When do I have all the information I need to file?

You have your passport details from the day you apply, and the flight number and arrival date once your booking is locked. The card can only be filed within the 7 days before you arrive, so the natural moment to sit down with all three sources is when you check in online or the day before you leave — your passport, your final-leg flight confirmation, and the name of where you are staying.

What information do US citizens need for the Cambodia e-Arrival Card?

You need 14 pieces of information across three sections. Section one is your identity, copied off your US passport: full name exactly as printed, passport number, nationality, date of birth, and sex. Section two is your trip: the inbound flight number for the final leg into Cambodia, your arrival date, your port of entry, and an address in Cambodia — a hotel name and city is enough. Section three is a short customs and health declaration of yes/no questions, which for most US tourists and business travelers are all "no." There is nothing to upload; you type it all in. Gather your passport, your final-leg flight confirmation, and the name of where you are staying, and you have everything the form asks for.

Key Takeaways

The Cambodia e-Arrival Card collects 14 pieces of information across three sections: who you are, how you are arriving and where you are staying, and a short customs declaration.
Everything comes from three sources you already have: your US passport bio page, your flight confirmation for the final leg into Cambodia, and the name and city of where you are staying.
There is nothing to upload — you type the passport details in by hand, so the data has to match your passport and your eVisa character for character.
The flight field wants the final leg that lands in Cambodia, not your US departure flight, and the date fields read day-month-year, which is the slip that flags most American travelers.
We file a verified e-Arrival Card for $5 USD, checked end-to-end before it reaches Cambodian Immigration, so a typo in your passport number or a backward date does not bounce you at the kiosk.

The short answer: three sources cover all 14 fields

The Cambodia e-Arrival Card looks like a form you should dread and turns out to be one you can finish in a few minutes — once you know what it is actually asking for. There are 14 fields across three sections, nothing to upload, and every single answer comes from one of three places you already have in hand: your US passport, your flight confirmation, and the name of where you are staying. Get those three in front of you and the form has nothing left to surprise you with.

This is the digital version of the little paper arrival-and-customs slip a flight attendant used to hand you on the descent into Phnom Penh. Cambodia moved the whole thing online, so instead of scribbling on a tray table you enter the same information on your phone in the week before you fly and land with a QR code ready to scan. The information is identical to the old paper card; only the timing and the format have changed.

This guide goes field by field so you know exactly what each one wants before you open the form. If you would rather see the screens in the order the form presents them, our walkthrough of how US citizens fill out the Cambodia e-Arrival Card does that. And if you are still working out whether you even need the card, the explainer on whether you need a Cambodia e-Arrival Card settles that first.

Gather these three things before you open the form

The card goes fastest when you never have to stop mid-form to dig for a number. Lay out three things first and you will fill all 14 fields in one sitting without a single guess. None of them takes more than a minute to find.

Your US passport, open to the bio page. Your full name, passport number, nationality, date of birth, and sex all come straight off it, copied character for character — five of the 14 fields, sourced from one page.
Your flight confirmation for the final leg into Cambodia. You need the flight number and arrival date that match the airline manifest, which is the short final hop into Cambodia, not your long-haul departure out of the United States.
The name and city of where you are staying. A hotel, a guesthouse, or a friend's address — a name and city is enough. You do not need a booking reference, a confirmation PDF, or nights-paid evidence.

That is the whole prep list. The customs section in part three asks about what you are physically carrying, so there is nothing to gather for it — you answer from what is in your bags. One timing note: you can only file inside the 7 days before you arrive, so the natural moment to pull these three things together is when your flight details are locked, usually when you check in online or the day before you leave.

Frequently asked questions

What information does the Cambodia e-Arrival Card ask for?

Fourteen pieces of information across three sections. Section one is your identity: full name as printed on your US passport, passport number, nationality, date of birth, and sex. Section two is your trip: inbound flight number for the final leg into Cambodia, arrival date, port of entry, and an address in Cambodia. Section three is a short customs and health declaration of yes/no questions. There is nothing to upload — you type the passport details in by hand.

Do I need to upload any documents for the e-Arrival Card?

No. The e-Arrival Card has no document upload. You type in the details you read off your US passport bio page and your flight confirmation. That is also why accuracy matters so much — there is no scan for the system to fall back on, so a transposed passport-number digit or a backward date is the typed value the kiosk will check against, with nothing to correct it.

Which flight number do I enter on the e-Arrival Card?

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.

What address do I put for where I am staying in Cambodia?

A hotel name and city is enough. You do not need a booking reference, a confirmation PDF, or nights-paid evidence. A guesthouse name, a friend's address, or the first hotel of your trip all work. If your plans shift after you file, the address field is not what Immigration cross-checks — the flight number and arrival date are.

Why does the date format trip up so many US travelers?

The form reads day-month-year in places, while US travelers default to month-day-year. Entering 06/07 expecting July 6th when the system reads June 7th puts your arrival date a month off — the single most common reason a US-filed card gets flagged at the kiosk. Read the field label, use the date picker where you can, and sanity-check the result against your flight confirmation before you submit. The same layout applies to your date of birth.

Does the information on the card have to match my eVisa?

Yes. Your name, passport number, nationality, and date of birth all have to match the eVisa you applied with, because both are tied to the same passport. The cleanest way to guarantee that is to fill the card from the same passport you used for the visa, copying each field character for character. A mismatch between the card and the visa is what slows the kiosk down.

The date format trap, and the five customs questions

Here is the detail that catches more Americans than every other slip combined: the date format. The form reads day-month-year 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 lands a month off. That mismatch against the manifest is the single most common reason a US-filed card gets flagged at the kiosk, and it is a five-second mistake that costs you a trip back to the queue. The same layout applies to your date of birth in Section 1, so the same care applies there.

The fix is mechanical: read the field label and the on-screen format hint before you type, and where you have any doubt, select the day, month, and year from the picker rather than free-typing the slashes. Then sanity-check the result against your flight confirmation — if the screen shows your arrival as a different day than your ticket, you have hit the trap. Fix it before you submit.

The third section is the customs and health declaration — a short set of yes/no questions covering currency over the declarable threshold, restricted or prohibited goods, commercial merchandise, and anything else to declare. For the typical American tourist or business traveler the honest answer to every one of them is no, and that is completely fine. These are the same questions that lived on the old paper card; nothing here is a trick. Answer truthfully, and if you genuinely are carrying something declarable, declare it — the card is not the place to round down.

Once all 14 fields are in and checked, you submit and the system returns a confirmation with a QR code. Save it offline — screenshot it, and ideally print it too — so you are not depending on airport Wi-Fi or a dead battery when you reach the arrivals kiosk. That QR code is what the officer scans to pull your declaration, and it is the only thing you need to have ready at the counter.
