Multi-Factor Authentication for International Bank Cards

All local Korean credit cards require Multi-Factor Authentication (MFA) when used for the first time on Amazon

If you're using your Korean credit card for the first time on Amazon, we direct you to an identity and carrier verification form. The information you input on this form allows the card issuer to authenticate the card and the user. There is no additional charge for this authenticate process. The identity and carrier verification form appears after selecting "Place Your Order" on the order summary page.

To authenticate your credit card, you'll need the following information:

  • Your Date of Birth.
  • The first two digits of your four-digit credit card password (not the expiration date or CVV/CVN).
  • Your mobile phone number.
  • Your business registration number (for corporate owned cards with the corporation name as the cardholder).

After you complete the authentication process, we redirect you back to Amazon. You only need to complete the multi-factor authentication process once per credit card.


  • You'll need to know whether a person or corporate entity owns the card. If a corporate entity owns the card, check the BRN checkbox on the carrier verification page.
  • If you have lost or forgotten your four-digit credit card password, contact the issuer of the card.
