Five checks do most of the work when you want to know if a Louis Vuitton is authentic: the canvas layout, the made-in stamp, the date code, the hardware and the stitching. Louis Vuitton is among the most counterfeited brands in the world, so bag lovers need to protect themselves.
Check 1: the canvas and the pattern
Louis Vuitton bags are made from one piece of canvas. The logos on the front face upright, while the logos on the back are upside down, which means there is no separation at the base of the bag. If the logo is hidden or cut off anywhere, it is likely a knockoff, because the LV logo is rarely cut off on an authentic piece. The pattern should always be straight, never at an angle or crooked.
Check 2: the made-in stamp
The made-in stamp is a clear indication of authenticity. It always reads "Louis Vuitton" with "made in France" underneath, though it can name another country if the bag was made elsewhere. The tell is in the lettering: a short leg at the bottom of the Ls, O's that are bigger than the L and perfectly round, T's that sit close together and appear to touch, and letters that stay thin and crisp.

Check 3: the date code
Date codes matter enormously, because they tell you the month and year a bag was produced. Bags made before 1980 do not have one. The codes use letters to indicate the region, with combinations like MI, SD, TH and VI marking French production, followed by numbers. The classic format is two letters and four numbers, stamped on the top edge of the bag's opening.
Check 4 and 5: hardware, stitching and lining
The hardware should be real metal with a gold coating, with no discolouration or tarnish, and the printing on it should be precise. LV logos appear on snaps if the bag has them, and vintage handles develop a patina over time. For stitching, look for five mustard-yellow stitches across the top of each handle, all neat and even. The interior lining of most Louis Vuitton bags is a brown canvas, though some designs use cross-grain leather, polyester or microfibre suede.
What does professional authentication add?
Technology is key in determining authenticity. Modern authentication inspects hardware, serial numbers, stamping, logo and printing, and once a bag is deemed authentic it receives a financially guaranteed certificate. That level of documentation is why buying from authenticated sellers beats gambling on a stranger's photos.
Frequently asked questions
Where is the date code on a Louis Vuitton bag?
On the top edge of the bag's opening. The classic format is two letters and four numbers, and bags made before 1980 do not carry a date code at all.
What should the made-in stamp look like?
It should read Louis Vuitton with made in France beneath it, or another country of origin. Look for thin, crisp letters, round O's and T's that sit close together.
How many stitches should Louis Vuitton handles have?
Five mustard-yellow stitches across the top of each handle, stitched evenly and neatly. Uneven or wandering stitch lines are a hard fail on any authentic piece.
