Unlock the Mystery of Your YSL Bag’s Manufacturing Date
How to Know When Your Saint Laurent Bag Was Made: Crack the Secret of YSL Date Codes
Every Saint Laurent (YSL) bag has a hidden date code – think of it like the bag’s ID card. This code is a mix of letters and numbers that tells you when and where the bag was made, helping prove its authenticity. Fashion lovers and collectors use these codes to unlock a bag’s production date. Once you know where to look and how to read it, you’ll see the story your bag’s serial number is telling you.
Where to Find the Serial Number
The first step is to find where it is. Here’s where to look:
Leather Tag: Most YSL bags have a small rectangular leather tag sewn into the lining, usually near the zipper or inside an interior pocket. The tag often matches the bag’s color, so it blends in. The serial number is typically embossed or printed on this tag.
Heat-stamped: In newer YSL models, the serial number might be heat-stamped directly onto the interior lining, often inside a pocket or near the seam. This is common for bags from recent collections.
Tip: If you’re struggling to find it, use a flashlight to check pockets or seams carefully. The number might be subtle, but it’s there!
Understanding the Serial Number Format
YSL bags use different serial number formats depending on whether they’re vintage or from newer collections. Here’s a breakdown:
Vintage Bags: These have a straightforward 12-digit number split by a single dot, like 123456.789012.
Newer Bags: These start with three letters followed by six digits a dot, and then four digits at the end. For example: ABC123456.7890
Note: Real YSL code is always in a single line with uniform font and spacing. If you see a multi-line or sloppy print, that’s often a sign of a fake.
Decoding the Date Code
Now, let’s get to the most exciting part: the date code itself, which tells you when your bag was made. For newer YSL bags, decoding the code is easy. In this example PMR657228.0422, here’s how to read it:
First Tree Letters: PMR identifies the workshop or factory.
Next 6 Digits: 657228 is the style number, which you can sometimes verify on the YSL official website.
Last Four Digits: 0422 is the date code; the first two digits represent the month of production. 04 means April. The last two digits indicate the production year. 22 means 2022
In short, break the code into parts and apply MMYY (M=Month; Y=Year) to the final four digits. For example, a code ending in 1219 would mean December 2019.
Why Knowing the Date Code Matters
Knowing the date code isn’t just trivia – it’s a smart way to confirm authenticity and value. Date codes give buyers and sellers confidence by verifying when and where a bag was made. Real YSL codes always follow the rules: they are stamped in one line with a uniform font and usually have “MADE IN ITALY” or similar printed below. If a code is misaligned, in multiple lines, or uses a strange font, be cautious.
However, the date code is just one piece of the authentication puzzle. To truly confirm a YSL bag’s authenticity, you need to examine other elements like the logo, hardware, stitching, lining, and materials.
