My experience bought number at JPJ in early of Aug.

Went to JPJ wangsa maju, there are few runner at downstairs But I straight go to first floor,take number and form then fill up with my personal details, attached with a cop. of IC and I have prepared almost 10 numbers to check. There should have a screen showing available number but unfortunately that was out of order.
The officer check for me the number one by one and tell me which number is available.
Waiting q for about 30mins, and only take about 3mins for the whole process. And it only take rm210.

Before went there I have check JPJ website the number terkini is WYU1XXX
And I looking for 3xx3 so lucky that i manage to get WYU 3xx3 at only RM210.
The time made booking for my car, those runner told me this kind number price about rm500-800.

The running number for both wilayah and selangor new alphabet  just started with 3 digits, easier for u to get ur desire number.

Above is my own experience for ur reference.

I was so lucky that the officer attend me check all 10 numbers to me patiently.
When i decided to take one of the number 3x33 and pass her cash, less than 30 seconds the receipt out.
My first experience truly great
