Paying for the Cambodia e-Arrival Card is the easy part — $5 USD verified through us, one card, your usual US card or digital wallet, billed in dollars. Here is exactly how the payment works, which cards go through, and the timing that keeps it clean at the gate.

The Cambodia e-Arrival Card is $5 USD verified through us — a single flat charge, billed in US dollars, paid online when you file the card within 7 days before you land. You pay with a normal US Visa, Mastercard, or American Express card, or a digital wallet such as Apple Pay or Google Pay, the same way you pay for the eVisa. The fee is per traveler, so a family of four pays four times five dollars, including infants, because each card is tied to one passport. It is a separate transaction from your visa: the Tourist eVisa is $80 USD all-in, the Business eVisa is $90 USD, both approved in 3 business days, and the e-Arrival Card sits on top at $5 USD. There is no rush tier, no late surcharge, and no second charge in Cambodian currency waiting at the airport.
Of everything an American does before flying to Cambodia, paying for the e-Arrival Card is the least complicated step. It is a single $5 USD charge, billed in dollars, paid online with the card you already carry. There is no rush option to weigh up, no tiered pricing to decode, and no currency conversion to do in your head. You fill out the card, you pay five dollars, and you get a printable confirmation back. That is the entire payment story.
The questions Americans actually have about the payment are smaller and more practical: which card will go through, will my bank flag a five-dollar charge to a Cambodian-sounding merchant, is the fee per person or per family, and when exactly do I pay it. Those are the things worth knowing before you sit down to file, and they are what this guide answers — the mechanics of the transaction, not a pricing debate.
The Cambodia e-Arrival Card is $5 USD verified through us. That is one flat figure with nothing layered on top — no booking fee, no card surcharge baked into a higher number, no opt-out add-on. You see five dollars at checkout and five dollars is what lands on your statement, charged in US currency.
What the $5 buys is the card itself, lodged correctly inside the 7-day pre-arrival window and delivered to your inbox as a printable confirmation. The card is short — 14 fields across three sections covering you, your trip, and your customs declaration — but the fields are the kind that are easy to get subtly wrong, and a flagged card is a problem you would otherwise discover standing at the immigration desk in Phnom Penh. The payment covers end-to-end checking before the card reaches Cambodian Immigration, plus US-timezone support if a field gets flagged or your flight changes after you file.

You pay for the e-Arrival Card online with the same kind of payment method you would use for any US checkout. A normal Visa, Mastercard, or American Express card — credit or debit — goes through fine, and so do digital wallets like Apple Pay and Google Pay. There is no special arrangement to set up and no Cambodian bank account involved on your side. The charge is processed in US dollars, so your bank sees a clean dollar amount rather than a converted local-currency figure.

Erste Reise nach Kambodscha? Hier ist die ehrliche Checkliste für Erstbesucher aus Amerika — das Visum, die US-Dollar-Geldbesonderheit, die Sicherheitsrealität, die Impfungen, der Tempel-Kleidungsstil und wie die Ankunft am neuen Flughafen im Jahr 2026 tatsächlich aussieht.
Alle sieben Landgrenzen zwischen Thailand und Kambodscha sind seit Juni 2025 geschlossen, daher ist in 2026 der einzige Weg für Amerikaner, von Thailand nach Kambodscha zu gelangen, das Flugzeug. Hier erfahren Sie, wie die Routen Bangkok-nach-Siem Reap und Bangkok-nach-Phnom Penh funktionieren, welches Kambodscha eVisa Sie vor dem Boarding benötigen, und warum der alte Poipet-Überlandplan nicht mehr existiert.
Drei Möglichkeiten, die 310 Kilometer zwischen der Hauptstadt Kambodschas und Angkor Wat zurückzulegen: ein $15 Expressbus, ein 45-minütiger Flug oder eine langsame Flussfähre. Hier erfahren Sie, was jede Option für einen amerikanischen Reisenden tatsächlich kostet, wie lange sie dauert und welche zu Ihrer Reise passt.
For most Americans the payment simply works on the first try. The handful of things that occasionally trip a card up are the same ones that affect any small international online charge: a debit card that is not enabled for online or international purchases, a low-limit card that the bank watches closely, or a fraud filter that pauses an unfamiliar merchant. None of those are about Cambodia specifically — they are your bank being cautious about a transaction it has not seen before.
Tell your bank before you file
A five-dollar charge to an unfamiliar travel merchant is exactly the kind of transaction a US fraud filter pauses. A thirty-second heads-up to your bank — or simply having a backup card ready — clears the most common reason an e-Arrival payment stalls.

The e-Arrival fee is charged per traveler, not per family or per booking. Each person flying into Cambodia files their own card and pays their own $5 USD, including children and infants. There is no family card, no group rate, and no way to cover everyone with a single payment. A family of four flying in together files four cards and pays four times five dollars.
The reason is the same one that applies to the visa: each card is tied to a single passport. The e-Arrival Card carries one person’s passport number, name, and travel details, and it is matched to that passport at the immigration desk. A baby has a passport, so a baby has a card and a $5 fee, even though the parents do the typing. The good news is that you can fill out and pay for several family members in one sitting from the same device — you are filing multiple cards back to back, not wrestling with separate accounts.

You pay for the e-Arrival Card at the same moment you file it, and you file it within 7 days before your arrival in Cambodia. That timing is the one part of the payment worth getting right. Too early — say, the day your visa is approved weeks out — and the card falls outside the window and may need redoing. Too late, and you are paying on airport Wi-Fi with a queue building behind you. The practical sweet spot is two to three days before you fly, once your flight details are settled.
This catches Americans out because the instinct, after the relief of an approved visa, is to clear every remaining form and payment immediately. With the e-Arrival Card that instinct works against you. The card is keyed to a specific arrival date and flight, the system expects that information to be current, and the $5 payment is locked to that filing. File and pay nine days out and you may have to do both again; file and pay inside the 7-day window and it locks in cleanly.

A few of the same wrong assumptions come up again and again about the e-Arrival payment, and clearing them now saves you a surprise later. Most trace back to travelers expecting the card to behave like other entry forms or fees they have run into elsewhere.
