Chanel started using serial numbers in their bags in the 1980’s. The numbers represent the year of manufacturing and bag style.
The serial number should match the number on the Chanel authenticity card. If it doesn’t, it’s a red flag.
If you are not buying directly from Chanel or an authorized dealer like Neiman Marcus of Saks 5th Ave, do not be satisfied with just hologram sticker and an authenticity card. Fake bags can come with hologram stickers and authenticity cards now.
Serial numbers run between six and eight digits long, depending on date of manufacturing.
Genuine Chanel clasp will have flat edges, not rounded ones. The “C” on the right will always be on top of the “C” on the left and at the bottom, the opposite is true…the “C” on the left will be on top.
Bags with the clasp provide another opportunity to check for a fake. Look at the quality and type of the screws used. The back plate that attaches the lock to the flap will screwed on with either flathead screws or star screws. Star screws have been used since 2015. Chanel does not use Phillips screws, ever.
Chanel uses Lampo metal zippers for the past two decades. Look for the Lampo logo on the back side of the zipper slider. It can say “Lampo” Or “L”.
The gold chain on Chanel bags should stand the test of time. If it is tarnished, peeling, or scratched badly, its likely not an authentic Chanel bag. Knock off Chanel bags fail very quickly. Additionally, usually if someone is paying thousands of dollars for a handbag, they take pretty good care of it, so if its abused, it’s probably not genuine.
