While the official currency of Jordan is the Jordanian Dinar (JOD), US Dollars (USD) are widely recognized and often accepted in major tourist areas, luxury hotels, and for large purchases like guided tours or high-end souvenirs in 2026. However, paying in USD is generally not recommended for day-to-day transactions. When you pay in dollars, merchants often apply an unfavorable exchange rate, and you will almost certainly receive your change in Dinars. In local markets (souqs), smaller restaurants, and for taxi fares, you will need the local currency. The Dinar is currently pegged to the US Dollar at a rate of approximately 1 JOD = 1.41 USD (or 1 USD = 0.709 JOD). In 2026, the most cost-effective strategy is to withdraw Dinars from an ATM upon arrival or use a credit card with no foreign transaction fees. While you can use dollars in a pinch at places like Petra or Wadi Rum, having local currency ensures you are paying the correct price and avoids the "tourist tax" associated with poor on-the-spot exchange rates.
