At the end of the 19th century and in the early 20th century, many countries had post offices in foreign countries. The currency used could be either the local currency or that of the home country. Occupying military powers also established postal services in the occupied country.
As Great Britain occupied many countries during that period, there were many British Post Offices abroad...Only countries whose stamps we have in our collection, are mentioned in this article.
Post Offices in China
From 1842 – 1930 Britain had post offices in China. At first the letters were bagged in the various Chinese cities and sent to Hong Kong. They were cancelled B62, but after the 1860’s each office postmarked its own stamps. From 1862, stamps of Hong Kong were used, but after 1917, the Hong Kong stamps were overprinted China.
