To use a serial code, please follow these steps:
Browse to http://game.granbluefantasy.jp/#serialcode
Enter the 16-digit code into the provided field
If the code is correct, you will see a message that says "Serial Code Entry Completed" and the loot will appear in your crate.
If you encounter an error during the entry process, please see the following instructions:
Incorrect Code Entry: If the entry code is incorrect, please contact our support team for assistance. To speed up the process, please include a screenshot of the code entry field. We will send a replacement code once we have verified the issue.
2. Code Already Used: If you receive an error message that says "The entry code has been used," please contact our support team. We will investigate the issue and send a replacement code if it was our mistake.
3. Maximum Usage Reached: Most loot can only be claimed once per account, so you may receive an error message if the number of uses for the code has been reached.
4. Code Entry Limit Reached: If you enter an incorrect code three times within a certain period, your account may be restricted from entering more codes for one hour.
We hope this guide has been helpful for you. If you have any further questions or concerns, please don't hesitate to contact our support team for assistance.
