You spotted a wrong date of birth, a misspelled name, or the wrong passport number on your Cambodia eVisa. Here is exactly what US citizens can fix, what triggers a fresh application, and how to catch the error before Immigration does.

It depends on timing. If your application is still processing and has not been approved, the information can usually be corrected — you reply with the right details and the file is updated before it is finalized. Once the eVisa is approved and the PDF is issued, the document is locked and cannot be edited; a material error like a misspelled name, wrong passport number, or wrong date of birth needs a fresh, corrected application instead. The four fields that matter most for entry are your full name, passport number, date of birth, and nationality — those are what Cambodian Immigration matches against your passport at the gate. Apply through us and a flagged correction is reissued at no extra charge as a new printable PDF, usually inside the same 3-business-day window.
You hit submit, the confirmation page loaded, and then you saw it — the date of birth reads 1987 instead of 1978, or your middle name is missing, or the passport number has a transposed digit. The instinct is to assume the whole application is ruined and the money is gone. It almost never is. Most wrong-information situations on a Cambodia eVisa are fixable, and the ones that are not still resolve quickly when you act before you fly.
What matters first is timing. A Cambodia eVisa moves through a short processing window — approved in 3 business days — and where your file sits in that window decides which fix you need. If it is still being processed, the information can usually be corrected in place. If the eVisa has already been approved and the PDF has landed in your inbox, the document is locked and a different path applies. Knowing which stage you are at saves you from doing the wrong thing in a hurry.
This guide walks through exactly what you can fix and when, which errors actually stop US travelers at the airport versus which ones never matter, and how to catch a mistake before Cambodian Immigration does. If you have not started yet, the cleanest fix is avoidance — our step-by-step application walkthrough for Americans shows you each field before you commit it. And if you are ready to lodge a corrected file, you can apply here.
There are two windows. Before approval, your application data is still editable on the back end, so a correction is a matter of getting the right details to us before the file is finalized. After approval, the eVisa is a fixed, issued document — the same way a printed boarding pass cannot be re-typed once it is in your hand. Here is how each window works in practice.
If your eVisa is still processing, reply to the confirmation email you received after submitting and state the field that is wrong and the correct value exactly as it appears in your passport. Do not start a second application — a duplicate file under the same passport is one of the most common self-inflicted delays we see, because it forces a manual untangle before either file can move. One message, the right correction, and the file gets updated before it reaches Cambodian Immigration.
Move fast in this window. The 3-business-day clock is already running, and the sooner the correction lands, the more likely it is folded in without resetting anything. A correction sent within hours of submitting almost always rides the original timeline. A correction sent on day three is tighter.
Once the eVisa PDF is issued, the document cannot be edited. There is no field on an approved Cambodia eVisa you can go back and change — the name, number, dates, and photo are baked into the issued file. A material error at this stage needs a clean, corrected application rather than an edit. The good news for US travelers who applied through us: a corrected re-file is reissued as a fresh printable PDF, and because we treat a flagged correction as part of the all-in price, you are not paying a second full fee to fix our queue. If you are unsure whether your specific error is material, our

The Cambodia e-Arrival Card is a separate step from your eVisa, and a small one — $5 USD verified through us, 14 fields, filed within 7 days before you fly. Here is exactly what that fee covers, why it is not bundled into your visa price, and the timing that keeps you moving at the gate.
The Cambodia e-Arrival Card is 14 fields across three sections, filed within 7 days before you land. Here is exactly what each field wants, in the order the form asks for it, plus the date-format slip that flags US travelers at the kiosk.
The Cambodia e-Arrival Card asks for 14 pieces of information across three sections — your identity, your flight and stay, and a short customs declaration. Here is exactly what each field wants and the four things to have in front of you before you start.
Rule of thumb: if the eVisa is still "processing," treat it as fixable and reply with the correction now. If the approved PDF is already in your inbox, treat it as a replacement, not an edit — and check the four entry-critical fields below before you do anything else.
Not every typo is equal. At the arrivals desk, a Cambodian Immigration officer is matching your eVisa against the passport in their hand, and they are looking at four things. Get these right and a minor mismatch elsewhere is usually a non-event. Get one of these wrong and you risk a hold at the gate or a denied boarding before you even leave the US.
