Louis Vuitton Date Code Checker
Decode the production date and likely country association expressed by a Louis Vuitton date code. The result checks the code's structure; it does not authenticate the item.
- Interprets month/year and week/year eras separately
- Labels factory locations as common associations, not certainty
- Rejects impossible month and week values
Important
A plausible date code does not prove authenticity. Counterfeit items can copy valid-looking codes, and factory-code references can vary. Verify the complete item before buying or selling.
Direct answer
What a Louis Vuitton date code can and cannot tell you
It can provide production context
Depending on the era, the code can express a month or week, a two-digit year, and a facility code commonly associated with one or more countries. That information is useful when you compare the date with the model, materials, and country stamp.
It cannot prove authenticity
Date codes are not unique serial numbers and counterfeit items can repeat valid-looking formats. A complete review also considers construction, canvas or leather, typography, hardware, stitching, model details, and legitimate era variation.
Read why code validity is limitedDate-code formats by era
| Era | Common format | Interpretation |
|---|---|---|
| Before the early 1980s | Usually no date code | The absence of a code can be consistent with an older item. It is not an authenticity result. |
| Early 1980s | 3 or 4 digits | The first two digits commonly indicate the year and the remaining digit or digits indicate the month. |
| Mid-to-late 1980s | 3 or 4 digits, then 2 characters | The date appears first. The final characters commonly identify a production facility. |
| 1990-2006 | 2 characters, then 4 digits | The first and third digits indicate the month; the second and fourth indicate the year. |
| 2007-early 2021 | 2 characters, then 4 digits | The first and third digits indicate the production week; the second and fourth indicate the year. |
| Around 2021 onward | No standard visible date code | Louis Vuitton phased visible codes out in favor of embedded chips. No visible code can be normal for a newer item. |
Format transitions were not perfectly uniform across every product and facility. Worn or repaired items can also have faint, inaccessible, or replaced interior components.
