[citation needed] Definitive British stamps were overprinted "M.E.F."
They were available in Cyrenaica, Eritrea, Ethiopia, and Somalia, Tripolitania as well as in the Dodecanese islands in the Aegean.
In 1950, the British government declared that the remaining overprinted stamps were valid for postage throughout the UK, and so many of the surviving stamps have British inland rather than foreign postmarks.
The East Africa Forces in Italian Somalia also received British stamps, but overprinted "E.A.F."
From 1948 on, the military administrations in Eritrea, Somalia, and Tripolitania used their own overprints.
