Ja. Wenn Sie nach Kambodscha fliegen, ist die e-Arrival Card obligatorisch — ein separates digitales Formular neben Ihrem eVisa, 14 Felder, einzureichen innerhalb von 7 Tagen vor Ihrer Landung. Hier erfahren Sie genau, wer sie benötigt und was sie nicht ist.

Yes. Every traveler arriving in Cambodia by air must submit the Cambodia e-Arrival Card, and that includes US citizens with no exemptions for tourists, children, or short visits. It is a separate digital form from your eVisa — 14 fields covering your identity, your flight, and a customs declaration — and you file it within the 7 days before you land. The e-Arrival Card does not replace your visa. You need an approved Cambodia eVisa to enter the country and the e-Arrival Card as your arrival declaration. Americans flying into Phnom Penh, Siem Reap, or Sihanoukville all need both.
Yes, you need it. If you are a US citizen flying into Cambodia, the e-Arrival Card is mandatory — there is no version of an air arrival in 2026 that skips it. The confusion is almost never about whether you need it. It is about what it actually is, because the name makes it sound like a visa, and it is not.
Think of the e-Arrival Card as the digital replacement for the little paper arrival-and-customs card a flight attendant used to hand you on the descent into Phnom Penh. Cambodia moved that whole process online. Instead of scribbling your passport number on a tray table at 30,000 feet, you fill in the same information on your phone in the week before you fly. Same questions, better timing, no pen required. The result is that you walk off the plane with your arrival declaration already lodged and a QR code ready to scan.
The rule is simpler than most entry rules: if you arrive in Cambodia by air, you file the e-Arrival Card. Nationality does not change it, age does not change it, and the length of your trip does not change it. American leisure travelers, business travelers, families, retirees, students, and dual citizens entering on a US passport all file the same card.
The most common mistake Americans make is assuming there is an exemption that applies to them. There is not. A toddler on your lap needs their own e-Arrival Card filed under their own passport. A 48-hour layover-turned-stopover where you leave the airport needs one. A second trip three weeks after your first needs a fresh card — it is per arrival, not per traveler per year. If your feet touch Cambodian soil off an inbound flight, you are in scope.

This is the single most important thing to get straight, because filing the e-Arrival Card and skipping the eVisa is how Americans get turned away. They are two different documents that do two different jobs, and Cambodian Immigration checks for both.

Erste Reise nach Kambodscha? Hier ist die ehrliche Checkliste für Erstbesucher aus Amerika — das Visum, die US-Dollar-Geldbesonderheit, die Sicherheitsrealität, die Impfungen, der Tempel-Kleidungsstil und wie die Ankunft am neuen Flughafen im Jahr 2026 tatsächlich aussieht.
Alle sieben Landgrenzen zwischen Thailand und Kambodscha sind seit Juni 2025 geschlossen, daher ist in 2026 der einzige Weg für Amerikaner, von Thailand nach Kambodscha zu gelangen, das Flugzeug. Hier erfahren Sie, wie die Routen Bangkok-nach-Siem Reap und Bangkok-nach-Phnom Penh funktionieren, welches Kambodscha eVisa Sie vor dem Boarding benötigen, und warum der alte Poipet-Überlandplan nicht mehr existiert.
Drei Möglichkeiten, die 310 Kilometer zwischen der Hauptstadt Kambodschas und Angkor Wat zurückzulegen: ein $15 Expressbus, ein 45-minütiger Flug oder eine langsame Flussfähre. Hier erfahren Sie, was jede Option für einen amerikanischen Reisenden tatsächlich kostet, wie lange sie dauert und welche zu Ihrer Reise passt.
A useful way to hold it in your head: the eVisa is the ticket, the e-Arrival Card is the boarding announcement. You cannot board on the announcement alone, and the ticket without checking in does not get you through the gate. You need both, in that order — eVisa approved first, e-Arrival Card filed in the final week before you fly.

The e-Arrival Card is 14 fields, and that is the whole thing. It is short enough that the temptation is to rush it — which is exactly where the avoidable slips happen. The fields break into three sections: who you are, how you are arriving, and what you are bringing in.
Your full name exactly as printed on your US passport, your passport number, your nationality, your date of birth, and your sex. The watchword here is "exactly as printed." If your passport reads your name one way and you type it another — a dropped middle name, a maiden name, a typo in the passport number — the card can fail to match your eVisa, and matching is what gets you through the kiosk quickly.
Your inbound flight number, your date of arrival, the port you are arriving at, and the address where you will stay in Cambodia. A hotel name and city is enough for the address — you do not need a booking reference or a confirmation PDF. The flight number and arrival date have to be right, because this is the part Immigration cross-checks against the manifest. Americans connecting through Bangkok, Singapore, or Seoul should enter the final leg into Cambodia, not their US departure flight.
A short set of yes/no customs and health questions — whether you are carrying currency over the declarable threshold, restricted goods, and so on. For the typical US tourist or business traveler the honest answer to all of them is no, and that is fine. These are the same questions that used to be on the paper card; nothing here is a trap, it just has to be answered truthfully.

The e-Arrival Card has a timing rule that is the mirror image of the eVisa, and getting it backward is the most common scheduling mistake Americans make. You file the e-Arrival Card within the 7 days before you arrive — not months ahead, the way you do the visa. File it too early and the system will not accept it yet.
So the natural rhythm of a US trip looks like this: apply for your eVisa weeks ahead, let it land in your inbox as a PDF, and forget about it. Then, in the week before you fly, file the e-Arrival Card. A good anchor is to do it the same day you check in online for your flight, or the day before you leave — by then your flight details are locked, which means you can enter them correctly the first time.
The reason the window matters is that the card is tied to a specific arrival. Cambodian Immigration wants a current declaration for the flight you are actually on, with the flight number and date that match the manifest. A card filed three months out against a flight you had not booked yet is useless to them. Seven days out, your plans are real, and the data holds.
For Americans, the practical trap is the date. The form uses a day-month-year layout in places, and US travelers default to month-day-year. Enter 06/07 thinking July 6th when the system reads June 7th, and your arrival date is suddenly a month off — which is the single most common reason a US-filed card gets flagged at the kiosk. It is a five-second mistake that costs you a trip back to the queue.

Second, in the week before you fly, file the e-Arrival Card. When you file a verified card through us for $5 USD, it is checked end-to-end before it reaches Cambodian Immigration — name spelling against your passport, flight number against your final leg, and the date format that catches so many Americans out. The single date-format slip that sends travelers back to the queue is exactly the kind of thing that check is built to catch.
