The official local currency on Zanzibar is the Tanzanian Shilling, denoted by its ISO-4217-Code: TZS. While USD is widely accepted across the island(s), it’s essential to keep a few crucial details in mind to ensure a smooth financial experience during your trip:

• USD Bills Pre-2006: Avoid Inconvenience – It’s important to note that local businesses might not accept USD bills issued before 2006 or might give a poor rate. To ensure hassle-free transactions, it’s best to carry USD bills with later issuance dates.
• Better Exchange Rates for Larger USD Bills: If you plan to use USD for transactions, consider carrying 50 USD bills or higher. These larger denominations usually offer better exchange rates compared to smaller bills, maximizing the value of your currency.
• Always Verify the Exchange Rate and Change: When dealing with currency exchange, whether converting USD to TZS or making purchases with USD, always verify the current exchange rate to ensure you receive fair value for your money. Similarly, double-check the change you receive to avoid any discrepancies.
