The Imperial British East Africa Company was the first company holding a Royal Charter allowing operation of a postal system, for both local and international mail, to use their company name on their stamps. They were also the first to create a series of surcharged stamps with authorizing initials. Both of these led to the adoption of these practices by other countries such as the British South Africa Company and the Mozambique Company in 1892 and the surcharged Uganda typewritten stamps in 1895.
