Tanganyika Postal Office Savings Bank (TPOSB) now Tanzania Commercial Bank came into being in 1925 when Tanganyika was under British Rule. It later became a Savings Bank under the then East African Post and Telecommunications which ceased to operate after the collapse of the East African Community. The Tanzania Posts & Telecommunications Corporation (TP&TC) came into being to cater for the Tanzanian market. TPB was formed from the now defunct TP&TC. TPB was established by the Tanzania Postal Bank Act No. 11 of 1991. On Monday the 29th of June 2015, the Parliament of the United Republic of Tanzania repealed the Act and on the 29th of March 2016 the bank was incorporated under the Companies Act (Cap 212) as TPB Bank PLC.
