Identify the marking before reading it
A classic number, a black data tag, and a current NFC Authenticity Tag should never be interpreted with the same rule.
| Marking | Typical role | Public date value |
|---|---|---|
| Two numeric rows on a leather tab | Style/model above; supplier or batch reference below | None |
| One numeric row | Compact identification format on some pieces | None |
| Black fabric data tag | Letter plus digits including a three-digit group | Compiled year indication |
| Gucci Authenticity Tag | NFC feature on selected current products | Use Gucci's supported digital experience |
