Do I still need the e-Arrival Card if I have an eVisa?

Yes. The e-Arrival Card is not your visa — it is a separate arrival-and-customs declaration that every air arrival files on top of an approved eVisa. No app and no website changes that. The eVisa is the bigger step you handle weeks ahead, approved in 3 business days and delivered as a printable PDF by email; the e-Arrival Card is the light step you file in the 7 days before you fly.

Do children need their own e-Arrival Card on the app?

Yes. Every traveler needs their own e-Arrival Card under their own passport, including infants and children on a US passport, and that holds whether you use the app or the website. There is no family-group shortcut and no shared submission. A baby on your lap still counts as a separate arrival and needs a separate card, filled out with the child's own passport details.

Cambodia e-Arrival App vs Website: Which Should US Travelers Use?

The Cambodia e-Arrival app and the website ask for the same 14 fields and produce the same QR code. Here is which one actually fits how US travelers work, the offline-QR question that matters at the kiosk, and the date-format slip that flags Americans on either one.

Should US travelers use the Cambodia e-Arrival app or the website?

Either one works — the Cambodia e-Arrival mobile app and the website are two interfaces to the same system, asking the same 14 fields, filed in the same 7-day window, and producing the same QR code you scan at the kiosk. Neither is faster or more official than the other. For most Americans the practical answer comes down to device: use the website on a laptop if you want a full keyboard and a big screen to copy your passport and flight details cleanly, or use the app on your phone if you want the finished QR code living on the device you will actually hold at arrivals. What matters is not the tool but the QR code at the end, and getting the name spelling, the final flight leg, and the day-month-year date format right. Save the QR code offline either way, because the arrivals hall is no place to depend on airport Wi-Fi.

主なポイント

The Cambodia e-Arrival app and the website are two front doors to the same 14-field form — same questions, same 7-day window, same QR code at the end. Neither gives you a faster result.
Use the website on a laptop if you like a full keyboard and a big screen for copying passport and flight details; use the app on your phone if you want the QR code living on the device you will actually scan at the kiosk.
The QR code is what matters at arrivals, not which tool made it — screenshot it and print it either way, because the kiosk hall is not where you want to discover airport Wi-Fi is down.
The date format is the single most common US slip on both the app and the website: the form reads day-month-year in places, so 06/07 is June 7th, not July 6th.
We file a verified e-Arrival Card for $5 USD, checked end-to-end before it reaches Cambodian Immigration, so a date-format slip, a name mismatch, or a wrong flight leg does not bounce you back to the queue — whichever tool you would otherwise have used.

App or website? They are the same form, two front doors

Start here, because it saves you a lot of second-guessing: the Cambodia e-Arrival mobile app and the e-Arrival website are not two different processes. They are two front doors to the same system. The same 14 fields, the same three sections, the same 7-day pre-arrival window, and the same QR code at the end. Filing on the app does not get you a faster result than filing on the website, and the website is not more official than the app. They feed the identical declaration to Cambodian Immigration.

So the question is not "which one is correct" — both are. The question is which one fits how you actually work and, more importantly, where you want the finished QR code to live when you step off the plane. That second part is the one travelers underthink, and it is where the real decision sits for US travelers connecting through long layovers with patchy Wi-Fi and a phone battery that has been working hard all day.

This guide lays out the honest trade-offs between the two, the offline-QR question that decides it for a lot of people, and the slips that flag a US-filed card on either tool. If you would rather just see the form filled out start to finish, our step-by-step e-Arrival Card walkthrough for Americans does exactly that. And when you are ready, you can file a verified e-Arrival Card with us in a few minutes, on whichever device you have to hand.

Pick your front door
App or website — both file the same 14-field card across three sections and hand you the same QR code.
Choose by device
Use the website on a laptop for a full keyboard and big screen, or the app on the phone you will scan with at the kiosk.
File inside the 7-day window
Submit the card within the 7 days before you arrive, after your final flight leg into Cambodia is locked in.
Mind the date format
The form reads day-month-year in places, so 06/07 means June 7th, not July 6th — use the picker and check it against your ticket.

よくある質問

Is the Cambodia e-Arrival app different from the website?

No. They are two front doors to the same system — the same 14 fields across three sections, the same 7-day pre-arrival window, and the same QR code at the end. Filing on the app is not faster than the website, and the website is not more official than the app. They feed the identical arrival declaration to Cambodian Immigration. The only meaningful difference is the device you fill it on and where the finished QR code ends up.

Should I use the app or the website to file my e-Arrival Card?

Pick by where you want the QR code to live. Use the website on a laptop if you want a full keyboard and a big screen to copy your passport and flight details cleanly — then move the QR to your phone before you fly. Use the app if you want the finished QR on the device you will actually scan with at the kiosk, or if you are filing on the move during a layover. Either produces the same valid card.

Does the Cambodia e-Arrival QR code work offline?

Filing the card needs a connection, because you are submitting data to a government system. But once the card is submitted and the QR code is generated, that code is saved on your device and displays at the kiosk without live Wi-Fi. That is the offline benefit people ask about — not filing offline, but having the finished QR available offline at arrivals, where airport Wi-Fi is unreliable. Screenshot it and print a paper copy as a backup either way.

Is it safe to download a Cambodia e-Arrival app?

