Cambodia e-Arrival Card for South Korean Travellers: 2026 Filing Rules

Why South Korean travellers need both a visa and the Cambodia e-Arrival Card

Whether you are flying direct from Seoul Incheon (ICN) to Phnom Penh for business or connecting via Vietnam or Bangkok to Siem Reap for an Angkor Wat and golf holiday, air arrival in Cambodia in 2026 requires two separate digital documents: a Cambodian visa and the Cambodia e-Arrival Card (CeA).

Even if you already have your $80 USD Tourist eVisa (Type T), your $90 USD Business eVisa (Type E), or a long-term multiple-entry E-class extension stamped in your Korean passport, you must still complete a new Cambodia e-Arrival Card before every flight into Cambodia. The card replaces the three paper forms that used to be distributed in the cabin and returns a QR code that Immigration scans on arrival.

If you still need to arrange your visa first, read our guide on whether South Korean citizens need a visa for Cambodia in 2026, or visit our Cambodia visa hub for South Korean citizens.

2026 filing rules: the 7-day window, Korean given-name spacing, and onward travel fields

The Cambodia e-Arrival Card opens 7 days before your arrival date in Cambodia. To avoid delays at check-in at Incheon (ICN) or Busan Gimhae (PUS), follow these four rules when entering your details:

New in 2026, the e-Arrival form asks for your departure date from Cambodia and your next destination (whether returning to Incheon or flying on to Vietnam or Thailand). If you file with us and have not booked onward travel yet, our form lets you say “not booked yet” and we email you to add it later.

Worried about what happens if your flight number changes or you spot a typo in your passport number? See our guide to what happens if your Cambodia e-Arrival Card has wrong details.

Direct flights from Incheon vs connections via Vietnam or Bangkok—and the closed Thailand border

Which flight number you enter on your e-Arrival Card depends on whether you fly non-stop or connect through another Southeast Asian city:

• Non-stop from Seoul Incheon (ICN) to Phnom Penh (KTI): Enter your direct flight number (for example Korean Air KE689, Asiana Airlines OZ739, or Sky Angkor Airlines ZA216) and select Techo International Airport (KTI).
