Located in Southern Arabia, Aden was a former British colony and protectorate. Aden used the stamps of India until 1937.
The first post office in Aden opened in 1839 in what was known as the Crater district. While no stamps were initially available, after the
post office was placed under the Bombay Postal Circle, issues of the Ża. and 1a. stamps were put on sale.
Image Count: 29. Aden has 31 stamps with a kings
