Per our relationship with Stripe, Seller Profiles must establish a country. Per Stripe, "The country must be the country the account holder resides in or that the business is legally established in."
If you are an individual, this is typically your country of residence and where you file your taxes.
If you are a business, this is the country in which your business operates.
Please Note - once you have created your Seller Profile, unfortunately you cannot change your country yourself. Please contact support for assistance.
