Summary:
Maria Santos learned the hard way that a single digit error could derail an entire vacation. Standing at Toronto Pearson's check-in counter, she watched her family's dream trip crumble when airline staff couldn't match her eTA to her passport. One wrong number in her Electronic Travel Authorization application meant no boarding pass, no flight, and thousands in lost bookings. If you've entered an incorrect passport number on your eTA application, you're facing a travel emergency that requires immediate action. This comprehensive guide reveals exactly what happens when passport numbers don't match, the urgent steps you must take to fix the problem, and how to prevent this costly mistake from destroying your Canadian travel plans.
🔑 Key Takeaways:
- Wrong passport numbers will prevent you from boarding your flight to Canada
- You cannot correct an existing eTA - you must submit a completely new application
- Airlines may only discover the mismatch at check-in, potentially stranding you at the airport
- Last-minute eTA applications aren't guaranteed approval before your departure
- The passport number must match exactly - even one wrong digit invalidates your authorization
The Moment Everything Goes Wrong
Picture this: you're standing at the airline counter, boarding passes printed, luggage checked, and excitement building for your Canadian adventure. Then the gate agent frowns at their computer screen. "I'm sorry, but your eTA doesn't match your passport number. You won't be able to board this flight."
This nightmare scenario happens more often than you'd think. When you enter an incorrect passport number on your Electronic Travel Authorization application, you're essentially creating a travel document that doesn't belong to you. The Canadian government has no way to verify your identity, and airlines are legally required to deny you boarding.
What Happens When Numbers Don't Match
The consequences of entering a wrong passport number extend far beyond a simple paperwork error. Here's the cascade of problems you'll face:
At the Airport: Airlines use automated systems that cross-reference your eTA with your passport. If these numbers don't align perfectly, their system flags your booking as invalid. You'll discover this problem at the worst possible moment - when you're trying to check in or board your flight.
No Boarding Permission: Immigration and airline staff have zero flexibility on this issue. Even if it's obviously a typo, even if you can prove your identity through other means, the rules are absolute. Wrong passport number equals no travel to Canada.
Immediate Financial Impact: You'll face costs for rebooking flights, potentially losing non-refundable tickets, hotel reservations, and planned activities. Travel insurance rarely covers mistakes in government applications.
Your Emergency Action Plan
If you've discovered a passport number error in your eTA application, time is your enemy. Here's your step-by-step recovery strategy:
Step 1: Verify the Error Immediately Check your eTA approval email against your actual passport. Look at the passport information page (the one with your photo) and compare every single digit. Don't assume you remember your passport number correctly - even frequent travelers make mistakes.
Step 2: Submit a New Application Right Away There's no correction process, no amendment option, and no customer service hotline that can fix this for you. You must submit a completely new eTA application with the correct passport number. The $7 CAD fee applies again, and processing times start from zero.
Step 3: Prepare for Processing Delays While most eTAs process within minutes, some applications require manual review that can take days or even weeks. If you're traveling soon, you're gambling with your departure date. Consider postponing travel if you're within 72 hours of departure.
Step 4: Document Everything Keep screenshots of your original application, the approval email, and your new application. If you need to contact airlines about rebooking, this documentation proves you're actively resolving the issue.
The Verification Process That Could Save Your Trip
Before you submit any eTA application, follow this bulletproof verification system:
The Double-Check Method: After entering your passport number, immediately open your physical passport and read each digit aloud while looking at your screen. This catches transposition errors and typos that silent reading often misses.
The Fresh Eyes Approach: Have someone else read your passport number from the document while you verify it matches your application. Two people catching the same error is statistically unlikely.
The Photo Backup: Take a clear photo of your passport information page before starting your application. This gives you a reference that won't close accidentally like a physical passport might.
Understanding the Technology Behind the Problem
Your eTA isn't just a travel permission - it's a digital key that must fit perfectly with your passport. When you board a flight to Canada, airline systems perform real-time verification with Canadian immigration databases.
This automated process checks dozens of data points, but passport number matching is the first and most critical step. If that fails, the system doesn't even verify your name, nationality, or other details. It simply returns a "no match" result that grounds your travel plans instantly.
Prevention Strategies for Future Applications
Smart travelers develop systems to avoid passport number errors entirely:
Create a Passport Information Sheet: Type out all your passport details in a document and save it securely. Copy and paste from this verified source rather than retyping numbers each time you apply for travel documents.
Use the Passport While Applying: Keep your passport open to the information page throughout the entire application process. Don't rely on memory or handwritten notes.
Apply Early, Verify Often: Submit eTA applications at least two weeks before travel. This buffer allows time to catch and correct any errors without jeopardizing your trip.
The Cost of Getting It Wrong
Beyond the obvious travel disruption, passport number errors create a domino effect of expenses:
- New eTA application fee: $7 CAD
- Flight change or rebooking fees: $200-$800 per person
- Hotel cancellation penalties: Often 50-100% of booking value
- Lost activity bookings: Tours, restaurants, events rarely offer full refunds
- Extended parking or accommodation: If you're stuck at your departure city
For a family of four, a simple digit error can easily cost $2,000-$5,000 in additional expenses and lost bookings.
When Time Is Running Out
If you're within 24-48 hours of departure and just discovered a passport number error, you're in crisis mode. While most eTAs process quickly, you can't guarantee approval in time for your flight.
