Tanga Prepaid Franking

German East Africa

On 18 January 1916, a new system was introduced to reduced the usage of postage stamps, which were in short supply due to WWI.

Envelopes could be sent to Morogoro, Dar-es-Salaam, or Tanga to receive a prepaid franking mark. The mark consisted of the value and the official seal of the post office.

The envelopes could then be used at any local post office.
