Linking & Identification · Company practice
Purchased Music may carry Unique Identifiers that can identify you as the owner, as some record companies require
Some record companies require Amazon to insert identifiers in the metadata that comes with Purchased Music from them. These Unique Identifiers uniquely identify the music as Content you received from Amazon and may contain information that can identify you as the owner of the Purchased Music. Examples given are a random number assigned to your order or copy, the purchase date and time, an indicator that it was downloaded from Amazon, codes identifying the album and song (UPC and ISRC), Amazon's digital signature, and an identifier showing whether the audio has been modified. Content sold with these identifiers is marked on its product detail page, and the identifiers do not affect playback.

Qualifications & exceptions
- Identifiers are inserted only for Purchased Music from record companies that require them.
- The examples are "for example", not a full list; the page says the identifiers "may" contain information that can identify you.
Not stated here
- The page does not say who can read the identifiers, whether they are shared beyond what section 4.2 describes, or how long they stay in a file.
Cross-references
- contrast (model-proposed): Amazon may share postal code and listening and viewing history with record companies, in a way not identifiable to you — contrast: Section 4.2 says information given to Content providers is provided in a manner not identifiable to you, while section 4.3 says Unique Identifiers in Purchased Music can identify you as the owner. The page does not say whether the identifiers are part of what is shared with Content providers.
