Getting the Cambodia e-Arrival Card takes about ten minutes once you have the right documents in front of you. The catch is timing: it only opens 7 days before you land. Here is the whole process, step by step.

Wait until you are within 7 days of arriving, then complete the Cambodia e-Arrival form online with your passport details, flight, departure date, next destination and accommodation. Submit it, save the QR code it returns, and show that code to Immigration when you land. Each traveller, including children, files their own card.
The Cambodia e-Arrival Card is the online arrival form that every traveller flying into Cambodia has to file before landing. It replaced the paper immigration card, health form and customs declaration in 2024, and it is now a normal part of preparing for a Cambodia trip, in the same way that checking in online for your flight is.
The process itself is not complicated. What catches people out is the timing, because the form only opens in the final week before you travel, and the detail, because every answer has to match your passport exactly. This guide takes you through both, in the order you will actually do things.
If you are new to the card and want the background first, start with our explainer on what the Cambodia e-Arrival Card is, then come back here for the practical steps.
Gather these before you open the form. Having everything in front of you is the difference between a ten-minute job and a frustrating half hour of hunting through emails.
Travelling as a group? Collect every traveller’s passport before you begin. Each person needs their own card, and it is much easier to file them one after another in a single sitting than to come back to it later.
Once you have your passport and flight details together, you can start your e-Arrival application with us and we will take it from there.
The form opens 7 days before your arrival date and not before. Inside that window, the best time is once your flights have stopped changing. Airlines re-time and re-number flights, and a card that no longer matches your flight is a card you will have to update. Two to four days before you fly is the sweet spot for most travellers: the window is comfortably open, your plans are fixed, and you are filing calmly at home rather than at a departure gate.

Time zones can also play a part. Your arrival date is a date in Cambodia (UTC+7), so if you try to file at the very first moment you think the window is open from the Americas or Europe, the system may still treat you as too early. Filing a few days inside the window avoids the question entirely.
For a fuller explanation of the window, including what happens if you book your trip months ahead, see our guide on when to apply for the Cambodia e-Arrival Card.
Your submission returns a QR code. That code is your e-Arrival Card as far as the airport is concerned, so save it somewhere you can reach without Wi-Fi. A screenshot in your photo library and a printed copy in your passport wallet is the combination that never fails. If you use the official mobile app, the QR code stays available in the app even when you are offline.
Our guide to the e-Arrival Card QR code covers the best ways to store it and what to do if you lose it.
If you spot a mistake after submitting, you can edit and resubmit the card as long as Immigration has not yet processed you. Our guide to correcting a mistake on your e-Arrival Card explains how.
Most problems with the e-Arrival Card are not about understanding the questions. They are about small mismatches between what you type and what is printed in your passport or on your booking. These are the ones that come up again and again.
Enter your name exactly as it appears in the passport’s machine-readable zone and photo page. That means every given name, not just the one you use day to day, and no nicknames or shortened forms. If your passport shows two surnames, include both. If you have recently married or changed your name, use the name in the passport you are actually travelling on, not the one on your new bank card.
Dates are the single most common slip, especially for travellers used to writing the month before the day. Read each date back slowly: your date of birth, your passport expiry, your arrival date and your departure date. A date that is out by a month is easy to miss on screen and awkward to explain at a desk.
If your journey has a connection, the flight the form wants is the one that lands in Cambodia. A traveller flying London to Bangkok to Phnom Penh enters the Bangkok to Phnom Penh flight, not the London departure. Codeshare numbers can also cause confusion, so use the flight number shown on your booking for that final leg.
The card must match the passport you will hand to the officer. If you have renewed your passport since booking, use the new number. If you hold two nationalities, file on the passport you will enter Cambodia with, and make sure your visa, if you need one, is on that same passport.
We collect the full list, with fixes, in our guide to common Cambodia e-Arrival Card mistakes.
You can complete the card yourself, and plenty of travellers do. The reason travellers use a filing service is not that the form is hard; it is that the consequences of small errors land at the worst possible moment, at an immigration desk after a long flight, and that the 7-day window is easy to miss in the busy last week before a trip.
When you apply for the e-Arrival Card through us, we check every field against your passport before we submit it, and if you book more than a week ahead we hold your details and file the moment the window opens. You receive the QR code by email.
Every speed includes free resubmission if Immigration flags a correction. For a side-by-side look at the cost of each route, see our guide to Cambodia e-Arrival Card cost.
The e-Arrival Card is not a visa. It records your arrival; it does not give you permission to enter. Unless your passport is visa-exempt for Cambodia, you need a visa as well, and the visa is the step to sort out first, weeks before the e-Arrival window opens.
Check whether your nationality needs a visa with our eligibility checker. If it does, you can apply for the Cambodia eVisa online: Tourist $80 USD or Business $90 USD, approved in 3–5 days and delivered by email.
