When you register to sell in the U.S. on Amazon.com, you will need to provide a valid credit card, phone number, and tax information. For taxes, you will be required to go through an online step-by-step interview that will determine whether you will need to complete a W-9 form (as a U.S. taxpayer) or a W-8BEN (as a non-U.S. taxpayer). When you register to sell in Canada or Mexico, on Amazon.ca or Amazon.mx, you will need to provide a valid credit card, phone number, and tax information.
North America Unified Account
In North America, we have simplified managing your business across the United States, Canada, and Mexico marketplaces. The North America Unified Account enables you to create and manage product offers in the U.S., Canada, and Mexico. You control what you sell and where you sell from a single seller account interface.
When you sign up to sell on Amazon.com, Amazon.ca, or Amazon.mx, your seller account is automatically enabled to sell in both marketplaces. You can switch between marketplaces using the marketplace switcher in Seller Central. This allows you to list products and manage orders in each marketplace.
As a Pro Seller, you will only pay subscription fees corresponding to the marketplace where you first registered to sell. For example, if you registered to sell on Amazon.com, you will pay the subscription fees for that marketplace. If you decide to sell on Amazon.ca, you will not pay additional subscription fees. However, for all per-item sales, you will pay the fees applicable to the marketplace in which the item was sold.
In order to sell across the U.S., Canada, and Mexico, you will need to create listings on Amazon.com, Amazon.ca., and Amazon.mx. Please note that creating offers in the first marketplace where you register (e.g., Amazon.com) and begin selling does not automatically populate offers in the other marketplace (e.g., Amazon.ca); if you want to sell in all three marketplaces, you will need to create offers in each marketplace.
Finally, when setting up a North American Unified Account, you’ll need to provide a bank account in one of the countries supported by Amazon. Currently, Amazon supports U.S., Canadian, and Mexican bank accounts, as well as bank accounts in other countries across the globe.
