 OFFICIAL AND SECURE - Operated by Kwasilva under ZARTSA certification — every action is written to the official vehicle register of Zanzibar - You are identified by your National ID and confirm each action with a one-time code sent to your phone - Fixed, transparent fees — you always see the full amount before you pay
 WHO IT IS FOR Private vehicle owners, commercial and public transport operators, and licensed agents acting on behalf of owners in Zanzibar.
