itself not yet on the current with the new nrs? They do seem to check if a cover nr has in fact been released from stock.

@noa-je kan NMBS (=b-ral als je dat niet wist) bellen zoner dat nr-dat schellt ook 4€ kosten voor online maar kost wel een hoop aan belkosten.

Afh van welke rit (waarom niet ietsepietsie verder gedacht en meer info gegeven?) evt ook SNCF bellen.

@mcadv I fixed it by calling B-rail, but still would be nice if the number would work for future travelers :) 

Hi all, thanks for letting me know. It has been flagged with the relevant team and they are working on it at the moment. I will update you once its solved. 

Update: the Pass Cover number generator is working again.

Calling NS is cheaper, since NMBS’s phone number is rather expensive :/

And since NMBS charge 4€ per online booking (only online!), I only use their website to check availability.
