How to Authenticate a Louis Vuitton Bag
Authenticate a Louis Vuitton bag by checking whether its model, materials, construction, markings, hardware, and date-code era agree with one another. A date code, receipt, box, or single logo detail cannot establish authenticity by itself. Use same-model, same-era references and clear close-up photos.

Louis Vuitton Date Codes: Formats, Meaning, and Limits
A Louis Vuitton date code is a production reference, not a unique serial number. Early codes used numbers for year and month; 1990–2006 codes commonly used two factory characters plus four month/year digits; 2007–early 2021 codes used the same shape but encoded week/year. Visible codes were phased out around 2021.

Why a Valid Louis Vuitton Date Code Does Not Prove Authenticity
A valid-looking Louis Vuitton date code proves only that the characters can be interpreted under a known format. The code is not unique, is not checked against a public official database, and can be copied onto a counterfeit item. Authenticity depends on the complete item and its era.

How to Authenticate a Gucci Bag
Authenticate a Gucci bag by comparing the exact model and production era across its shape, materials, monogram or logo, interior tag, number format, hardware, stitching, and construction. Serial numbers and NFC tags provide context, but neither replaces a complete item-level review.

Gucci Serial Numbers: Meaning and Limitations
A Gucci bag's so-called serial number is generally a model/style reference plus a supplier or batch reference, not a unique identity number. Modern examples often use numeric rows on the back of an interior leather tag, but formats vary by era and product. Gucci does not offer a public serial lookup that proves authenticity.

Gucci Authenticity Tag, NFC, and QR Codes Explained
Gucci's official Authenticity Tag uses NFC and is available only on selected products. Gucci instructs users to open the Gucci app, enter the Gucci Tag section, and place a compatible phone near the item. An ordinary QR label, interior serial reference, or generic NFC scan is not the same feature.
