If you have only ever flown to Puerto Rico or the US Virgin Islands, the question makes total sense: does Aruba work the same way, just show a driver's license at the gate and go? It does not. We live here, and we watch this exact confusion trip up first-time visitors at the airport check-in counter more often than almost anything else on this list. So here is the direct answer up front, then the full checklist so nothing catches you off guard.
Yes. US citizens need a valid US passport book to fly to Aruba. Aruba is a constituent country of the Kingdom of the Netherlands, not a US territory, so it is treated as international travel the same way a trip to France or Mexico is. A driver's license, a REAL ID, or a birth certificate will not get you on the plane.
The short answer, then the full checklist
Here is everything a US traveler actually needs to enter Aruba, in the order it tends to come up.
1. A valid US passport book. Not a passport card, more on that below. Aruba does not enforce a strict six-month-validity rule the way some countries do, but the official guidance is that your passport should be valid for the entire length of your stay, and having at least six months of remaining validity beyond your travel dates is still the standard, sensible buffer most airlines and immigration officers expect to see. If your passport is getting close to its expiration date, renew it before you book.
2. The ED card, completed online, plus the $20 sustainability fee. This is a separate step from your passport and it is mandatory for every arrival. We cover the exact process, timing, and the fee in detail in our ED card guide, including the honest warning about third-party sites that charge extra to fill it out for you. Do this on the official government site only.
3. A confirmed return or onward ticket. Immigration can ask to see proof you are leaving, either flying home or continuing to another country. A one-way ticket with no explanation is a real risk of being turned away at the gate or questioned on arrival, since it looks like an attempt to stay without authorization.
4. Proof you can cover your stay, and proof of where you are staying. Officers have discretion to ask for evidence of sufficient funds and a hotel or rental confirmation (or, if you are staying with family or friends, some proof of that arrangement). This is uncommon for a typical week-long vacation with a booked hotel, but it is a real, official requirement, not a rumor. Keep your confirmation email on your phone.
5. Documents for any minor traveling with you. Two separate requirements here, one on each end of the trip, covered in full below.
That is the whole list. No visa is required for US citizens for a standard tourist stay.

Wait, why does Aruba need a passport when Puerto Rico doesn't?
The honest answer is simply what Aruba is. Puerto Rico and the US Virgin Islands are US territories, so flying there is domestic travel by definition. Aruba is one of four constituent countries in the Kingdom of the Netherlands, alongside the Netherlands itself, Curacao, and Sint Maarten. It has its own government, its own immigration service, and its own border. Flying there is international travel in every sense that matters, which is exactly why the passport rule applies and the domestic-travel comparison does not hold.
The passport card mistake, and why it will not work
This is the single most common version of the confusion. The US passport card is real, it is a valid, government-issued travel document, and a lot of travelers assume that because it says "passport" on it, it covers any trip a passport would. It does not.
The passport card is only valid for land and sea entry at land border crossings and sea ports, primarily Canada, Mexico, some Caribbean destinations, and Bermuda. It is not valid for international air travel of any kind, which includes flying to Aruba. If you show up at check-in with only a passport card, you will not be permitted to board. For a flight to Aruba, you need the full passport book. If you have both, bring the book.

How long can US citizens stay, and do you need a visa?
No visa is required for US, Canadian, or EU citizens visiting Aruba for tourism. On arrival, the standard tourist admission is up to 30 days, though US nationals specifically can be admitted for stays of up to 90 days. If you want to stay longer than what you are granted on arrival, extensions are handled through DIMAS, Aruba's immigration directorate, and the total time you can spend in Aruba as a tourist cannot exceed 180 days in a single calendar year. Extensions generally require proof of travel insurance and proof of sufficient funds. If you are planning a longer stay, our guide to working remotely from Aruba goes deeper into the DIMAS process, the 90-day window, and what a longer trip actually looks like in practice.
For the standard one or two-week vacation almost everyone is booking, none of this extension process applies. You will simply be stamped in for your visit and stamped out when you leave.

Traveling with kids: two separate requirements, not one
This is where families get caught out, because there are genuinely two different sets of rules here, one from Aruba and one from the United States, and they are easy to mix up.
Every minor needs their own passport. There is no exception for infants. A baby flying to Aruba needs their own valid US passport book, the same as an adult.
On the Aruba side: if a child is traveling with only one parent, or without either parent, Aruba has an official Permission to Travel with a Minor procedure through the government (a form completed and stamped through Aruban immigration, not something you improvise at the airport). The government specifically asks that this be sorted at least four days before departure, so this is a plan-ahead item, not a day-of one.
On the US side, separately: US Customs and Border Protection may ask for a notarized parental consent letter and the child's birth certificate when a minor is returning to the United States without both parents present, particularly if the child is traveling with one parent, a grandparent, or another adult. This is a US entry requirement, not an Aruba one, but it catches families off guard because it only comes up on the way home.
The honest caveat on both of these: rules like this can be applied with some discretion by individual officers, and family travel situations vary (divorced parents, blended families, a grandparent traveling solo with grandkids). If your situation is not a standard two-parent trip, it is worth confirming the current paperwork directly with the relevant office well before you fly rather than assuming either way.

What actually happens if something is off
Most travelers who show up with a valid passport, a completed ED card, and a return ticket sail through without a single follow-up question. The proof-of-funds and proof-of-accommodation checks exist and are real, but they are applied at an officer's discretion, and a normal vacation with a booked hotel rarely triggers them. Where people actually get stuck is almost always one of three things: a passport card instead of a book, a one-way ticket with no explanation, or a minor traveling without the right documentation. All three are avoidable with about ten minutes of planning before you leave home.
The honest verdict
Aruba is not a hard place to enter. It is a genuinely easy, welcoming island for US visitors, no visa, no complicated interview, no lines that rival a major international hub. The only real trap is assuming it works like a US territory when it does not. Bring the passport book (not the card), complete your ED card on the official site before you fly, keep a return ticket and your hotel confirmation handy, and sort any minor's paperwork a few days ahead if it applies to your trip. Do that, and the passport question stops being something to worry about and becomes a five-minute checklist item.
Once your documents are sorted, the rest of the planning is the fun part. Our flights and getting to Aruba guide covers routes and what to expect on arrival, our Aruba safety guide answers the other question most first-time visitors ask, and our trip planning hub will help you build out the rest of the itinerary once the paperwork is behind you.
