What is the currency in Puerto Rico?

The currency used in Puerto Rico is the US Dollar. Since Puerto Rico is a territory of the United States, it follows the same monetary system as the mainland states. This means that all transactions are conducted using the US Dollar, making it the official currency for both everyday purchases and larger financial transactions in Puerto Rico. This connection to the US financial system also allows residents and visitors to use their US currency in the territory without needing to exchange it for a different form of money. Other currencies mentioned do not apply as they are used in other countries and regions, which highlights the unique status of Puerto Rico within the framework of US territories.
