The Cambodia e-Arrival Card (CeA) must be filed within the seven calendar days before your flight lands at Phnom Penh Techo (KTI), Siem Reap Angkor (SAI), or Sihanoukville (KOS) airports. The official portal blocks submissions more than seven days out, though travelers can pre-submit early with Nomadic Mart for automatic queuing.
How the 7-Day Cambodia e-Arrival Card (CeA) Window Is Calculated
Operated by Cambodia’s General Department of Immigration (GDI) at arrival.gov.kh and via the official Cambodia e-Arrival mobile app, the Cambodia e-Arrival Card (CeA) consolidates three legacy paper documents — the Immigration Disembarkation Form, the Health Declaration, and the Customs Declaration — into a single digital QR code. Unlike a Cambodia eVisa, which can be obtained weeks before your trip and remains valid for 90 days from issue, the CeA is strictly tied to your specific inbound flight and arrival date.
Under official GDI rules, the calendar selector for your arrival date only unlocks within seven days prior to your arrival in the Kingdom of Cambodia (Cambodia Time, ICT / UTC+7). For example, if your flight lands at Techo International Airport (KTI) or Siem Reap Angkor International Airport (SAI) on 20 November, the earliest date you can submit directly on the government portal is 13 November.
Why does the government block submissions earlier than seven days? Because airlines, gate assignments, and traveler health histories within the preceding 14 days can change. By restricting direct portal entry to the final seven days before landing, Cambodian immigration ensures that the flight manifest, local lodging address, and customs declaration match your actual trip.
- 15+ days before arrival: Apply for your Cambodia eVisa (Type T or Type E) first; too early for direct CeA portal submission, or pre-queue your CeA order with Nomadic Mart.
- 7 days before arrival: The official CeA 7-day filing window opens (ICT / UTC+7).
- 48 to 24 hours before arrival: Recommended completion target so your QR code is saved before airline online check-in.
- Up until immigration inspection: You may still edit and resubmit your CeA if your flight number or seat changes.
Cambodia CeA (7 Days) vs. Other Southeast Asia Arrival Cards (72 Hours)
If you are traveling on a multi-country Southeast Asia loop in 2026 — such as flying into Bangkok, continuing to Siem Reap and Phnom Penh, and flying onward to Kuala Lumpur or Singapore — keeping track of each country’s digital arrival card countdown is essential. Cambodia is the only country in the corridor that gives travelers a full seven-day submission window.
By comparison, Thailand’s Digital Arrival Card (TDAC, which replaced the paper TM6 in May 2025), Malaysia’s Digital Arrival Card (MDAC), Singapore’s SG Arrival Card (SGAC), Indonesia’s Electronic Customs Declaration and SatuSehat Health Pass, and the Philippines’ eTravel pass all restrict filing to 72 hours (3 days) before arrival. That means on a 5-day stopover in Bangkok before flying to Siem Reap (SAI), you can actually complete your Cambodia e-Arrival Card before you even leave home for Bangkok!
Planning a Bangkok + Siem Reap trip? Because Cambodia offers a 7-day CeA window while Thailand uses a 72-hour TDAC window, you can complete your Cambodia CeA up to a week before your SAI flight.
How Early Queuing Works If You Want Everything Done Weeks in Advance
Many long-haul travelers flying from the United States, the United Kingdom, Europe, or Australia prefer to finish all travel paperwork two or three weeks before departure rather than logging into government portals mid-trip on hotel Wi-Fi. While the official arrival.gov.kh calendar grays out dates beyond seven days, Nomadic Mart’s Cambodia e-Arrival concierge service (starting from $20, all fees included) allows you to submit your passport scan, selfie photo, and flight details as early as you like.
When you submit early through our guided form, our compliance team verifies your passport bio-data scan, checks that your Phnom Penh airport code is set to KTI (not legacy PNH) or SAI for Siem Reap, formats your portrait photo, and holds your file in our automated queue. The moment your 7-day window opens in Cambodia time, we file your declaration and deliver the ready-to-scan CeA QR code PDF directly to your email inbox.
Exact Information Required Inside the 7-Day Window
Whether you file directly on arrival.gov.kh during the 7-day window or use our assisted filing service, the Cambodia e-Arrival system requires specific passport, travel, health, and customs answers for each traveler. Unlike Indonesia’s family customs form, every passenger flying into Cambodia needs their own individual CeA QR code.
- Passport Bio-Data Scan & Portrait Photo: A clear image of your passport photo page (valid for more than 6 months) and a recent portrait photo or live selfie.
- Port of Entry & Flight Details: Select Techo International Airport (KTI), Siem Reap Angkor International Airport (SAI), or Sihanoukville International Airport (KOS), plus your inbound flight number and embarkation city.
- Purpose of Travel & Visa Mode: Indicate whether you hold an approved eVisa, embassy sticker visa, visa exemption, or plan to request a Visa on Arrival.
- Address in Cambodia: Select the province, district, commune, and hotel or residence name where you will stay.
- Health & Customs Declarations: List countries visited in the last 14 days and declare any foreign currency over US$10,000 or goods above duty-free limits.
How to Edit Your CeA If Your Flight Is Delayed or Re-Routed
Flight schedules across Southeast Asia occasionally shift, or an airline may rebook you from an evening flight to the following morning. Fortunately, Cambodia’s General Department of Immigration allows travelers to modify and resubmit their e-Arrival Card at any point prior to physical clearance by an immigration officer at KTI, SAI, or KOS.
Once you resubmit with your updated flight number or arrival date, download or screenshot the newly generated QR code immediately and discard the older screenshot so you present the current version at airline check-in and immigration.
Frequently Asked Questions
Can I submit the Cambodia e-Arrival Card 10 or 14 days before my flight? — Not directly on the government portal, which only unlocks 7 calendar days before arrival. However, you can pre-submit anytime with Nomadic Mart (from $20) and we automatically file your CeA as soon as your 7-day window opens.
What happens if I arrive at KTI or SAI without filing the CeA in the 7-day window? — First, some airlines may refuse boarding at check-in until you show the CeA QR code. Second, if you land without one, you must queue at the arrival hall tablets to complete it before joining the immigration line.
Does the 7-day Cambodia e-Arrival Card window apply to visa-exempt ASEAN citizens? — Yes. All passengers flying into Cambodia — including visa-exempt ASEAN nationals and approved Cambodia eVisa holders — must file the e-Arrival Card within 7 days before arrival.
Is the Cambodia e-Arrival Card valid for multiple entries? — No. Each Cambodia e-Arrival Card (CeA) QR code is valid for a single air arrival. If you leave Cambodia and fly back in later on your trip, you must submit a new CeA within 7 days of your second arrival.
Can I save my Cambodia e-Arrival QR code on my phone or must I print it? — Both are accepted. Official guidance recommends taking a screenshot or downloading the QR code PDF so it works offline without airport Wi-Fi, or carrying a printed paper copy.
How much does the Cambodia e-Arrival Card cost? — Filing directly on the official arrival.gov.kh website or mobile app is completely free ($0 government fee). Optional concierge review and early queuing with Nomadic Mart starts at $20.
