Square Enix are shifting to new internal systems and services that require all of their customers to properly identify their current residence in order to access new products and services. One consequence of this is that Members residing outside of the United States and Canada will not be able to access their existing North America SQUARE ENIX MEMBERS accounts, including MEMBERS Points, after August 31, 2010 2:00am PDT. New accounts may be available in your proper territory.
On September 22, along with the official launch of FINAL FANTASY XIV's service, the Square Enix Account Management System will be significantly updated, adding a variety of payment features and more.
Due to these upgrades, current Square Enix Account users will need to register their country of residence the first time they log in to the Square Enix Account Management System after August 31, 2010 2:00am PDT.
