Procedure is simple, depend on what kind of number u want if it's bidded then u hv to wait next alphabet already, if it's not you can buy through counter..

If u don't mind older number, u can request to go into bilik pengarah or pegawai to see some older plate given up by other people.. got some good one in there.. same price...

Usually u just walk into jpj fill form with photocopy ic and wait yr queue then go ask the counter lady. Dont havr baru masuk bilik
