What Louis Vuitton Date Codes Actually Are
Louis Vuitton uses "date codes" — not serial numbers. The distinction matters: the date code doesn't uniquely identify an individual bag (LV doesn't use a one-bag-one-number system). Instead, it encodes the factory location and production period. Multiple bags with the same date code exist and are all potentially authentic.
The code is stamped on a leather tab inside the bag, directly on the interior lining, or inside a pocket. The exact placement varies by model and era. Starting in 2021, Louis Vuitton replaced visible date codes with internal RFID chips — so a brand-new bag with no visible code is completely normal and not a fake tell.
Understanding these codes is genuinely useful for authentication because: (a) a code in the wrong format for the claimed era is a red flag, (b) a code that contradicts the "Made in..." country label is suspicious, and (c) a code that predates a model's actual introduction is impossible.
Date Code Formats by Era
Before 1982
No codes were used. Louis Vuitton bags from the 1960s and 1970s have no date code. Authentic — a missing code on a vintage piece is expected, not suspicious.
1982 – Mid-1980s
3–4 numeric digits only. Example: 834 = 1983 (83), April (4). The format is [last two digits of year][month number]. Sometimes written as 8304 where 83 = 1983 and 04 = April.
Mid-1980s to 1989
Factory letters introduced alongside the digits. Example: VI 883 = France (VI factory), August (8) of 1983 (83). Format: [factory letters][year digits][month digit].
1990–2006
Standardized to two factory letters + four digits. The digits encode month and year in an alternating pattern: 1st and 3rd digit = month, 2nd and 4th digit = year. Example: SP1025 → S and P identify the factory (France), 1st digit 1 and 3rd digit 2 = month 12 (December), 2nd digit 0 and 4th digit 5 = year 05 = 2005. So December 2005, made in France.
2007–Early 2021
Same two letters + four digits format, but digits now encode week and year rather than month and year. 1st and 3rd digits = week of year, 2nd and 4th digits = year. Example: FL3089 → Factory FL (France), 1st digit 3 and 3rd digit 8 = week 38, 2nd digit 0 and 4th digit 9 = year 09 = 2009. So week 38 of 2009, made in France.
2021–Present
Date codes discontinued and replaced by RFID chips embedded in the bag's lining. No visible code on a new bag is normal. RFID chips can be detected with a smartphone NFC reader but the database can only be accessed by Louis Vuitton staff at a boutique.
Factory Code Reference by Country
| Country | Factory Codes |
|---|---|
| France | SP, FL, AR, DU, CT, MB, MI, NO, RI, SD, TH, TR, VI, LM, LA |
| Spain | CA, LO, UB, LB, GI, BC |
| Italy | FO, MA, RC, RE |
| USA | SD, TX, OS, FC, FH |
| Switzerland | FA, DI |
| Germany | LP |
Important: The factory code must match the "Made in [Country]" stamp inside the bag. A code starting with CA (Spain) on a bag stamped "Made in France" is contradictory and suspicious.

Check My Date Code →How to Use the Date Code in Authentication
The date code is a starting point, not a conclusion. Here's how to apply it:
Step 1 — Verify the format matches the claimed era. If someone tells you a bag is from 1998, the code should be in the two-letter + four-digit format where digits encode month/year. A week-based format on a claimed 1998 bag is wrong.
Step 2 — Check the country consistency. The factory code prefix should match the "Made in..." label. Mismatches indicate tampering or a fake.
Step 3 — Cross-reference with model history. Every LV model has a known introduction date. A Neverfull with a date code from 2003 is impossible — the Neverfull wasn't introduced until 2007. Check when the specific model was first produced.
Step 4 — Don't stop at the code. Fakes copy correct codes. After verifying the code format, continue with physical authentication: canvas texture, hardware weight, stitching quality, heat stamp depth.
Why the Same Code Can Appear on Both Authentic and Fake Bags
Counterfeiters copy real date codes from genuine bags. This is common. A "correct" code tells you the format is right — it doesn't prove the bag is genuine. Physical authentication markers are always required alongside code verification.
This is also why a code that looks "too perfect" — printed too neatly, too clearly, or too boldly compared to the surrounding leather — can itself be a red flag. Authentic codes are fine and subtle; fakes sometimes over-engrave them to make them more visible and "convincing."
Common Code Decoding Mistakes
Month/Week confusion: People frequently misread 1990–2006 codes using the week-based formula (post-2007). The decoding method changed — applying the wrong formula produces an incorrect date and creates false suspicion about authentic bags.
Dismissing early codes: Bags from the early 1980s sometimes have codes that produce no result in online databases. This doesn't mean they're fake — early numeric-only codes are poorly documented in digital tools.
Assuming French manufacture is more "authentic": LV produces in France, Spain, the USA, Germany, and Switzerland. All are authentic. A Spanish-made bag is not less genuine than a French one.
Authentication Checklist
- Code present (or absent on post-2021 bags — both are normal)
- Format matches the correct era for the bag's claimed age
- Factory letter prefix matches the "Made in..." country label
- Code date doesn't predate the model's known introduction date
- Code appearance — fine and subtle, not over-engraved
- Physical markers (canvas, hardware, stitching) also pass inspection
FAQ
What does it mean if there's no date code on a pre-2021 bag?
A missing code on a post-1982 bag that should have one is a red flag but not automatic proof of a fake. Codes can wear off on very old bags, be placed in an unusual location, or — in rare cases — be absent due to a production anomaly. If the code is missing, evaluate all physical markers more carefully and consider professional authentication.
Can I check a Louis Vuitton date code myself?
Yes. Our Louis Vuitton date code tool decodes all formats from 1982 to 2021, identifies the factory country, and shows the production year or week. For very early 1982–1989 numeric codes, the tool notes the limited documentation available for those formats.
Do LV bags made in Spain have lower quality than French ones?
No. Louis Vuitton maintains the same quality standards across all production locations. The choice of where to produce a particular model is a logistical decision, not a quality decision. Spanish-made LV bags are fully authentic and consistent with the brand's standards.
Does a date code from 2015 mean the bag was brand new in 2015?
It means it was produced in that period — but production date and sale date can differ. LV produces bags in advance of demand, so a 2015 production code doesn't mean the bag was sold in 2015. It could have sat in inventory or been purchased later.
What should I do if the date code format doesn't match any era?
Cross-reference it again — month/week decoding confusion is the most common error. If after correcting for era the format is genuinely wrong, that's a significant authentication concern. Have the bag examined by a professional who can look at physical markers alongside the code.
