当您在7天窗口内整齐填写了柬埔寨电子到达卡后,航空公司重新为您预订了航班。有时该卡仍然有效。有时您需要从头重新填写。本指南告诉您哪种情况适用,以及移民官员实际上如何处理过期的二维码。

It depends on what changed. A minor change — different flight number on the same day into the same airport — is accepted at Cambodian Immigration on your existing Card. The officer scans the QR code at the kiosk and waves you through. A major change — different arrival airport, different arrival date, or a rerouted stopover that lands you on a different calendar day — means re-filing the Card from scratch, because the portal does not allow edits on a confirmed submission. Most Aussie schedule changes inside the 7-day pre-arrival window are accepted on the original Card; the cases that need a fresh submission are airport-or-date changes. If you re-file, carry both QR codes through Immigration. Our verified e-Arrival is $5 USD (~$7.50 AUD), delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and Aussie-timezone support if the airline changes your schedule mid-week.
This guide covers the three scenarios — rebooking, delay, cancellation with rerouting — and what to do in each. If you have not yet filled the Card and want the field-by-field walk-through, the Cambodia e-Arrival 14-fields walkthrough is the place to start, and the Cambodia e-Arrival when-to-fill guide covers the timing inside the 7-day window. For the canonical reference on cost, documents, and processing, see the apply for your Cambodia eVisa hub.
Re-filing inside the 7-day window is free on the official portal, or part of the $5 USD (~$7.50 AUD) verified e-Arrival fee through us with free resubmission if Immigration flags a correction. The Cambodia e-Arrival rejection fixes guide covers the in-the-moment workflow at the kiosk if a Card mismatch is queried.

If you used our verified e-Arrival service, the re-file is free and we keep the original submission on record so the Aussie-timezone team can confirm exactly which Card is active by the time you fly. The Cambodia e-Arrival when-to-fill guide covers the broader timing question for first-time filers.


For the airport-specific context, the Cambodia airports KTI, SAI, and KOS guide covers each entry point. If you have already arrived without a working Card and need to know what happens at the manual desk, the Cambodia e-Arrival rejection fixes guide is the right reference.

Reroutes via Bangkok still work as a transit stop.

Check three things: arrival airport, arrival date (in local Cambodia time), and passport number. If all three still match the Card you submitted, you are fine — fly with what you have, present the QR at the kiosk, and the flight-number drift is informational. If the airport changed, the date changed, or both, re-file the Card with the new details before clearing Immigration. The portal does not edit confirmed submissions — every fix is a fresh submission. If you re-file through our verified e-Arrival, it is $5 USD (~$7.50 AUD), delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and Aussie-timezone support if the schedule shifts again. If you have not yet filed at all, the how-to-apply Cambodia eVisa from Australia walkthrough is the broader trip-prep reference and the do-Australians-need-Cambodia-visa pillar covers the policy framing for anyone planning a first trip.
