Cambodia e-Arrival QR Code Scan at KTI: What US Travelers Do at Immigration

Where the e-Arrival scan happens at Techo International (KTI)

Techo International (KTI) opened in September 2025 and replaced the old Phnom Penh airport, so if a friend tells you about a process they remember from a 2023 trip, set it aside — the building, the counters, and the flow are all new. At KTI the arrivals path is straightforward: you come off the jet bridge, follow the signage down to the Immigration hall, and join the queue for the counters. That is where the e-Arrival QR code comes into play.

There is no separate e-Arrival machine you scan yourself before you reach a human. The QR code is read at the Immigration counter, by the officer, as part of processing your entry. You hand over your US passport, you show the e-Arrival QR code, the officer scans it to pull your declaration, and the two are checked together. Think of it as one combined step rather than a kiosk-then-counter sequence — the card you filed online is the digital version of the paper arrival slip, and the officer is simply opening it.

One thing worth knowing before you land: essentially every American reaches Cambodia by air now, because all seven Thailand-Cambodia land borders have been closed since June 2025. So KTI, Siem Reap-Angkor (SAI), or Sihanouk (KOS) is where your e-Arrival code gets used, and the flow is the same at each. If you want the airport-specific detail on which port your eVisa and e-Arrival are tied to, our guide to the Cambodia e-Arrival port of entry at KTI maps it out.

The two codes you need to keep straight: e-Arrival vs eVisa

Here is the thing that trips up Americans more than the scan itself: you arrive at KTI with two separate documents, and both can look like a QR code or a PDF on your phone. They are not interchangeable, and the officer wants both. Knowing which is which before you reach the desk is what keeps the exchange smooth.

The first is your eVisa — the approval you applied for weeks ahead, delivered as a printable PDF by email after it was approved in 3 business days. That document is your permission to enter Cambodia at all. The second is the e-Arrival Card confirmation, with its QR code, which you filed within the 7 days before your flight. That is your arrival declaration — who you are, your flight, where you are staying, and a short customs answer. The eVisa says you may enter; the e-Arrival Card says here is the detail of this specific arrival. The officer at KTI looks at both.

Set both up so you can produce either in two seconds. Print the eVisa PDF and screenshot the e-Arrival QR code, and keep the printed copies together in your passport. If you are presenting from your phone, have both files open or bookmarked before you join the queue — not buried in an email you have to search for under airport lighting. Our rundown of exactly what to show Cambodia Immigration on arrival lists everything the officer can ask for, in order.

The exchange at the counter, step by step

When you reach the front of the Immigration line at KTI, the whole thing is short and routine. Here is the sequence, so you know what is coming and do not freeze at the desk reaching for the wrong thing.

• You step up and hand the officer your US passport, open to the bio page. That is the anchor — everything else is matched against it.
• You present the e-Arrival QR code, on your phone screen or printed. The officer scans it, and your arrival declaration opens on their side.
• The officer glances between your passport, the declaration, and your face. They are confirming the name and details match and that you are the person on the card.
• They may ask one or two routine questions — how long you are staying, where you are headed, sometimes nothing at all. Answer plainly; this is not an interview.
• They stamp your passport, hand it back, and you walk on to baggage claim. The e-Arrival step is done.

The brightness of your phone screen matters more than you would expect. Turn it up before you hand the phone over, because a dim screen under the counter lighting makes the QR code harder to scan and adds a few awkward seconds while the officer tilts the phone to catch it. A printed copy sidesteps the problem entirely — paper scans the same whether your battery is at 80 percent or dead.

Do not overthink the questions. US tourists and business travelers get waved through with a sentence or two, and the officer has seen a thousand Americans that week alone. Keep your answers short and consistent with what is on your card — if your card says you are staying in Phnom Penh for ten days, do not say "a month, maybe Siem Reap" when asked. The card and your answers lining up is what keeps it to seconds.

When the scan does not go cleanly — and how to avoid it

The scan itself almost never fails on the technical side — a QR code is a QR code, and the counter reader is built for exactly this. What sends Americans to a side desk is a mismatch in the data the scan pulls up. The two that come up most are a name that does not match the passport and an arrival date entered in the wrong format.

The name issue is simple to picture: the e-Arrival Card has to read the same name, in the same order, as the passport you hand over and the eVisa you applied with. If you filed the card as "Jon Smith" but your passport reads "Jonathan Michael Smith," the officer sees a gap and has to resolve it before stamping you. The arrival-date issue is the classic US date-format slip — the form reads day-month-year in places, so a date typed month-first lands you a month off from what the airline manifest says, and that mismatch is the most common reason a US-filed card gets queried at the counter.

If something is flagged, you are not stuck — you are usually directed to a nearby assistance desk to sort it, which costs you time, not your trip. But the entire point of getting the card right before you fly is to never reach that desk. A clean card scans, matches, and stamps in seconds; a card with a name gap or a flipped date turns a smooth arrival into a 20-minute detour at the end of a 20-hour journey from the States.

The other avoidable failure is not having the code at all — a phone that died on the long-haul, or a confirmation you assumed you could re-open on KTI Wi-Fi that you cannot reach past Immigration. The fix is offline copies: a screenshot in your camera roll and a printout in your passport. Our full Techo International arrival walkthrough covers the gate-to-taxi flow, including the SIM and Wi-Fi situation, so you are not relying on a connection you do not have yet.

Getting it right before you fly — so the KTI scan is a non-event

Run a 30-second check before you leave for the airport. The e-Arrival QR code is saved offline, both as a screenshot and a printout. The eVisa PDF is printed and tucked in your passport too. The name on the card matches your passport exactly, middle name included. The arrival date reads correctly in day-month-year and matches your ticket. Four checks, and the scan at KTI becomes the non-event it is supposed to be.

Remember the order of operations for the whole trip: the eVisa is the big step you do first, weeks ahead — Tourist $80 USD or Business $90 USD, both approved in 3 business days and delivered as a printable PDF by email. The e-Arrival Card is the light step you do last, in the week before you fly, and the QR code it produces is what the KTI officer scans. If you want the full picture of the Cambodia visa for US citizens, our pillar guide covers requirements, costs, and timing in one place.

When you file a verified e-Arrival Card through us for $5 USD, it is checked end-to-end before it reaches Cambodian Immigration — the name spelling against your passport, the flight number against your final leg, and the date format that flags so many Americans. That is the difference between a QR code that scans clean at KTI and one that sends you to a side desk. If a field is off, we catch it before it becomes an arrivals problem, with US-timezone support if you have a question the night before you fly.
