Yes, if you are a citizen of the United States, Canada, the UK, or most other countries, you absolutely need a valid passport to visit Punta Cana in the Dominican Republic. It is a sovereign foreign nation, so domestic IDs or birth certificates are not sufficient for entry. Your passport should be valid for the duration of your stay, though many airlines recommend having at least six months of validity remaining to avoid any boarding complications. In addition to a passport, as of 2026, all travelers must complete a digital "e-ticket" form (combining immigration, customs, and health declarations) both before entering and before leaving the country. While you do not need a separate paper visa for a standard tourist stay of up to 30 days, you are essentially granted a "tourist card" entry upon arrival, the cost of which is now almost always bundled into the price of your airline ticket to streamline the process at the airport.
