LV Date Code Calculator
Your expert tool for decoding Louis Vuitton factory and date information.
What is an LV Date Code?
A Louis Vuitton date code is a small stamp found inside LV items that indicates where and when the item was made. It is not a serial number and is not unique to the item. Instead, it’s a manufacturing code used internally. For collectors and enthusiasts, the lv date code calculator is an essential tool for verifying an item’s history. These codes consist of letters and numbers that, when deciphered, reveal the country of production and the specific week or month and year of creation. Understanding these codes is crucial because an incorrect or mismatched date code is a major red flag for a counterfeit product. Since March 2021, Louis Vuitton has transitioned to embedding microchips, phasing out the physical date codes on new products.
LV Date Code Formula and Explanation
The “formula” for reading an LV date code has evolved over the decades. The calculator above handles these conversions automatically, but understanding the logic provides deeper insight. The format typically involves two letters for the factory location and four numbers for the date.
| Period | Format | Explanation | Example |
|---|---|---|---|
| Pre-1982 | None | Items made before 1982 did not have date codes. | N/A |
| Early 1980s | 3 or 4 Numbers | First two numbers are the year, last one/two are the month. | 836 = June 1983 |
| Late 1980s | 3/4 Numbers + 2 Letters | Year/Month numbers followed by a two-letter factory code. The letters can also appear before the numbers. | 874VX = April 1987, France |
| 1990 – 2006 | 2 Letters + 4 Numbers | Two-letter factory code, then 1st & 3rd numbers are the month, 2nd & 4th are the year. | VI1025 = December 2005 |
| 2007 – Feb 2021 | 2 Letters + 4 Numbers | Two-letter factory code, then 1st & 3rd numbers are the week, 2nd & 4th are the year. | SD2057 = 25th week of 2007 |
| Mar 2021 – Present | Microchip | Date codes were replaced by RFID microchips embedded in the item, scannable at LV stores. | N/A |
Timeline of LV Date Code Formats
Practical Examples
Example 1: Post-2007 Bag
- Input Code: FL4158
- Analysis: The factory code is ‘FL’, which can be France or the USA. The numbers are 4158. Following the 2007-2021 format, the week is the 1st and 3rd digits (45th week), and the year is the 2nd and 4th digits (2018).
- Result: Manufactured in the 45th week of 2018 in France or the USA.
Example 2: Pre-2007 Bag
- Input Code: SP0994
- Analysis: The factory code is ‘SP’ for France. The numbers are 0994. Following the 1990-2006 format, the month is the 1st and 3rd digits (09, September), and the year is the 2nd and 4th digits (94, so 1994).
- Result: Manufactured in September 1994 in France.
How to Use This LV Date Code Calculator
Using the lv date code calculator is a straightforward process designed to give you quick and accurate results. Here’s a step-by-step guide:
- Locate the Date Code: First, you need to find the date code inside your Louis Vuitton item. It’s often on a small leather tab inside a pocket, stamped on the lining, or near a seam. Check out our guide on how to find a date code for more tips.
- Enter the Code: Type the code exactly as it appears into the input field at the top of this page. The calculator is not case-sensitive.
- Interpret the Results: The calculator will instantly process the code. The primary result shows the manufacturing location and date. The intermediate results break down the code into its components (factory code, year, month/week).
- Check the Formula: An explanation is provided below the results, detailing which date code format was detected and how the date was calculated. This helps you understand the logic behind the output.
Key Factors That Affect an LV Date Code
Several factors can affect the presence, legibility, and interpretation of a date code.
- Age and Wear: On older bags, especially those with an Alcantara microsuede lining, the heat-stamped date code can fade and become completely illegible.
- Item Type: The location of the date code varies significantly between different types of items like handbags, wallets, and luggage.
- Repairs: If an item has been officially repaired by Louis Vuitton, the lining may have been replaced, sometimes with a new date code tag that represents the repair date, not the original production date. These sometimes use the ‘DK’ code.
- Counterfeits: This is the most critical factor. Counterfeiters often use fake but plausible-looking date codes. A valid date code does not guarantee authenticity. It must match the “Made in…” stamp and other features of the bag. Learn more about authenticating LV bags.
- Production variations: Sometimes, date codes can be mis-stamped or look slightly different. This is rare but possible.
- The Microchip Transition: Items produced after March 2021 will not have a date code at all, which can confuse those unaware of the new RFID technology.

Frequently Asked Questions (FAQ)
Does a valid date code guarantee my bag is authentic?
No. This is a common misconception. A valid date code is just one piece of the puzzle. Many counterfeit items have date codes that appear correct. You must also check the “Made in…” stamp, material quality, hardware, and stitching. Using an LV authentication service is recommended for definitive verification.
Why can’t I find a date code in my new Louis Vuitton bag?
Louis Vuitton stopped using date codes in March 2021. New items now have an embedded RFID microchip that is not visible. This chip contains information about the item and can only be scanned by Louis Vuitton staff.
What if my bag’s date code is faded or unreadable?
This is common in older bags, especially those with soft Alcantara linings. The heat stamp can wear away over time. While our lv date code calculator can’t help with a missing code, the absence of a legible code doesn’t automatically mean the bag is fake, especially if it’s a well-used vintage piece.
The calculator says “France or USA”. Why isn’t it specific?
Some factory codes, like ‘FL’ and ‘SD’, have been used in factories in both France and the USA at different times. The date code itself does not distinguish between them. You must cross-reference with the “Made in…” stamp on the bag to determine the correct country of origin.
What does it mean if the date code country doesn’t match the ‘Made In’ stamp?
If the date code indicates ‘Made in Spain’ (e.g., a ‘CA’ code) but the bag is stamped ‘Made in France’, it is a very strong indicator that the item is a counterfeit. This is a common mistake made by forgers.
Is this lv date code calculator free to use?
Yes, this calculator is completely free. It is designed as a resource for enthusiasts and collectors to quickly check the production details of their items.
Can this calculator spot a fake bag?
The calculator can only spot invalid or nonsensical date codes. It cannot determine if a bag is a counterfeit. A well-made fake can have a perfectly valid date code. Always use a professional authentication service for a final verdict.
Where is the date code on a Speedy or Neverfull?
On most Speedy and Neverfull bags, the date code is stamped on a leather tab located under the interior slip pocket. You may need to lift the pocket up to see it clearly.
