Once you reached a certain rating and kept it for a certain number of games (you can read full eligibility rules here), you can claim your FOA title.
Arena checks if you reached the title level automatically and will display the ‘Claim title’ button in the menu.
Once you click ‘Claim the title’, you will be asked to pay the one-time official FIDE title fee — you can pay it with any credit card 💳 or via PayPal. Once you made the payment, the title will be awarded. You will get the official FIDE certificate, and your FIDE profile on both the Arena and FIDE website will be updated.
♟Tip: Only Pro-members can qualify for the FOA titles.
