Good Morning, and thank you for posting on the Final Fantasy XIV Technical Support Forums.

This is a billing issue not a technical one, however, we may still be able to assist.

A 601 error is a billing error, meaning something is interfering with your payment method. It can be triggered by a few reasons such as the transaction being declined by the bank, incorrect card information, insufficient funds or the card being used on multiple accounts.

Since we cannot discuss personal information in a public setting, you will need to contact the Square Enix Support Center to get a specific answer.

The Support Center can be contacted via phone, chat or email support through the Square Enix Support Center website. Please use this link to direct you to the Final Fantasy XIV support website:

Please note live service is available Monday through Friday, 9:00 – 18:00, Pacific Time (Excluding holidays).

If you are having trouble paying for the subscription, you can purchase a Game Time Card (available on the Square Enix Online Store, Amazon, etc.). Since this is a code that you redeem, it will circumvent credit card blocks. Also, try not to force the transaction through, as multiple failed attempts can make the error worse.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
