Hi @Seller_w0ZnecrIfL0wk,

First, let's check if you have a unified account for North America. Look at the marketplace selector in the top-right corner of Seller Central - does it show options for Canada and Mexico? You can learn more about checking your account status here: https://sellercentral.amazon.com/help/hub/reference/G201841950

If you see these options (unified account):

• You don't need to delete anything - just create listings only for the US marketplace
• Make sure you're in the US marketplace when creating listings (check the marketplace selector)
• For any existing listings in Canada or Mexico, you can either set their quantity to zero or delete them completely

Important: Check if you're using the Build International Listings tool:

• Go to Build International Listings (https://sellercentral.amazon.com/gp/global-selling/sync-offers)
• If you see active connections to Canada or Mexico, you can remove them:

• Select the marketplace you want to disconnect
• Click "Remove Connection" in the Connection settings
• Choose whether to keep or delete your offers in that marketplace
• If you don't see the marketplace options in the top-right corner (separate account): You're already set up for US-only selling and don't need to take any action.
