Identifying the Symptom: Invalid Country Code

When integrating Adyen into your application, you might encounter an error message stating "Invalid Country Code". This error typically occurs during the payment processing phase, where the country code provided in the request is not recognized or supported by Adyen.

Common Scenarios

• During checkout, the transaction fails with an error message.
• The payment request is rejected due to an invalid country code.

Exploring the Issue: What Causes the Invalid Country Code Error?

The Invalid Country Code error arises when the country code specified in the payment request does not match the expected format or is not supported by Adyen. Country codes are typically represented in ISO 3166-1 alpha-2 format, which consists of two letters (e.g., US for the United States, GB for Great Britain).

Root Causes

• Typographical errors in the country code.
• Use of outdated or unsupported country codes.
• Incorrect mapping of country codes in the application logic.

Steps to Fix the Invalid Country Code Issue

To resolve the Invalid Country Code error, follow these actionable steps:

Step 1: Verify the Country Code

Ensure that the country code provided in the request is in the correct ISO 3166-1 alpha-2 format. You can refer to the ISO official website for a complete list of valid country codes.

Step 2: Update Application Logic

Review your application's logic to ensure that the country code is being correctly mapped and passed in the payment request. Check for any hardcoded values or incorrect mappings that might lead to an invalid code being sent.

Step 3: Test with Supported Country Codes

Conduct tests using known valid country codes to ensure that the issue is resolved. You can use test environments provided by Adyen to simulate transactions and verify the correct handling of country codes.
