Troubleshooting Payment Issues When Applying for Vietnam Visa Online

Last Update: Wednesday November 12, 2025

Applying for a Vietnam visa online is designed to be a simple and convenient process. However, sometimes applicants encounter payment issues that can interrupt or delay their Vietnam eVisa application. Common error messages such as “Vietnam eVisa payment failed” or “payment declined Vietnam visa” can be frustrating — especially when you’re in a hurry to complete your visa submission before your trip.

In this detailed guide, we’ll explain the most common problems paying for Vietnam visa online, what causes them, and most importantly, how to fix Vietnam visa payment errors quickly and successfully.

Why Do Vietnam Visa Payment Issues Happen?

The online visa payment system is linked to international payment gateways and banks that require security verifications. While this ensures safety for your transaction, it can also create obstacles if there’s a mismatch in your information, insufficient funds, or a missing security step.

Below are the three most frequent causes of Vietnam eVisa payment failed messages — along with clear instructions on how to fix them.

1. Incorrect Card Information

One of the most common reasons for Vietnam visa payment issues is entering incorrect card information during checkout. Even a small typing error can cause your payment to be declined automatically by the system.

Common Mistakes Include:

• Incorrect card number (missing or extra digits)

• Wrong expiry date

• Typing error in the CVV or CCV number (the 3-digit code on the back of your card)

• Using a cardholder name that does not match the one registered with your bank

How to Fix:

• Double-check your card number and expiration date before submitting.

• Make sure your CVV number is correct.

• Use the exact cardholder name as it appears on the card.

• If possible, try another card if you continue to receive an error message.

Pro tips: Some prepaid cards, corporate cards, or regional bank cards may not work for international payments. In that case, use an internationally accepted credit or debit card such as Visa, MasterCard, or American Express.

2. OTP (One-Time Password) Not Entered

Most international payment systems use 3D Secure authentication, which requires you to confirm your payment via a one-time password (OTP) sent by your card issuer. This is an important step to verify that the card owner is authorizing the transaction.

However, many travelers overlook this part, especially when traveling abroad.

Why OTP Issues Happen:

• You may not notice the OTP notification if it’s sent via SMS.

• If you’re using an eSIM or have replaced your regular SIM card while traveling, you may not receive the SMS from your bank.

How to Fix:

1. Once you reach the payment page, keep an eye on your phone for the OTP message from your bank.

2. If you’re using a travel eSIM or a temporary phone number, insert your original SIM card again so that your bank can send you the OTP.

3. If you still don’t receive it, contact your bank to confirm an alternative OTP delivery method.

Note: Without the OTP verification, the payment cannot be completed — even if your card and account are valid. Always confirm the OTP step before assuming there’s a technical error.

3. Insufficient Balance or 3D Security Not Confirmed

Another frequent cause of Vietnam eVisa payment failed is insufficient balance or unverified 3D security.

Even if you have funds available, some banks automatically block international transactions for security reasons unless you have pre-approved online payments.

Possible Causes:

• Your available balance is not enough to cover the payment.

• Your 3D Secure (Verified by Visa / MasterCard SecureCode) has not been activated.

• The bank temporarily blocked your card for suspected international activity.

How to Fix:

1. Check your account balance to ensure there are sufficient funds.

2. Enable 3D Secure verification through your bank’s mobile app or customer service.

3. If you are using a new card, make sure it’s activated for international payments.

4. Contact your card issuer or bank to authorize the transaction manually.

5. If your card still doesn’t go through, try another card or payment method.

Additional Tips to Prevent Vietnam Visa Payment Problems

To ensure a smooth and successful payment process when applying for your Vietnam eVisa, follow these recommendations:

1. Use a Stable Internet Connection

Avoid making payments over weak Wi-Fi networks or VPNs. Interrupted connections can cause incomplete transactions or double charges.

2. Do Not Refresh the Page

Once you click “Pay,” do not close or refresh the browser until the confirmation message appears. Doing so may cancel your transaction before it’s processed.

3. Check with Your Bank Before Traveling

If you’re applying from abroad, inform your bank that you’ll be making an international online transaction. This helps avoid automatic fraud prevention blocks.

4. Keep a Record of Payment Attempts

If a payment fails, take a screenshot of the error message and note the time. This helps our Vietnam-IMMI.org support team assist you faster in resolving the issue.
