Okay, guys, so I’ve been getting a ton of questions lately about how to tell if a Louis Vuitton bag is the real deal or a fake. I totally get it – nobody wants to drop serious cash on a designer bag only to find out it’s a knockoff. So, I decided to do a little experiment and share my process for checking the authenticity of a Louis Vuitton using the serial number.

First off, I grabbed my favorite LV bag, the one I bought a few years back from the boutique. I figured it was a good starting point since I knew for sure it was authentic. Now, every real Louis Vuitton has this thing called a “date code” – it’s like a secret code that tells you where and when the bag was made.
Finding the Date Code:
- Look Inside: I started by digging around inside the bag. The date code isn’t just sitting out in the open; you gotta hunt for it. Usually, it’s tucked away on a little leather tab or stamped directly onto the lining, especially in the pockets.
- Check Pockets: In my bag, I found it hiding inside one of the interior pockets. It was stamped onto a small, rectangular piece of leather that was stitched into the lining. It took a bit of rummaging, but I found it!
Decoding the Date Code:
- Format: My bag’s date code was two letters followed by four numbers. From what I’ve learned, the letters indicate the country where the bag was made (mine was “SP,” which means France), and the numbers tell you the month and year of production.
- Break It Down: In my case, “SP0605” meant it was made in France (SP) in the sixth month (06) of 2005 (05). Pretty cool, huh?
Comparing with a Suspect Bag:
Next, I got my hands on another LV bag that I suspected might be fake. I went through the same steps to find its date code.

- Locate the Code: I found a code, but it was in a weird spot, not consistent with where authentic bags usually have them. Strike one.
- Decode and Verify: The code itself didn’t make sense. The format was off, and the letters didn’t match any known Louis Vuitton factory locations. Plus, the year didn’t align with the style of the bag. Strike two and three!
My Findings:
So, after this little experiment, it became pretty clear that knowing how to find and interpret the date code is super important for spotting a fake Louis Vuitton. The real bag had a date code that was properly formatted and located in the right spot. The fake one? Not so much. The code was all messed up and in a totally off location.
Remember, guys, this is just one part of authenticating a Louis Vuitton. There are other things to look for, like the quality of the stitching, the hardware, and the overall craftsmanship. But checking the date code is a great first step. Hope this helps you out on your next designer bag hunt!
