The short answer: an airline can only see an eTA that is linked to the exact passport you hand over, so “eTA not found” almost always means a passport mismatch (a typo, a renewed passport, the wrong one of two passports) or an application that has no decision yet. Check the passport number in your approval email against your passport, then check your eTA status with your application number and passport details; if the eTA really is tied to a different passport, you have to apply again, and if the new decision doesn’t come in time, the flight has to be rebooked. get-eta.com is a paid private service, separate from the Government of Canada.
Most of these cases come down to a single digit or a single document. If you have never looked up your result before, what each eTA status result means explains the difference between approved, pending and refused. If you got a new passport after approval, why a renewed passport needs its own eTA covers that case in full. The sections below start from what you see at the airport and work backwards to the cause.
How does the airline check your eTA at check-in?
The airline employee scans your passport. The system then shows whether a valid eTA is attached to that passport. Nothing needs to be printed, because an eTA is an electronic record, not a document you carry. You are expected to present the same passport you used when you applied.
That is why the failure looks the way it does. The check is tied to the passport that is scanned, so if the passport data differ even slightly from the application, no eTA shows up. Staff may describe this as “eTA not found” or “no eTA on file”, but the underlying problem is the same in every case: the passport in front of them and the passport on the eTA do not match, or no decision exists yet.
Why does the airline say “eTA not found”?
There are six common reasons. The table shows what you are likely to see, what to do first, and whether the airport itself can realistically fix it.
| What you see | Most likely cause | What to do now | Can it be fixed at the airport? |
|---|---|---|---|
| Not found, and the passport number in your email differs from the passport by one character | Typo in the passport number or the country code | Apply again with the correct data | Only if a new eTA is approved before check-in closes |
| Not found, and you have a newer passport than the one you applied with | Passport renewed after approval | Apply again with the new passport | Only if a new eTA is approved before check-in closes |
| Not found, but you hold two passports | You are travelling on the other passport | Check in with the passport used on the application, or apply for the other one | Yes, if you check in with the passport you applied with; otherwise only if a new eTA is approved before check-in closes |
| Not found, and you are a Canadian citizen with another nationality | A dual citizen cannot use an eTA | Travel on a valid Canadian passport (Canadian-U.S. citizens may also use a U.S. passport) | Only if you have that passport with you |
| Not found, and you never received an approval email | The application still has no decision | Check the status with your application number | Not until a decision is issued |
| The online check-in form rejects you, but you believe you are approved | Data mismatch or no decision yet | Verify the status, then go to the counter with the right passport | Depends on the cause above |
None of these is guaranteed to be solved on the spot, so the practical goal is to work out which row applies to you within the first few minutes.
What if the passport number or country code on your eTA is wrong?
An eTA cannot be edited after submission. If the number or the country of issue you entered differs from the passport, the only route is a new application with the correct data. The application form itself warns that a wrong passport number or country code can stop you boarding, and that an error is often discovered only at the airport.
The most frequent slip is swapping the letter O and the digit zero, or misreading a character printed in a small font. For more on how to tell them apart, see how to avoid confusing 0 and O in a passport number. When you re-enter the data, copy it from the printed page of the passport, not from memory or an old message.
What if you renewed your passport after getting the eTA?
A new passport means a new eTA. The old approval stays attached to the old passport number, so the airline’s system shows nothing for the new one. Having the old approval email in your inbox makes no difference, because the scan reads the passport and not the email. If you notice this before travelling, apply again with the new passport as early as you can. If you only notice at the counter, treat it like the typo case above: a new application is the only fix.
What if you hold two passports?
Two foreign passports
If both passports are from countries whose citizens need an eTA, use the one you applied with and present it at every stage of the journey. Checking in with the other passport is a classic cause of a failed lookup, because the scan finds nothing linked to it. If you would rather travel on the second passport, it needs its own eTA.
