If it's embossed on the back with 'Made in France' then it's made in France
The code, if you look carefully, is on the reverse side of the leather flap.

hi CHLongchamp, I have the same situation as MicheleAudrey above.
I bought a Longchamp Le Pliage online and I believe that it is an older version for the reason that there is still that line under the longchamp logo on the leather flap which was their old logo as I read here on older threads. I love vintage Le Pliage and as I inspected all the specifications that would indicate if it's the real thing, all checked out - except for one.
This bag doesn't have the plastic inner label/tag inside where you see where it's made from and the codes (usually sewn on the inner side of the bag). It didn't also have an inner leather label saying 'Made in France' which I see in some older Limited Editions.
Did Longchamp ever make Le Pliage before without this "Made in" plastic inner labels or even those leather "Made in France" labels inside? It does however have the embossed wordings at the back leather portion saying "Longchamp Paris" (on the first line) and "Modele Depose - Made in France" (on the second line). I also noticed that the embossed jockey logo in the front leather flap is not quite seen on the reverse side (the newer authentic ones have embossed markings of the logo on its reverse leather flap side). Please share what you think of it? I'm worried. TIA!
