Booked Your Flight with One Passport but Want to Enter Vietnam with Another? What You Need to Know

Last Updated: November 14, 2026

Have you booked your flight using one passport but plan to enter Vietnam with another? This situation is common among travelers with dual nationality or multiple valid passports. However, using a Vietnam visa with two passports requires careful planning. Your airline booking, visa application and immigration documents must be coordinated to avoid check-in or entry problems.

Key Takeaways

Holding two valid passports does not automatically prevent you from traveling to Vietnam.
Choose the passport you intend to use for Vietnamese immigration procedures before applying for your visa.
Your Vietnam eVisa must correspond to the passport presented at immigration.
Foreigners holding multiple passports must use only one passport for entry, exit, transit and residence in Vietnam.
A flight ticket passport mismatch may be manageable, but you should confirm document-update procedures with your airline before departure.

Can You Book a Flight with One Passport and Enter Vietnam with Another?

Yes, in some situations, but you need to distinguish between your flight reservation and your immigration documents.

For example, imagine you hold both a British passport and an Australian passport:

You booked your flight using your British passport.
You plan to apply for a Vietnam eVisa using your Australian passport.
You intend to enter Vietnam using your Australian passport.

This may be manageable, provided your airline accepts the travel documents presented and your visa is valid for the passport used for entry.

However, there is an important legal requirement to understand.

Under Article 4, Clause 4 of Vietnam's Law on Foreigners' Entry, Exit, Transit and Residence, a foreigner holding more than one passport may use only one passport for entry, exit, transit and residence in Vietnam.

Therefore, you should choose the passport you intend to use for your entire stay in Vietnam and follow that choice consistently.

Which Passport Should You Use for Your Vietnam eVisa?

If you need a Vietnam eVisa, the most important rule is that the visa must correspond to the passport you will present when entering Vietnam.

The official Vietnam eVisa application asks for specific passport information, including:

Passport type.
Passport number.
Issuing authority.
Date of issue.
Expiry date.

The application also includes questions about whether you hold other valid passports and whether you have multiple nationalities.

This means travelers with two passports should provide accurate information rather than assuming that only one passport matters during the application process.

Example: Two Passports, One Vietnam eVisa

If Passport B is the passport used for your Vietnam eVisa, use Passport B when entering and exiting Vietnam.

Do not present Passport A as a substitute for Passport B at Vietnamese immigration.

What If Your Flight Ticket and Passport Details Do Not Match?

A flight ticket passport mismatch can cause confusion, but not every difference means your ticket is invalid.

It is important to distinguish between two types of information.

Passenger name versus passport number

Passenger name

The name on your flight ticket should generally correspond to the travel document you present. If your two passports show different name formats or spellings, check with your airline before departure.

Passport number

Some airlines allow passengers to update passport information after booking, while others collect or verify document details during online check-in or at the airport.

Therefore, having booked with one passport number does not automatically mean you must use that same passport for every part of your journey.

However, you should confirm the airline's requirements before traveling.

What should you do?

Check the passenger name on your booking against both passports.
Contact your airline and explain that you hold two valid passports.
Ask whether you can update the travel document information.
Confirm which passport should be presented at check-in.
Carry both passports when traveling, if permitted and appropriate.

Important: Do not change your ticket name or make a new booking without first checking with your airline. A passport information update and a passenger name correction are not necessarily the same procedure.

Can You Enter Vietnam with a Different Passport from the One Used to Book Your Flight?

This depends on your nationality, visa status and airline requirements.

Consider three common situations.

Situation 1: Both passports are eligible for visa-free entry

If both nationalities qualify for Vietnam's visa exemption, you may have more flexibility in choosing which passport to use.

However, you should still:

Select one passport for Vietnamese immigration procedures.
Enter and exit Vietnam using that same passport.
Confirm that your airline accepts the travel documents presented.

Check the current visa exemption conditions for your nationality before departure.

Situation 2: One passport requires a Vietnam eVisa

For example, you hold:

Passport A: Eligible for visa-free entry.
Passport B: Requires a Vietnam visa.

If you choose Passport B and obtain a Vietnam eVisa, you must use Passport B for the corresponding entry and exit procedures.

You should not assume that you can present Passport A at immigration and use the eVisa issued for Passport B as a backup.

If you decide to use Passport A instead, check its entry eligibility and discuss any existing visa application or approval with the appropriate authorities.

Situation 3: You have already received a Vietnam eVisa using the other passport

This is where travelers need to be particularly careful.

Suppose you booked your flight using Passport A but obtained an approved Vietnam eVisa using Passport B.

You should not simply switch to Passport A at the immigration counter.

Your approved eVisa contains the identifying information of Passport B. It is not automatically transferable to Passport A.

If you want to change the passport you will use, review the visa situation before departure and seek guidance on whether a new application is necessary.

What If You Hold Both a Vietnamese Passport and a Foreign Passport?

This situation is different from holding two foreign passports.

If you are a Vietnamese citizen who also holds another nationality, do not automatically follow the same visa procedures as foreign travelers.

Vietnamese citizens generally enter Vietnam using valid Vietnamese travel documents. If you intend to travel using your foreign passport, you should confirm the applicable entry requirements with the Vietnamese Embassy or Immigration Department before departure.

Consider the following:

Check whether your Vietnamese passport is valid for your travel dates.
Confirm the airline's requirements for passengers holding multiple nationalities.
Check whether you need to present your Vietnamese passport when entering Vietnam.
If you have already applied for a Vietnam eVisa using your foreign passport, seek advice before changing your intended travel document.

Do not assume that holding an approved Vietnam eVisa means you must enter Vietnam as a foreign visitor if you are also a Vietnamese citizen.

Your citizenship status and travel documents may affect the appropriate procedure.

What Should You Do Before Your Flight?

If you have already booked your ticket but want to use another passport, follow this checklist before departure.

Two-passport travel checklist

Check that both passports are valid.
Decide which passport you will use for Vietnam entry and exit.
Check whether that passport requires a Vietnam eVisa.
Make sure your eVisa details match your chosen passport.
Contact your airline about updating passport information.
Confirm that your passenger name meets the airline's requirements.
Carry both passports if appropriate for your circumstances.
Keep a copy of your approved eVisa accessible.

It is much easier to resolve a passport discrepancy before departure than to discover a problem at the airport.

If you are unsure which passport to use, do not submit another visa application or change your flight booking immediately. First, review your nationality, current visa status and airline requirements.

Frequently Asked Questions

Can I book a flight with one passport and enter Vietnam with another?

In some circumstances, yes. However, you must check airline document requirements and ensure that your visa or visa exemption corresponds to the passport used for entry.

Can I use my British passport to book a flight and my Australian passport for a Vietnam eVisa?

Potentially, yes. You should confirm with your airline whether the passport information can be updated or whether presenting both passports at check-in is sufficient. Use the Australian passport associated with your eVisa for Vietnam entry and exit.

Can I change the passport number on my flight booking?

This depends on the airline. Some airlines allow passengers to update passport information through their booking management system or at check-in. Contact your airline to confirm its specific procedure.

Can I use one passport to enter Vietnam and another to leave?

Foreigners holding multiple passports should use only one passport for entry, exit, transit and residence in Vietnam. Do not switch passports between entry and exit.

Do I need a Vietnam eVisa if one of my passports is visa-exempt?

Not necessarily. If one of your nationalities qualifies for visa-free entry, you may be able to use that passport instead of obtaining an eVisa, provided you meet all applicable conditions.
