Puerto Rico uses the US Dollar (USD).
In Puerto Rico, cards work almost everywhere. Puerto Rico uses the US dollar and US card networks — no currency exchange or special cash planning needed.
Exchange rates at airport kiosks are usually the worst available — a local ATM after you land almost always gets you a better rate, and a small amount of cash exchanged in advance is only worth it for late-night arrivals.
Always choose the local currency when a card terminal or ATM in Puerto Rico asks — "dynamic currency conversion" into your home currency almost always carries a worse exchange rate.
Banks and airport kiosks quietly add 3–7% to every exchange through worse rates and fees. A Wise account converts your money at the real mid-market rate, holds 40+ currencies, and comes with a card that works at ATMs and terminals in Puerto Rico like a local one — usually the cheapest way for travelers to spend abroad.
