Every traveller flying into Cambodia needs their own e-Arrival Card, and that includes children. Here is how families and groups can get every card filed correctly, in one sitting, without mixing up whose passport goes where.

Yes. Every traveller flying into Cambodia files their own e-Arrival Card under their own passport, and that includes children. There is no single family card, so a family of four files four cards, each with its own QR code. A parent completes the child’s card using the child’s passport details.
Families flying into Cambodia often assume that a parent’s e-Arrival Card covers the children, the way a single booking reference covers the whole family on a flight. It does not. The Cambodia e-Arrival Card is tied to a passport, not to a booking, and every traveller who presents a passport at the immigration desk needs a card that matches it.
That makes the rule for families easy to remember: count the passports. However many passports your family is travelling on, that is how many e-Arrival Cards you need. Two adults and two children means four cards. A grandparent joining the trip means five.
Babies travel on their own passports, so they need their own card too. Cambodia does not publish a separate rule for infants, and we file a card for every traveller in a party, babies included, because each one is presented to Immigration on their own passport.
The child’s. A parent fills in the form, but every identity field comes from the child’s own passport: their full name exactly as printed, their passport number, their date of birth and their nationality. The travel details (flight, arrival date, departure date, next destination and accommodation) will usually match the parent’s, because you are travelling together.
The most common family mistake is a copy-and-paste error: filing a child’s card with a parent’s passport number, or with the older sibling’s date of birth. When you file several cards in a row, the fields that change from card to card are exactly the ones that are easy to leave behind.
Collect each traveller’s passport before you start, so you are copying from the document, not from memory.
Cards can only be filed within 7 days of your arrival date. Aim for 2 to 4 days before you fly.
Work through the family in a fixed order, oldest to youngest, so nobody is missed or done twice.
Before submitting each one, compare the name, passport number and date of birth with the passport in front of you.
Save each QR code with the traveller’s name, and keep a printed set in the passport wallet.
You can start your e-Arrival application for the whole family with us: one order covers every traveller, priced per person, and each card is checked against that person’s passport before it is filed.
Arriving with children is where preparation pays off. After a long flight, with tired children and hand luggage, you do not want to be scrolling through a phone looking for the right QR code. A few habits make the immigration desk quick.
For the ins and outs of saving and showing your codes, see our guide to the e-Arrival Card QR code, and for what happens at each airport, our guide to where the e-Arrival Card is checked.
The same rule applies to any group: one card per traveller. The practical difference with friends or colleagues is that you do not usually hold everyone’s passport. Either each person files their own card, or one person collects a photo of each passport page and the travel details from everyone and files for the group.
If one person files for everyone, ask each traveller to send a clear photo of their passport’s photo page, and confirm their departure date and next destination, since friends often split up at the end of a trip. Do not assume everyone’s onward plans match yours.
When you apply for the e-Arrival Card for a group through us, each traveller’s card is checked against their own passport, and every QR code is emailed to you once filed. Prices are per traveller: $20 Standard, $35 Rush or $60 Super Rush.
If your family’s nationality needs a visa for Cambodia, each child needs their own visa too, in the same way each child needs their own e-Arrival Card. Visas are not shared between parents and children. As with the arrival card, the child’s visa must match the child’s passport exactly.
Check whether your family needs visas with the eligibility checker, and if they do, you can apply for the Cambodia eVisa online for every traveller. Sort the visas weeks before the e-Arrival window opens.

Whether you need a Cambodia e-Arrival Card (and a Cambodia eVisa) during a layover at Techo International Airport (KTI) or Siem Reap (SAI) depends on one question: will you cross the immigration line? Here is the exact 2026 rulebook for airside transfers, separate tickets, and domestic hops.
