With a North America Unified Account, you can conveniently switch in Seller Central between Amazon.com, Amazon.ca, and Amazon.com.mx seller tools to list products and manage orders in multiple marketplaces. You have the option to list in one, two, or all three of the available North American marketplaces.
The North America Unified Account allows you to more easily:
*Note: The single monthly Professional selling plan subscription fee is applied based on the Amazon marketplace to which you initially registered. For example, if you initially registered to sell on Amazon.com, your monthly subscription fee is listed on the Amazon.com Selling on Amazon Fee Schedule.
When managing your Amazon inventory across Amazon's United States, Canada, and Mexico marketplaces, it is important to understand the difference between the Global SKU and the marketplace-specific SKU in Seller Central.
A Global SKU uses a shared inventory pool between the United States, Canada, and/or Mexico. You can create a Global SKU by selecting "Existing Offer" when you go to create an offer in Seller Central. When using a Global SKU, the total amount of inventory applies to all marketplaces. For example, if you have 100 units of inventory, it will display that there are 100 units in United States, 100 units in Canada, and 100 units in Mexico. The 100 applies to all three countries and DOES NOT add up to a total of 300 units. If an item sells in Canada, then all marketplaces would show 99 units available.
If you are shipping an order yourself, you should use a Global SKU to manage inventory across the United States, Canada, and/or Mexico. Inventory fulfilled by Amazon is not eligible to list as a Global SKU. Note that if you change a Global SKU from seller-fulfilled to Amazon-fulfilled, this change will impact the SKU across every marketplace.
If you are shipping from the United States to Mexico, consider the following when choosing you shipping carrier: Not all shipping options deliver the transit speeds that Amazon customers worldwide have come to expect. For example, a recent study of orders fulfilled by sellers shipping from the United States to Mexico showed that approximately 69% of orders shipped via United States Postal Service (USPS), which uses Correos de México/Servicio Postal Mexicano (SEPOMEX) for delivery within Mexico, did not meet Amazon's international shipping transit time requirements. To provide a great customer experience on shipments from the United States to Mexico, we strongly recommend that you use other carriers (e.g., FedEx, DHL, UPS).
A marketplace-specific SKU is managed as a marketplace-level inventory pool, which means you will manage distinct pools of inventory across the United States, Canada, and Mexico. You can create a marketplace-specific SKU by selecting Unique Offer when you go to create an offer in Seller Central. The listing is managed separately in each marketplace for both inventory and pricing.
If you are using Fulfillment by Amazon, you can use a marketplace-specific SKU and manage your inventory in Amazon fulfillment centers in the United States, Canada, and Mexico as separate pools. Please note that inventory going to U.S. fulfillment centers should be shipped from the Amazon.com section of your North America Unified Account and vice versa for Canada and Mexico. For example, if you have a FBA listing on the Canada marketplace, your "Ships from" address must be in Canada.
