You hit submit, then realized your name, date, or flight number is wrong. Here is exactly what US travelers can and cannot edit on a submitted Cambodia e-Arrival Card, the fastest fix for each mistake, and how to avoid the kiosk problem entirely.
There is no reliable self-service "edit" button on a submitted Cambodia e-Arrival Card the way there is on a draft, so the clean fix is to submit a new, corrected card with the right details. The card is tied to your passport and inbound flight, and the officer scans the QR code that matches at the kiosk, so the corrected submission is the one to carry. Focus your effort on the fields that are actually cross-checked — your name exactly as printed on your US passport, your passport number, the final flight leg into Cambodia, and your arrival date. A wrong hotel name or a minor occupation entry rarely needs fixing at all.
You filled in the Cambodia e-Arrival Card, hit submit, and a minute later your stomach dropped: the arrival date is a month off, or your middle name is missing, or you entered your Los Angeles departure flight instead of the final leg into Cambodia. First, breathe. A mistake on a submitted card is one of the most ordinary things that happens with this form, and almost all of it is fixable before you ever reach the kiosk.
The thing to understand up front is that the e-Arrival Card does not work like a passport application you can log back into and amend line by line. It is a short arrival declaration tied to a specific passport and inbound flight, and once you submit it the system treats it as lodged. The practical fix for a real error is not to hunt for an edit screen that may not exist — it is to submit a fresh, corrected card so the QR code the officer scans carries the right information.
This guide sorts the mistakes that genuinely matter from the ones you can safely ignore, walks the fastest fix for each, and shows you how to avoid the whole scramble next time. If you want to see the form laid out cleanly first, our field-by-field e-Arrival Card walkthrough for Americans covers all 14 fields in order. And if you would rather not gamble on a self-fix at all, you can file a verified e-Arrival Card with us and let the correction be our problem instead of yours.
Not every typo is a problem. Before you panic-resubmit, figure out whether the field you got wrong is one Cambodian Immigration actually cross-checks at the kiosk. Some fields are matched against your eVisa and the airline manifest; others are background detail the officer never compares against anything. Fix the first group; leave the second alone.
The high-stakes fields are the ones that have to line up across three places — your e-Arrival Card, your eVisa, and the passport you hand over. Your full name as printed on your US passport, your passport number, your inbound flight number, and your arrival date are what get scanned, compared, and questioned. A mismatch on any of those is the kind of thing that sends a US traveler back to a side desk to sort it out, so those are worth a clean corrected submission.
The low-stakes fields are the ones nobody is matching against a manifest. A hotel name that changed because you rebooked, a city you typed before your plans firmed up, an occupation entry that is close enough — these almost never trigger anything at arrivals. The address on the card is context, not a contract, and Immigration is not calling the hotel to confirm you checked in, so a later change is not worth a fresh submission.
Because there is no dependable self-service edit on a card you have already submitted, the reliable fix for a high-stakes error is to fill out a new card with the corrected details and submit it. This is lighter than it sounds — the card is only 14 fields and you already have everything in front of you. The new card generates its own confirmation and QR code, and that is the one you carry to the kiosk. Set the old screenshot aside so you do not present it by reflex, and keep a single clean copy of the corrected card on your phone, ideally with a printout.
The card must be filed within the 7 days before you arrive, so make sure that window is open before you start the corrected submission.
Fill out all 14 fields again with the corrected details — there is no reliable edit button on a card you already submitted.
Match your name and passport number to your US passport bio page, and enter the final flight leg into Cambodia and the correct arrival date.
The corrected card generates its own confirmation and QR code — that new one is what the officer scans at the kiosk.
Delete or set aside the wrong card so you do not present it by reflex, and keep one clean copy of the corrected card on your phone plus a printout.
Timing is on your side. The card has to be filed inside the 7 days before you arrive, and as long as you are still in that window you can lodge a fresh corrected card without any trouble. The only real pressure is if you submitted very early and the window has not opened yet — in which case wait until you are inside the 7 days, then file the correct card once.
Do not keep firing off duplicate cards "just in case." Once you have submitted a corrected version with the right name, flight, and arrival date, stop there — a stack of near-identical submissions only makes it more likely you scan the wrong QR code at the kiosk. One clean, correct card beats five anxious ones.
Four errors account for almost every flagged US-filed card. Here is what each one looks like and how to make it right, in order of how often we see it.
This is the runaway leader. The form reads day-month-year in places, and Americans default to month-day-year out of habit, so 06/07 typed as "July 6th" gets read as June 7th and your arrival date lands a month off. The fix is mechanical: file a corrected card, and this time use the date picker rather than free-typing the slashes, then sanity-check the result against your flight confirmation. If the screen shows a different day than your ticket, you are still in the trap — adjust before you submit.
The second classic is entering the long-haul flight out of the United States instead of the final leg that actually lands in Cambodia. If you fly Los Angeles to Seoul to Phnom Penh, the flight number on the card is the Seoul-to-Phnom-Penh hop, not the LAX-to-Seoul one. Pull your booking, find the leg whose destination is your Cambodian airport, and resubmit with that flight number — this is the field Immigration cross-checks against the manifest.
A dropped middle name, a nickname instead of the legal first name, or a married name that is not on the passport yet — any of these creates a mismatch between the card, your eVisa, and the document you hand over. Resubmit with your name exactly as printed on your US passport bio page, character for character, including the middle name if it is there. If the same mismatch crept into your visa too, our guide to e-Arrival and US passport name mismatches walks through getting both to agree.
A single swapped or mistyped character in the passport number is easy to do and easy to miss. Open your passport to the bio page, read the number digit by digit, and resubmit. This one is quick to verify and quick to fix, but because the number is matched against your eVisa and the passport itself, it is firmly in the fix-it column.
Say you do not notice the mistake until you are already at the gate, or worse, standing at the arrivals kiosk in Cambodia. It is not a disaster, but it is the version of this problem you most want to avoid, because you are now solving it under time pressure with airport Wi-Fi.
If you spot it before you board, the move is the same as at home: submit a corrected card from your phone while you still have a solid connection, save the new QR code offline, and carry that one — do it in the lounge, not while the agent is scanning boarding passes. If you only realize at the kiosk in Cambodia, stay calm and tell the officer. The e-Arrival Card is an arrival declaration, and a single wrong field is routine for the desk to handle: the realistic outcome is a short delay, not a denied entry, especially when your eVisa and passport are in order.
If your mistake also touched the visa itself rather than just the arrival card, our guide to fixing wrong information on a Cambodia eVisa for US citizens covers that side of the correction.
Run a 30-second review before you ever hit submit, and you skip this whole article next time. Name matches the passport exactly, middle name included. 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. Those four checks catch every mistake that actually matters at the kiosk.
Keep the order of operations straight too. 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, inside the 7 days before you fly. The Cambodia visa for US citizens pillar covers requirements, costs, and timing in one place, and our step-by-step e-Arrival walkthrough shows you the form before you fill it. And if you would rather not do any of this from memory at 2 a.m. before a long-haul flight, you can file a verified e-Arrival Card through us for $5 USD instead.
Next steps and related reading for US travelers: file your verified e-Arrival Card when your flight is locked in, walk the full e-Arrival form field by field if you want to see it first, check your e-Arrival Card status to confirm the corrected version went through, and apply for your Cambodia eVisa if you still need the visa itself.
