Tanzania Telecommunications Corporation, formerly Tanzania Telecommunications Company Limited (TTCL), is the oldest and largest fixed line telecommunications company in Tanzania. The company comes forth from the former Tanzania Posts and Telecommunications Corporation in 1993. TTCL was wholly owned by the Government of Tanzania until the partial privatisation of the company on 23 February 2001.

The Tanzania Communications Regulatory Authority (TCRA), established by the TCRA Act No. 12 of 2003, is an independent Authority for the postal, broadcasting and electronic communications industries in the United Republic of Tanzania based in Mikocheni ward of Kinondoni District of Dar es Salaam Region. It merged the former Tanzania Communications Commission and the Tanzania Broadcasting Commission. The TCRA is accountable to the Communications and Technology Ministry. The Information Communication and Technology (ICT) sector reform in Tanzania is notable in that development was influenced by regional, political (national) and technological factors. Tanzania is one of the few African countries to liberalise the communications sector whereby the Converged Licensing Framework (CLF) is used as a key strategy, in terms of the Tanzania Communications Regulations. Since inception in 2003, the TCRA has issued a number of regulations to administer the sector, but still faces a number of challenges such as the roll-out of services to under-serviced rural areas.
