Kelantan was a state in the Federation of Malaya and was incorporated into Malaysia in 1963.
In 1909 stamps of the Federated Malay States were used, but from 1911 stamps were issued for Kelantan featuring the coat of arms of the sultanate. From 1948 the stamps issued were very similar to those of the other Malay States, the only difference being the inscription on the stamp, in this case Kelantan.
