To get brand approval on Amazon, you need to enroll in the Amazon Brand Registry program. Brand Registry helps you protect your registered trademarks on Amazon and gives you additional tools and features to enhance your brand presence. Here's an overview of the process:

1. Verify Eligibility: To be eligible for brand approval, you must have an active registered trademark for your brand that meets Amazon's requirements. Trademarks should be issued by the intellectual property office in the country or region where you seek brand approval.

2. Create an Amazon Seller Account: If you don't have an Amazon seller account, you need to create one. Choose either an Individual or Professional selling plan, depending on your business needs.

3. Enroll in Amazon Brand Registry: Once you have an Amazon seller account, you can apply for brand approval through the Amazon Brand Registry program. Provide the necessary information, including your registered trademark details and brand images.

4. Wait for Approval: After submitting your application, Amazon will review it for eligibility. The review process can take several weeks, so be patient. During this time, Amazon may contact you for additional information or clarification.

5. Utilize Brand Registry Tools: Once approved, you gain access to various tools and features to protect your brand and enhance your product listings. These include Brand Analytics, Enhanced Brand Content, A+ Content, Sponsored Brands, and more.

It's important to note that each country's Amazon marketplace has its own Brand Registry, so you'll need to enroll separately for each marketplace where you want brand protection.
