The Amazon registered brand registration number is obtained by submitting a brand registration application to Amazon and after review. This step is to protect the brand rights of the seller and ensure the legitimacy and uniqueness of the goods on the platform. To obtain a brand registration number, you first need to submit relevant information on Amazon's brand registration page, including brand name, trademark, product category, etc. Amazon will review the submitted information to verify the authenticity and legitimacy of the brand. Once the review is passed, Amazon will assign a unique brand registration number to the seller and associate it with the seller's account. With a brand registration number, sellers can enjoy a number of brand protection rights, such as preventing others from abusing or counterfeiting their own brands, and displaying brand logos and stories on the platform to enhance brand awareness and credibility. At the same time, Amazon will also provide a series of tools and resources to help sellers better manage and promote their own brands. Therefore, for sellers who want to build their own brands on Amazon, registering a brand and obtaining a registration number is a very important step.
