Register first and then upload products.

After the application is completed, Amazon will send a verification code to the registered email address of the agent that registered your trademark. Please obtain the verification code as soon as possible within 30 days and reply to the email for brand registration. As long as you provide the verification code and reply, you will receive a relevant email indicating that the brand registration has been successfully completed! Until this step, the brand registration is considered complete. After submitting to Amazon, the registration can be completed within 48 hours. After the registration is successful, you can upload products to the store without waiting for a long time.
