Louis Vuitton date codes can reveal when and, in many cases, where an item was made. They are not serial numbers and they do not prove authenticity on their own. The format changed several times before visible date codes were replaced by embedded chips in newer pieces.
What Is a Louis Vuitton Date Code?
A Louis Vuitton date code is a short sequence of numbers, or letters and numbers, used on many bags and small leather goods from the early 1980s until early 2021. Depending on the production period, the code identifies a month or week of manufacture and may also indicate a workshop location.
A date code is different from a unique serial number. More than one item can carry the same code because several pieces may have been produced at the same workshop during the same period. This is why a code should be treated as production information rather than an individual identity number.
Louis Vuitton Date Code Timeline
The quickest way to decode a Louis Vuitton date code is to identify the era first. The arrangement of the letters and numbers determines which reading method applies.
| Production period | Typical format | How to read it |
|---|---|---|
| Before the early 1980s | Usually no date code | Absence of a code can be normal for older vintage pieces |
| Early 1980s | Three or four numbers | First two numbers usually show the year, remaining numbers show the month |
| Mid to late 1980s | Three or four numbers followed by two letters | Numbers show the date, letters identify the workshop |
| 1990 to 2006 | Two letters followed by four numbers | First and third numbers show the month, second and fourth show the year |
| 2007 to early 2021 | Two letters followed by four numbers | First and third numbers show the week, second and fourth show the year |
| From 2021 | Embedded chip | Many newer pieces no longer carry a visible traditional date code |
How to Read Louis Vuitton Date Codes
Early 1980s Codes
Early codes generally contain three or four numbers. The first two digits indicate the year and the final one or two digits indicate the month. For example, 836 is commonly read as June 1983. These early systems were less consistent than later formats, so vintage examples should always be assessed in context.
Codes From 1990 to 2006
During this period, Louis Vuitton generally used two workshop letters followed by four numbers. Read the first and third numbers together to find the month. Read the second and fourth numbers together to find the year.
For example, SP0995 becomes 09 for the month and 95 for the year. It therefore indicates production in September 1995. The letters SP are associated with production in France.
Codes From 2007 to Early 2021
The appearance remained similar, but the date logic changed from month and year to week and year. The first and third numbers form the production week, while the second and fourth form the year.
For example, CA1088 becomes week 18 of 2008. CA is commonly associated with production in Spain. A week number should normally fall between 01 and 53.
Quick Decoding Examples
| Example | System | Meaning |
|---|---|---|
| 836 | Early 1980s | June 1983 |
| SP0995 | 1990 to 2006 | SP workshop, September 1995 |
| VI1025 | 1990 to 2006 | VI workshop, December 2005 |
| CA1088 | 2007 to 2021 | CA workshop, week 18 of 2008 |
| TR3117 | 2007 to 2021 | TR workshop, week 31 of 2017 |
Common Factory Codes by Country
The two letters usually identify a manufacturing workshop rather than acting as a simple permanent country abbreviation. Some codes were used in more than one country or during different periods, so the code should agree with the country stamp and the age of the item.
| Country | Common examples |
|---|---|
| France | AR, DU, MB, SP, TH, TR, VI |
| Spain | CA, GI, LB, LM, LO, UB |
| Italy | BC, BO, CE, FO, MA, PL |
| United States | FC, FH, LA, OS, SD, TX |
| Germany | LP, OL |
| Switzerland | DI, FA |
This is a practical reference rather than an exhaustive list. Factory code records vary between specialist sources, and shared codes such as SD require the production date and country marking to be considered together.
Where to Find a Louis Vuitton Date Code
Date code placement depends on the model, size, lining, and production year. Use good natural light and check carefully rather than pulling hard on a leather tab or lining.
- Inside an interior pocket, often close to the top edge or side seam
- On a small leather tab sewn into the lining
- Stamped directly onto leather, textile, or suede like lining
- Behind a card slot or inside a compartment on wallets and small leather goods
A faint or missing stamp does not automatically indicate a counterfeit. Heat stamps can fade through age, friction, cleaning, or wear, particularly on soft linings.
Why Newer Louis Vuitton Bags May Have No Date Code
Louis Vuitton moved away from traditional visible date codes around early 2021 and introduced embedded identification chips. These chips are intended for internal product information and are not designed as public tracking devices. A customer usually cannot decode the information with an ordinary phone application.
Consequently, a recently produced LV bag without a visible date code is not automatically suspicious. Its expected production period, materials, construction, and purchase history are more useful than searching indefinitely for a stamp that may never have been applied.
Can a Date Code Prove Authenticity?
No. Counterfeiters can copy genuine looking date codes, including codes that follow the correct numerical pattern. A believable code only tells you that the stamp is plausible. It does not establish that the materials, pattern alignment, stitching, hardware, typography, and construction are correct.
Look for internal consistency. The format should match the claimed production era, the workshop code should make sense beside the country marking, and the decoded date should fall within the period when that model or edition was produced. Any conflict deserves closer examination by an experienced authentication service.
Common Date Code Mistakes
- Reading a code made after 2007 as a month and year code instead of a week and year code
- Assuming every authentic vintage bag must have a visible code
- Treating the workshop letters as permanent country abbreviations
- Using a valid looking code as the only proof of authenticity
- Ignoring whether the date is realistic for the specific model and materials
Conclusion
Louis Vuitton date codes are most useful as a window into an item’s production history. Once you identify the correct era, the numbers can reveal a month or week and a year, while the letters usually point towards a workshop. Use the information as one part of a careful assessment, not as a guarantee that a bag is genuine.
