A Louis Vuitton date code is a small set of letters and numbers, stamped or embossed inside the bag, that tells you where and roughly when the piece was made. They are one of the most useful checks when you buy pre-loved, and one of the most misunderstood. This guide shows where to find the code on different models, how to read it era by era, and what a missing or odd code really means.
Where to find the date code
On most Louis Vuitton bags the code sits on a leather tab stitched inside, usually in a seam or along the interior wall. Look:
- Inside the main compartment, along the seam (Speedy, Neverfull, Alma);
- Under an interior flap or pocket (Pochette Métis, wallets);
- On the edge of the interior lining of small leather goods, stamped directly into the material.
A flashlight and a phone camera on video make it much easier to find. It is often tiny, two lines of text, and lightly embossed.

How to read it, era by era
The format changed several times. Match the code to the era, not the other way around.
| Period | Format | Example | What it means |
|---|---|---|---|
| Before 1980 | No code | None | Older pieces simply do not have one; this is not a red flag. |
| 1980s | 3 to 4 digits | 836 | Early numeric systems, formats vary by year. |
| 1990 to 2006 | Two letters + four digits | VI 0912 | Letters: factory. Digits: month and year (September 2012 in this reading varies; read as MMYY). |
| 2007 to 2021 | Two letters + four digits | SP 1150 | Letters: factory. Digits: week and year (week 11 of 2020). |
| From 2021 | No code (chip) | None | Most bags moved to an RFID chip; date codes were discontinued. |
The trick is the 2007 switch: the same four digits describe a month in older pieces and a week in newer ones. A code like 4212 is either April 2012 or week 42 of 2012 depending on when the bag was produced.
After 2021: the chip era
From spring 2021 Louis Vuitton phased out the stamped code on most leather goods and introduced an RFID chip that boutiques scan. If a modern bag has no code, that alone tells you very little. The presence of a code is reassuring on older pieces; its absence on a 2026 Neverfull is normal.
"My bag has no date code. Is it fake?"
Not necessarily. The code is one signal among many. Judge a bag as a whole: the quality of the stitching, the evenness of the monogram alignment, the hardware weight and engraving, the smell and finish of the leather. A code can also be faked. Treat it as a hint, not a verdict, and use a professional authentication service for anything you are unsure about.
Frequently asked questions
Where is the date code on a Neverfull?
On recent pre-chip Neverfulls it sits inside, on the leather trim of the interior edge or under the pocket seam. Use a phone light; it can be faint.
Do new Louis Vuitton bags still have date codes?
Mostly no. Since 2021 most leather goods use the chip instead. A few product types kept stamps longer.
Does a date code prove authenticity?
No. Codes are matched to era and factory lists, which is a strong signal, but counterfeits copy common codes. Combine it with the piece's hardware, stitching and provenance.
