Cambodia e-Arrival Card: How US Citizens Fill It Out Before Arrival

Section 1 — your identity (5 fields)

The first section is who you are, copied straight off your passport bio page. Five fields, and the watchword for every one of them 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 rather than minutes.

Full name: type it exactly as it appears on your US 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, do not abbreviate, do not reorder. The system is matching your name against your eVisa and the passport you will present, and a mismatch is what slows the kiosk down. Passport number: copy it digit by digit and double-check it — a single transposed character is the most common identity-field error. Nationality: United States. Date of birth: covered in the next section's date-format warning, because the same trap applies here. Sex: as shown on your passport.

Section 2 — your flight and stay (4 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 mistakes 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 flight 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, not the long-haul out of the States. Arrival date: the day you land in Cambodia, in the local layout — read the next section 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; no booking reference, no confirmation PDF, no nights-paid evidence.

On the port of entry, Americans 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 before September 2025 you may still see 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 does not need: an overland border crossing. All seven Thailand-Cambodia land borders have been closed since June 2025, so the old Bangkok-to-Siem Reap bus is not an option, and essentially every American reaches Cambodia by air. If you are still deciding which airport to route through, our guide to Cambodia eVisa eligible entry points for US citizens maps which ports accept your eVisa and what each one is like on arrival.

The date format that flags US travelers — and the customs questions

Here is the field that catches more Americans than every other slip combined: the date. 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. 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 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. The same care applies to your date of birth in Section 1 — same layout, same habit, same easy slip. 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 about currency over the declarable threshold, restricted or prohibited goods, and anything to declare. For the typical American tourist or business traveler the honest answer to all of them is no, and that is completely fine. These are the same questions that used to be on the paper card; nothing here is a trick, it simply has to be answered truthfully. Answer honestly, 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.

Getting it right the first time — and where it sits next to your eVisa

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, and they catch every mistake that sends US travelers back to the kiosk queue.

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. If you want the full picture of the Cambodia visa for US citizens, our pillar guide covers requirements, costs, and timing in one place. 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 explainer on whether you need the e-Arrival Card with a Cambodia eVisa confirms that yes, you need both.

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. If the small fee raised an eyebrow, our breakdown of the Cambodia e-Arrival Card fee for Americans explains exactly what the $5 covers and why it sits separate from the visa.

Next steps and related reading for US travelers: file your verified e-Arrival Card when your flight is locked in, confirm whether you need the e-Arrival Card if you have not already, line up the exact information you need for the e-Arrival Card before you sit down, and apply for your Cambodia eVisa if you still need the visa itself.