Consider these emergency options:
- Contact your airline about rebooking to a later date before submitting your new eTA
- Review travel insurance policies for coverage of government document errors
- Prepare backup plans for extended stays if your new eTA doesn't process in time
The Bottom Line on eTA Passport Numbers
Your Electronic Travel Authorization is only as good as the passport number it's linked to. Canadian immigration systems are unforgiving about mismatches, and airlines have no authority to override these restrictions.
The moment you realize there's an error, you're racing against time to submit a new application and hope for quick processing. Your best defense is careful verification during the initial application process, treating your passport number entry with the same precision you'd use for banking information.
Remember: there are no shortcuts, no exceptions, and no appeals process. Get the passport number right the first time, or prepare for the expensive consequences of starting over.
FAQ
Q: What exactly happens at the airport if my eTA has the wrong passport number?
When you arrive at the airport with an incorrect passport number on your eTA, the airline's automated check-in system will immediately flag a mismatch during document verification. The system cross-references your eTA with your physical passport in real-time, and even a single wrong digit triggers an automatic denial. Gate agents have no override authority - they're legally required to deny boarding regardless of circumstances. You'll discover this problem at the worst possible moment: either during online check-in (which will fail), at the check-in counter, or at the boarding gate. The airline staff cannot make exceptions, even if the error is obviously a typo or if you can prove your identity through other documents. This inflexibility exists because airlines face substantial penalties for transporting passengers without proper authorization to Canada.
Q: Can I fix or correct the wrong passport number on my existing eTA application?
No, there is absolutely no correction, amendment, or editing process for eTA applications once they're submitted. The Canadian government doesn't offer customer service corrections, phone support for changes, or any method to modify existing applications. You must submit a completely new eTA application with the correct passport number, paying the $7 CAD fee again. Your original eTA with the wrong number becomes permanently invalid and cannot be used for travel. The new application goes through the entire processing cycle from the beginning, meaning you'll receive a new eTA number and approval email. Most applications process within minutes, but some require manual review that can take several days or weeks. This is why discovering the error close to your departure date creates a travel emergency with no guaranteed resolution timeline.
Q: How can I prevent passport number errors when applying for my eTA?
Implement a multi-step verification system to eliminate errors entirely. First, use the "read-aloud method" - after typing your passport number, open your physical passport and read each digit aloud while checking your screen. This catches transposition errors that silent reading misses. Second, employ the "fresh eyes approach" by having another person read your passport number from the document while you verify the application screen. Third, take a clear photo of your passport information page before starting your application as a reference that won't accidentally close. Create a secure digital document with all your passport details and copy-paste from this verified source rather than retyping. Always keep your passport open to the information page throughout the entire application process, and apply at least two weeks before travel to allow correction time if needed.
Q: What are the total costs if I need to fix a wrong passport number close to my departure date?
The financial impact extends far beyond the $7 CAD new eTA fee. Flight change fees typically range from $200-$800 per person, and last-minute rebooking can cost significantly more. Hotel cancellation penalties often amount to 50-100% of your booking value, especially for non-refundable rates. Pre-booked tours, restaurant reservations, and activities rarely offer full refunds for cancellations within 48-72 hours. Additional costs include extended parking at your departure airport, potential overnight accommodation if you're stranded, and meal expenses during delays. For a family of four, these combined expenses easily reach $2,000-$5,000. Travel insurance typically doesn't cover errors in government applications, making you personally liable for all costs. The earlier you discover and address the error, the more flexibility you have to minimize these financial penalties through airline goodwill policies and accommodation provider understanding.
Q: How long does it take to get approval for a new eTA application when fixing a passport number error?
While the majority of eTA applications process within minutes, there's no guarantee of immediate approval, especially when you're in crisis mode. Applications requiring manual review can take anywhere from several days to multiple weeks, depending on factors like your travel history, nationality, and current processing volumes. The Canadian government's official processing time is "minutes to days," but they recommend applying well in advance specifically because of potential delays. If you're within 72 hours of departure, you're essentially gambling with your travel dates. Applications submitted on weekends or holidays may experience longer processing times due to reduced staffing. Rush processing or expedited services don't exist for eTA applications - every submission follows the same queue regardless of your departure urgency. This unpredictable timeline is why passport number errors discovered close to travel dates often result in mandatory trip postponements rather than successful same-day corrections.
Q: Will airlines help me resolve eTA passport number mismatches or offer any flexibility?
Airlines have zero authority or flexibility regarding eTA passport number mismatches due to strict Canadian immigration enforcement and substantial penalties for non-compliance. Gate agents, supervisors, and even airport managers cannot override the automated system denials or make exceptions for obvious typos. The airline's computer system automatically blocks boarding when passport numbers don't match exactly, and staff are legally prohibited from bypassing these controls. However, airlines may offer rebooking assistance once you've submitted a corrected eTA application, potentially waiving change fees as a goodwill gesture if you explain the situation calmly and early in the process. Some carriers provide same-day rebooking to later flights if your corrected eTA processes quickly, but this depends on seat availability and route frequency. The key is contacting airline customer service immediately after discovering the error and before arriving at the airport, as options become extremely limited once you're at the gate facing a boarding denial.