Notice what is not on that list. Your intended address in Cambodia, your arrival date, and your occupation are not gate-matched against a second document the way your passport identity is. An imperfect hotel name or a tentative arrival date is not the emergency a wrong passport number is. We will come back to those low-stakes fields in the next section so you know what you can safely leave alone.
The name field is where US travelers trip most often, usually because of how American passports format names. If your passport shows a hyphenated surname, a suffix like "Jr," or a middle name you normally drop, the eVisa must follow the passport, not your everyday signature. Our deep-dive on name and passport mismatches for US citizens covers the exact formatting rules and the edge cases — hyphens, two surnames, recently married names — that cause the most resubmissions.
Half the panic emails we get are about fields that do not actually affect entry. Before you re-file anything, check whether your "error" is one of these low-stakes ones. If it is, you can often leave it — and save yourself the time and the second upload.
The big exception to the "do not worry" list is visa type. Address and arrival-date slips are forgivable; choosing the wrong visa category is not a cosmetic error and does not self-correct. If you suspect you applied for the wrong type — a Business eVisa for a pure tourist trip, or the reverse — that is a different fix entirely, and our guide to checking and correcting your application status for Americans walks through how to confirm what you actually submitted.
Work through these in order. The first question — has it been approved yet — decides everything, so answer that before you do anything else.
Reply to your confirmation email immediately. Name the field (for example, "passport number"), give the correct value exactly as printed in your passport, and attach a clear scan of your passport bio page so the correct details can be verified against the source. Do not open a second application. A correction supplied while the file is still open is folded in before it reaches Cambodian Immigration, and you typically keep the original 3-business-day timeline.
The issued PDF cannot be edited, so this needs a corrected re-file. Reach out with your reference details and the correction, and a clean application is lodged with the right information, then reissued as a fresh printable PDF by email. Through us, a flagged correction comes with free resubmission, so you are fixing the document, not buying a second one. Do this as soon as you spot the error — the earlier you start, the more runway you have before your flight.
Check it against the list in the previous section. If it is an address, a slightly-off arrival date, or a dropped middle name that still matches your passport bio line, you can usually leave it. If you would rather be certain, send a message and ask — confirming a non-issue costs nothing and beats traveling with a nagging doubt.
Whichever situation you are in, the fastest resolutions happen when you supply the correct passport details up front rather than describing the problem in prose. Reach US-timezone support and they can tell you in one exchange whether your error is fixable in place, needs a re-file, or can be safely ignored. If you have not submitted yet and want to avoid all of this, our roundup of the application mistakes US travelers make most often is the checklist to read before you hit submit.
The cheapest correction is the one you make before you fly. When your approved eVisa PDF arrives, do not just file it — spend two minutes proofreading it against your passport, open in front of you. This is the single habit that keeps US travelers out of a gate hold.
Read the four entry-critical fields off the PDF and check each one against the passport itself, not against your memory. Surname spelled letter for letter. Given names in the same order. Passport number digit for digit — pay attention to where a zero might read as the letter O, or a 1 as a letter I, because those are the transpositions that slip through. Date of birth in the same day-month-year your passport shows. Nationality reading as United States. If all four match, you are clear, regardless of any minor cosmetic difference elsewhere.
Do this proofread the day the PDF arrives, not the night before your flight. Catching a passport-number transposition with a week of runway means a calm re-file inside the normal window. Catching it at 11 p.m. before a 6 a.m. departure means a scramble. The error is identical; only the timing changed, and the timing is the part you control.
Print two copies of the corrected, final PDF once it checks out, and keep one in your carry-on separate from your passport. US travelers occasionally get asked for the printout even when a digital copy is on a phone, so the paper backup removes one more variable at the kiosk. For the full picture of which timing gives your application the most margin, work back from your flight date and start early.
A wrong detail on your Cambodia eVisa is almost always a time problem, not a money problem. Confirm whether you have been approved yet. If you are still processing, reply with the correct passport details now and keep your timeline. If the PDF is already issued, a material error needs a clean re-file rather than an edit — and through us, that correction is reissued free as a new printable PDF inside the same 3-business-day window.
Focus your worry where it counts: full name, passport number, date of birth, and nationality. Those four are what Cambodian Immigration matches at the gate. Address, arrival date, and a dropped middle name rarely matter. Proofread the approved PDF against your passport the day it arrives, and you turn a potential gate emergency into a two-minute desk task.
