us seller refers to a seller based in the United States who uses Amazon’s platform to sell products. US sellers can take advantage of Amazon’s vast customer base, logistics network, and advertising tools to grow their businesses. Being a US seller on Amazon also provides access to Fulfillment by Amazon (FBA), allowing sellers to store products in Amazon’s US-based warehouses, where they are picked, packed, and shipped directly to customers. US sellers benefit from Amazon’s brand recognition and the ability to reach both domestic and international markets.