Canadian dual citizen
Canadian citizens, including dual citizens, are not eligible for an eTA and must fly to Canada on a valid Canadian passport. The one exception is a person who is both a Canadian and a U.S. citizen, who may use either the U.S. or the Canadian passport. For urgent cases, the Canadian government mentions a special authorization for dual citizens who have no Canadian passport, but it is a narrow route and not something to count on at a check-in desk. For the application side of this question, read which passport a dual citizen should apply with.
What if your eTA is still pending on the day you fly?
You should not travel to Canada until a decision has been made on the application. Most applicants hear back within minutes, but some requests need several days, which is why applying on the day of the flight is risky. If the decision arrives before the airline closes check-in, you can check in with that passport. If it does not, the flight has to be rebooked, because an approval that has not been issued cannot be found by any scanner.
What if you are only connecting through a Canadian airport?
An eTA is needed both to fly to Canada and to transit through a Canadian airport. A traveller heading from Europe to the United States via Toronto or Vancouver, for example, can be stopped at the first airport for exactly the same reasons described above. The causes, the table and the steps are identical; what differs is that your final destination is not Canada, so the eTA question catches people off guard.
Online check-in won’t accept your eTA. Should you go to the counter?
Some passengers first meet the problem on the airline’s app or website, when online check-in refuses to continue or asks them to see an agent. Treat that as a signal to verify the data, not as proof that something is wrong with the system. At the counter, the employee scans the passport itself, so the useful preparation is to confirm your status beforehand with your application number and passport details, and to have the passport you applied with in your hand.
What can you do at the airport right now?
- Take out the passport you applied with and compare its number with the one in your approval email, character by character. Check the country of issue as well.
- Check your eTA status using your application number and the details from that passport: its number, the country of issue, and the issue and expiry dates.
- If the eTA belongs to a different passport or contains a typo, start a new application from your phone, typing the data directly from the passport’s data page. You can apply for a Canada eTA again there.
- Tell the airline staff that a new application has been submitted.
- If there is still no decision when check-in closes, rebook the flight. Travelling without an approved eTA is not possible.

How do you avoid this on your next trip?
Three habits prevent most of these cases. First, check the passport number on the approval email the moment it arrives, rather than on the day you fly. Second, keep the eTA number in a safe place, because it is handy for status checks and enquiries, even though the airline does not need it to let you board. Third, apply again whenever the passport changes. The rules on what happens after you apply are worth a quick read before a trip, and an eTA does not guarantee entry to Canada in any case, because the border officer still makes the final decision.
The short version
- The airline scans your passport; the eTA is linked to that one passport and nothing needs to be printed.
- “eTA not found” usually means a typo, a new passport, the wrong passport or no decision yet.
- An eTA cannot be edited: a wrong passport number or country code means a new application.
- Canadian citizens, including dual citizens, travel on a Canadian passport instead of an eTA.
- Do not travel before the decision; some requests take several days.
- If the new decision does not arrive before check-in closes, rebook the flight.
FAQ
Can I board a flight to Canada without an eTA? No, if you are a visa-exempt foreign national flying in. U.S. citizens, U.S. green card holders travelling with their passport and green card, and Canadian citizens with a Canadian passport do not need one. Travellers who need a visitor visa board with the visa instead.
Do airlines check eTA status? Yes. The employee scans your passport, and the system shows whether a valid eTA is linked to it. You do not need to show a printout.
How can I check if I already have an eTA for Canada? Use the status checker with your application number, which starts with a V, and the details from the passport you applied with: number, country of issue, issue date and expiry date.
I can’t find my eTA number. Where can I find it? It is in the approval email you received after applying. The airline does not need the number to board you, but it is worth saving for future status checks.
What should I do if my eTA isn’t found at check-in? Compare the passport number in your email with your passport, check the status with your application number, and apply again if the eTA is tied to another passport or has a typo. If no decision arrives before check-in closes, the flight has to be rebooked.
