The Malayan Postal Union was organized in 1934 and initially covered the Straits Settlements and Federated Malay States. Stamps of the Straits Settlements together with issues for the individual States continued to be used, but Malayan Postal Union postage due stamps were introduced in 1936.

Following the end of the World War II the use of these postage dues spread throughout Malaya and to Singapore.
