Error code

Point to check



Paymethod, CardCountry mismatch


& any 3DS

The card attempting payment should be a card registered in the card brand's system to enable 3DS payment.


It happens when the customer's credit card company refuses the transaction, not our system.


It occurs when you try to make a payment with a payment method or a payment currency that is not set up in your account.


This is an error code that occurs when you try to pay more than 5 times you can pay in a month with the same IP. Testerkorea will prove this issue with PG company when we get request.


Appears when the customer's card issuer refuses the transaction, not our system


**What is the 3DS service?

3DS service is a system in which the customermust complete a self-certification process when making a payment is made.
