how to start an amazon account is simple and requires only basic information like your name, email, and payment details. If you’re planning to sell, you’ll need to upgrade to a seller account and provide additional information such as tax ID and business address. Creating a buyer-only account allows you to shop and review products, while a seller account gives access to inventory tools, order management, and analytics. Starting with accurate info helps avoid account issues down the road and ensures a smooth setup process.
