What Information You Need for the Cambodia e-Arrival Card (14 Fields, Step by Step)

Section 1 — the five identity fields (all from your passport)

The first section is who you are, and every field is a straight copy off your US passport bio page. The watchword for all five is "exactly as printed." This is the section that has to match your eVisa, and matching is what gets you through the kiosk in seconds instead of minutes.

Full name: enter it exactly as it appears on your passport, including any middle name printed there. If your passport reads "Jonathan" and you go by "Jon," enter "Jonathan." Do not drop a middle name, abbreviate, or reorder the name parts. Passport number: copy it digit by digit and check it twice — a single transposed character is the most common identity-field error we see. Nationality: United States. Date of birth: read the format warning later in this guide before you type it, because the same trap that catches the arrival date catches the birth date. Sex: as shown on your passport.

These five fields are also the ones that have to line up with your visa, so the cleanest approach is to fill the card from the same passport you used to apply. If you have not lined up your visa documents yet, our checklist of the Cambodia eVisa documents required for Americans covers the passport and photo side, and the e-Arrival identity fields draw on the exact same passport bio page.

Section 2 — the four flight-and-stay fields

The second section is how you are arriving and where you are headed. This is the part Cambodian Immigration cross-checks against the airline manifest, so it has to be right — and it is where the two classic American slips live.

Inbound flight number: 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 number on the card is the Seoul-to-Phnom-Penh leg, not the LAX-to-Seoul one. Americans almost always connect through Bangkok, Singapore, Seoul, Tokyo, or Doha, so the flight that matters is the short final hop into Cambodia. Arrival date: the day you land in Cambodia, in the local layout — read the format warning below before you type it. Port of entry: the airport you land at, picked from a list. Address in Cambodia: a hotel name and city is enough, with no booking reference or confirmation required.

On the port of entry, US travelers reach Cambodia at one of three airports in 2026: Techo International (KTI) near Phnom Penh, Siem Reap-Angkor (SAI), or Sihanouk (KOS). Pick the one your final leg actually lands at. If you booked your trip before September 2025 you may still have the old Phnom Penh airport code in your head — the new Techo International (KTI) replaced it, so your ticket and the card should both point at where you are genuinely arriving.

One thing this section never needs: an overland border crossing. All seven Thailand-Cambodia land borders have been closed since June 2025, so essentially every American reaches Cambodia by air and the port-of-entry field is always an airport. If you are still deciding which airport to route through, our guide to which Cambodia airport or port of entry to use for US citizens maps the options and what each is like on arrival.

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.

Putting it together before you file

Run a 30-second review before you submit. Name matches the passport exactly, including the middle name. Passport number has no transposed digits. Flight number is the final leg into Cambodia, not the US departure. Arrival date reads correctly in day-month-year and matches your ticket. Port of entry is the airport you actually land at. Customs answers are honest. Six checks against three sources, and they catch every mistake that sends US travelers back to the kiosk queue.

Keep the order of operations straight for the whole trip. The full picture of the Cambodia visa for US citizens starts with the eVisa — 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. If you have not started the visa yet, our step-by-step guide to applying for a Cambodia eVisa online walks the application end to end, and the small e-Arrival fee is explained in our breakdown of the Cambodia e-Arrival Card fee for Americans.

When you file a verified e-Arrival Card through us for $5 USD, it 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 if Immigration flags a correction there is no extra charge to fix it.
