Found out a great website that i would like to share, that allow you to check on a person, whether he / she is a real Datuk / Dato / Dato Seri / Tan Sri ?
Here is the link : http://www.istiadat.gov.my/index.php/component/semakanlantikanskp
All you need to do is to key in the name and click “Carian Pantas” button ( which means quick search). Under this search function, there are 3 additional options to choose : Peringkat (State), Tahun Kurniaan (Year awarded), Anugerah (grace)
