Singapore was originally part of the Straits Settlements and used their stamps until 1946. The first stamps of Singapore were issued on 1 September 1948 and were stamps of the Straits Settlements inscribed SINGAPORE at the foot

A British Crown Colony until 1957 the stamps were issued for the omnibus series of the Royal Silver Wedding (1948), 75th Anniversary of the Universal Postal Union (1949) and the Coronation of Queen Elizabeth II (1953)

From 1 August 1958 Singapore became self-governing, within the Federation of Malaya, as the State of Singapore and used the stamps of the Federation concurrently with those marked Singapore. Five sets of commemorative stamps were issued in this period, to mark the New Constitution in 1959 and National Days in 1960, 1961, 1962 and 1963. All were inscribed State of Singapore. In addition a long definitive set marked simply Singapore was issued from 1962 onward

In 16 September 1963 Singapore merged with the Federation of Malaya along with Sabah and Sarawak to form the Federation of Malaysia then, on 9 August 1965, Singapore seceded from the Federation of Malaysia to become an independent republic within the British Commonwealth. A set of stamps were issued in 1966 to commemorate the first anniversary of independence marked Republic of Singapore but all later stamps to this day have been marked just Singapore