Be deliberate about it. The arrival-card space attracts copycat apps and pages built to collect your passport details and money. Do not tap the first sponsored result and start typing personal data — look at who is behind the page before your passport number, date of birth, or card details go in. The same caution applies to website results. Filing through a verified service avoids the "is this app real" gamble and pairs it with US-timezone support.

Which flight number do I enter, on the app or the website?

The final leg that actually lands in Cambodia, not your US departure flight. If you fly Los Angeles to Seoul to Phnom Penh, you enter the Seoul-to-Phnom-Penh flight number. Americans almost always connect through Bangkok, Singapore, Seoul, Tokyo, or Doha, so the flight that matters is the short final hop into Cambodia — the one Immigration cross-checks against the manifest. This is the same on both tools.

When the mobile app is the better call

The single strongest argument for the Cambodia e-Arrival mobile app is the one the website cannot match without an extra step: the finished QR code lives on the exact device you will be holding when an officer at Techo International asks to scan it. No emailing it to yourself, no transferring a screenshot across devices, no realizing at the kiosk that the QR is on a laptop in checked baggage. You filed it on the phone, and the phone is what you hand over.

The app also wins on timing for the way the card actually works. You can only file inside the 7 days before you arrive, and that window often lands while you are already moving — the day before you fly, or during a layover when your flight details are finally locked. If you are sitting in a terminal in Seoul or Doha between legs, you are not opening a laptop. The phone in your pocket is the only tool you have, and the app is built for exactly that moment.

There is a real offline benefit too, and it is worth being precise about it. Filing the card needs a connection — you are submitting data to a government system, so you cannot complete the form with no signal at all. But once you have submitted and the QR code is generated, that code is saved on your device and does not need live Wi-Fi to display at the kiosk. That is the "offline QR" people ask about: not filing offline, but having the finished QR available offline at arrivals, where airport Wi-Fi is unreliable and your roaming may not have kicked in yet.

One more thing the app makes easy: checking your status before you fly. If you want to confirm the card went through and the QR is valid, you can open it back up on the phone and look. Our guide to checking your e-Arrival status and QR code for Americans covers exactly what a healthy confirmation looks like and what to do if it is not there.

The slips that flag US travelers — on the app and the website both

Because the app and the website are the same form, they share the same mistakes. The interface you pick does not protect you from any of these, so they are worth knowing cold before you type a single field, whichever tool is in front of you.

The date format is the big one. The form uses a day-month-year layout in places, and US travelers default to month-day-year out of pure habit. Enter 06/07 thinking July 6th when the system reads it as June 7th, and your arrival date is suddenly a month off — the single most common reason a US-filed card gets flagged at the kiosk. The fix is mechanical on both tools: read the field label and the on-screen format hint, use the date picker rather than free-typing the slashes, and sanity-check the result against your flight confirmation before you submit.

The flight number is the second classic. Enter the final leg that actually lands in Cambodia, not your US departure flight. If you fly Los Angeles to Seoul to Phnom Penh, the flight on the card is the Seoul-to-Phnom-Penh leg, not the long-haul out of LAX. Americans almost always connect through Bangkok, Singapore, Seoul, Tokyo, or Doha, so the flight that matters is the short final hop — that is the one Immigration cross-checks against the manifest. And on the port of entry, US travelers arrive at one of three airports in 2026: Techo International (KTI) near Phnom Penh, which replaced the old Phnom Penh airport in September 2025, Siem Reap-Angkor (SAI), or Sihanouk (KOS). One reason the overland question never comes up: all seven Thailand-Cambodia land borders have been closed since June 2025, so essentially every American reaches Cambodia by air.

The third is name discipline. Type your name exactly as printed on your US passport, including any middle name, in the same order. The card is matched against your eVisa and the passport you present at the kiosk, and a mismatch slows everything down. None of these three slips care whether you used the app or the website — they care whether you read the field and checked it.

The verdict — and where this sits next to your eVisa

Here is the clean answer. There is no wrong choice between the app and the website — both file the identical 14-field card and both hand you the same QR code. Pick by where you want that QR code to live. If you want it on the phone you will scan with at the kiosk and you are filing on the move, use the app. If you want a full keyboard and a big screen to get every character right and you are filing from your desk, use the website — then move the QR to your phone before you fly. The one rule that holds in every case: screenshot the QR, print it, and never count on airport Wi-Fi.

Remember the order of operations for the whole trip: the eVisa is the big step you do first, weeks ahead — Tourist $80 USD or Business $90 USD, both approved in 3 business days and delivered as a printable PDF by email. The e-Arrival Card is the light step you do last, in the week before you fly, on whichever tool you prefer. If you want the full picture of the Cambodia visa for US citizens, our pillar guide covers requirements, costs, and timing in one place. And if you are traveling with kids, our guide to the e-Arrival Card for children confirms that yes, each child needs their own card, app or website notwithstanding.

When you file a verified e-Arrival Card through us for $5 USD, it does not matter which front door you would otherwise have used — your card is checked end-to-end before it reaches Cambodian Immigration. The name spelling against your passport, the flight number against your final leg, and the date format that flags so many Americans. If a field is off, we catch it before it becomes a kiosk problem, and you deal with US-timezone support if you have a question, not a copycat app of unknown origin.

Next steps and related reading for US travelers: file your verified e-Arrival Card when your flight is locked in, walk the full form field by field if you want to fill it yourself, line up how to check your e-Arrival status and QR code before you fly, and apply for your Cambodia eVisa if you still need the visa itself.
