What it is

The notice discloses that Amazon shares advertising identifiers (cookies, device identifiers, or cryptographic codes derived from email addresses) and ad effectiveness estimates with third-party ad companies, and that some of those ad companies may use this information to serve ads from advertisers other than Amazon.

This analysis describes what Amazon Marketplace's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability.

ConductAtlas Analysis

Why it matters (compliance & governance perspective)

This provision establishes a data flow from Amazon to third-party advertising partners that may extend beyond Amazon's own advertising ecosystem, as the notice states that some ad companies may use shared identifiers to serve ads from other advertisers. This data flow may require evaluation under CCPA cross-context behavioral advertising opt-out requirements and similar state frameworks.

"
We provide ad companies with information that allows them to serve you with more useful and relevant Amazon ads and to measure their effectiveness. We never share your name or other information that directly identifies you when we do this. Instead, we use an advertising identifier like a cookie, a device identifier, or a code derived from applying irreversible cryptography to other information like an email address. For example, if you have already downloaded one of our apps, we will share your advertising identifier and data about that event so that you will not be served an ad to download the app again. While we do not share your specific shopping actions like purchases, product views, or searches with ad companies, we may share an advertising identifier and an estimate of the value of the ads they show you on our behalf so they can serve you with more effective Amazon ads. Some ad companies also use this information to serve you relevant ads from other advertisers.
