We make no email requirements other than you must be able to recieve our email confirmation when creating your account. In some countries, internet service and mobile providers may provide email addresses that are restricted to certain types of messages within their network or platform. If you don't receive the "email confirmation" email when registering, and the message (hopefully!) didn't end up in your spam folder, this might be the case for you. Simply try a different email address from a less restrictive provider.
For events listed in USD, we accept Visa, MasterCard, American Express, JCB, Discover, and Diners Club.
For events listed in JPY, we accept Visa, MasterCard, and American Express.
If your card brand is not accepted by the event you'd like to register for, we recommend purchasing a prepaid Visa or MasterCard to complete your registration.
sport.io will never charge registration fees to athletes. Ever.
That being said, your credit card company may charge international transaction fees or currency conversion fees for events purchased in different countries or currencies than the card was issued. Please contact your credit card company for questions or concerns about daily exchange rates and/or any fees they may charge you for international transactions.
