In places like banks or other customer care centers, tokens are issued to people and based on the token number, one is served by customer care. At some places, there are automatic displays displaying the current token number being served.
In case, if we have to ask some one at the reception about the current status, how'll we ask the question :-
"Excuse me, can you please let me know the latest token number which is being served (any other better word in place of served ?) ?"
I hope you understand the situation that I am trying to describe here.
