What should you do if your card gets blocked in Thailand

Preparation & Essentials

3 min read

First of all, “don’t panic.”

This is a common security procedure used by banks. When they detect suspicious or unusual activity—especially in a foreign country—they may temporarily block or freeze your card.

The good news is that it can usually be resolved through a few simple steps.

Immediate Fix

Many banks, such as Revolut, Monzo, Chase, or Charles Schwab, allow users to unfreeze their cards directly through their mobile apps.

You can simply toggle your card back on if it was blocked due to a minor security flag (e.g., a foreign ATM transaction)
This fix is usually instant

Contacting Your Home Bank

If the issue is not resolved through the app:

Call your bank using the number printed on the back of your card or available on the bank’s website
Inform the representative about your situation and your stay duration in Thailand
Some blocks automatically lift after 24 hours, but you can request a temporary unblocking
You may need to verify your identity before the card is reactivated

The Alternate

If your card is still blocked after trying the above options, consider these alternatives:

Use cash if you already have some
Use a second card, if available
Ask a family member or friend to send money or pay on your behalf

Note: You cannot unblock a foreign card at Thai banks. However, you may request a cash advance over the counter in some cases.

Lesson Taken

Always carry at least two cards from different banks
Keep some emergency cash hidden securely in your luggage
Inform your bank before traveling to Thailand and provide your travel dates

Tips

Tip No.1:
If your card is retained by a Thai ATM, it is your responsibility to visit the bank branch to retrieve it. Many banks destroy retained cards after a certain period.

Tip No.2:
If your card is blocked for purchases, it may still work at ATMs. Try withdrawing cash if possible.
