the first letter of kazakhstani license plates indicate where the car is from.
A is for almaty city
B is for almaty province (but not almaty the city)
D is for aktobe province
H is for zhambyl province (which includes taraz)
X is for south kazakhstan
i've also seen C, N and S, but i don't know where they are from yet.
and for some reason kazakhstani license plates use latin characters, even though boththe russian and kazakh languages use cyrillic.
