Go to Seller Dashboard → Settings → Shop. You can update your shop name, description, contact details and business address information available there.

Your shop name and description are public shop information. Some business details are more restricted: for example, the business country is fixed from your seller application. If your business has moved country, contact Support rather than trying to replace it in Shop settings.

Save Settings when you have finished. Required shop fields must be completed before the changes can be saved.
