To get the Prime badge as a seller, you must enroll in the AMZ Prime program for sellers. Go to your Seller Central account, navigate to the “Settings” menu, and click on “Fulfillment by AMZ.” Then click the “Edit” button next to “AMZ Prime” to enroll in the program. You must meet certain requirements, such as competitive pricing and shipping standards. The marketplace has strict seller requirements, and the program is not available in all countries. Additionally, there are fees associated with using the program.
