TZ — Tanzania

Tanzania is an East African country home to Mount Kilimanjaro (Africa's highest peak), the Serengeti, and the island of Zanzibar. Dodoma is the official capital, though Dar es Salaam remains the largest city and de facto economic capital. Tanzania was formed from the union of Tanganyika and Zanzibar in 1964. The Tanzanian Shilling (TZS) is the national currency. For developers, the TZ country code maps to sw-TZ for Swahili (the primary national language) and en-TZ for English. The .tz domain serves Tanzania's growing digital ecosystem, and +255 is the dialing code. Swahili is one of the most widely spoken African languages with over 100 million speakers across East Africa, making sw-TZ one of the most important African locales for developers. Tanzania's mobile money ecosystem is significant, with M-Pesa and other platforms widely adopted. Tanzania's dual-capital situation requires accurate representation in address and location databases.
