At this time, Amazon Attribution is available to vendors in the United States with limited availability in the United Kingdom. Additionally, seller brand owners operating in the US are able to register through Seller Central.
Brands are required to initiate sign up requests. Please submit one request per country, including country-specific vendor codes with each. Once access is granted, additional users such as agency partners can be added. If you are an agency, please direct the brand(s) you work with to this page to sign up.
Once you have signed up, you can expect an invite email with your new Amazon Attribution entity within two weeks. You will then be able to access Amazon Attribution through the Amazon DSP.
