Postal codes in Malaysia, usually referred to as postcodes (Malay: poskod), are five digit numeric.
The first two digits of the postcode denote the state or federal territory (e.g. 42000 Port Klang, Selangor). However, postcode area boundaries may cross state borders, as areas near to state borders may be served by post offices located in another state, and therefore use postcodes of the assigned post offices.
