kwpn passports

I'm trying to find some information out for a friend, as she thought he was full warmblood so i was trying to find his pedigree online and cant find anything on any of them, I am quiet sure that he isn't full warmblood he look's like a gelderlander x hackney or something his 15 hands and moves quiet like a hackney. I am pretty sure that her passport doesn't have that stamp does that mean it isn't legitimate?
