In order to get brand ungated on Amazon, you will need to provide the following:
-A letter on company letterhead signed by a corporate officer authorizing Amazon to contact them regarding your account
-Your company's website URL
-Your business address, telephone number, and email address
-The ASINs (Amazon Standard Identification Numbers) of the products you want to list under your brand name. If you don't have these yet, you can find them by searching for your product on Amazon.com and looking at the URL of the listing page. The ASIN is the string of letters and numbers that appears after dp/ in the URL. For example, if the URL is http://www.amazon.com/gp/product/B00123456 then the ASIN is B00123456.
