Louis Vuitton
Louis Vuitton is among the most faked brands in the world, and counterfeiters routinely copy valid-format date codes — so a date code alone proves nothing. Check the code against the "Made in" stamp, the heat stamp, and the stitching together.
Date Codes & RFID
Date codes encode the factory and production date — but the format changed several times, and since March 2021 LV uses scannable RFID chips instead of stamped codes.
LV did not use date codes before 1982 — their absence on genuine vintage pieces is normal.
Critical Red Flags
- Date-code country doesn't match the "Made in" stamp (e.g. an Italy code on a "Made in France" bag).
- Seller provides an "authenticity card" — LV has never included authenticity cards with handbags.
- A stamped date code on any bag made after March 2021 (those use RFID chips only).
- Treating a valid-format date code as proof — counterfeiters replicate them constantly.
The date-code trap
A legitimate-looking date code does NOT guarantee authenticity. Authentication services regularly find fakes carrying valid-format codes — always corroborate with the heat stamp, stitching, hardware, and materials.
Heat Stamp
- Lettering is thin and sharp; the "L" has a short horizontal base and the "O"s are round.
- The two "T"s in VUITTON touch or sit very close together.
- The ® symbol typically sits between the "N" of VUITTON and "PARIS".
- Stamp is evenly pressed and perfectly aligned — never crooked or smudged.
Stitching & Materials
Thread
✓ AUTHENTIC
Waxed linen thread in a subtle mustard-yellow tone.
✗ COUNTERFEIT
Synthetic thread in a bright yellow or orange.
Stitch consistency
✓ AUTHENTIC
Even spacing and identical angle throughout; symmetrical elements have matching stitch counts.
✗ COUNTERFEIT
Uneven spacing, inconsistent angles, loose threads.
Where to buy safely
Buy from Louis Vuitton directly or resellers that authenticate (Fashionphile, The RealReal, Rebag). Be wary of stock photos, prices well below retail, and pressure to pay fast.
Get Professional Authentication
Visual checks catch obvious fakes, but professional authentication is the only way to be certain — especially for high-value purchases.
