For US travelers specifically
No passport. No exchange rate. No customs line.
Puerto Rico is a US territory, which strips out most of the friction of a Caribbean trip. Here is exactly what that means in 2026, including the one ID rule that has actually changed.
The short answer
US citizens and permanent residents need no passport for Puerto Rico. It is domestic travel, same currency, same phones, no border crossing. The one thing that has actually changed for 2026: TSA now fully enforces REAL ID at the gate, so bring a compliant license, a passport, or a Trusted Traveler card, not just an old standard driver's license.
The one rule that changed
What ID you actually need
Not a passport requirement. A domestic ID requirement, and it now applies at every US airport, including San Juan's.
As of 2026, TSA is fully enforcing the REAL ID Act. A standard, non-compliant state driver's license is no longer enough on its own to board a domestic flight, including SJU to the mainland and back. Bring one of: a REAL ID-compliant license or ID card, marked with a star; a US passport or passport card; a DHS Trusted Traveler card such as Global Entry, NEXUS, or SENTRI; or a US military ID. If you show up without a compliant ID, TSA now offers a paid identity-verification process as a fallback, but the simpler move is checking your license for the star before you fly.
No math at checkout
No currency exchange
US dollars, the whole trip.
The US dollar is Puerto Rico's only currency. No exchange counter at the airport, no guessing at a conversion rate on the bill, and no leftover foreign coins at the end of the trip. Cards are widely accepted; carry some cash for kiosks, tips, and smaller local spots.
Your phone just works
US phone plans
One less thing to plan around before you fly.
Most major US carriers treat Puerto Rico as part of standard domestic coverage rather than international roaming, so for most travelers a phone plan that works at home works here too. Confirm your specific plan's coverage before you fly if you are unsure, but the general expectation is straightforward: no international SIM, no roaming charges most visitors need to think about.
The one real checkpoint
No customs, but one bag check
Not customs. An agricultural inspection, and it is genuinely worth knowing about before your flight home.
There is no immigration or customs process flying between the mainland and Puerto Rico. There is, however, a federal USDA agricultural inspection every passenger clears before checking bags for a flight out of San Juan back to the mainland, screening for items like fresh produce, plants, and pork products that could carry pests or disease to the continental US. Each terminal has its own screening point, the process itself is quick, but build in some extra time at the airport for the line rather than cutting it close on a standard domestic-flight schedule.
What you don't need
Global Entry and TSA PreCheck
A trip built for skipping the usual airport friction, not adding to it.
Global Entry exists for re-entering the US after international travel, so it has no role on a trip that never technically leaves the country. TSA PreCheck, if you already have it, works exactly as it does at any other domestic US airport, San Juan included.

Read the guideStraight answers on the logistics
Do I need a passport to go to Puerto Rico?
No, not if you are a US citizen or permanent resident. Puerto Rico is a US territory, so travel there from the mainland is domestic travel, the same as flying to any US state. A standard, valid ID for domestic flying is all you need.
What ID do I actually need to fly to Puerto Rico?
A REAL ID-compliant driver's license or ID card, identifiable by a star marking, a US passport or passport card, a DHS Trusted Traveler card such as Global Entry, or a US military ID. TSA is now fully enforcing REAL ID for domestic boarding, so a standard, non-compliant license alone is no longer accepted at the gate; travelers without a compliant ID can pay a fee for an alternate identity-verification process, but bringing a compliant ID is the simpler move.
Do I need Global Entry or TSA PreCheck for Puerto Rico?
Neither is required. Global Entry is built for re-entering the US after international travel, and a Puerto Rico trip never leaves US jurisdiction, so it does not apply here. If you already have TSA PreCheck, it works normally at San Juan's airport like any other US airport.
Do I go through customs coming back from Puerto Rico?
No immigration or customs check, but there is one real checkpoint: a USDA agricultural inspection before you leave San Juan, screening checked and carry-on bags for items like fresh produce, plants, and pork products that could carry pests into the mainland. It is quick, but budget a little extra time at the airport for it.
