All states of Malaysia issue stamps, mainly definitive stamps of the same design, but with their respective state names.
Malaysia started issuing stamps after independence from the United Kingdom on 31 August 1957. These stamps bore the title of Malayan Federation until 9 August 1963 when Sabah, Sarawak and Singapore merged with Malaya to form Malaysia.
Singapore became independent from Malaysia in 1965.
