Where to find serial number on MATELASSE WOC

[DimpleGirl]

Hi - I was wondering where I can find the serial number for a Matelasse wallet on chain? I purchased the bag at a YSL boutique so I'm sure it's authentic but I'm not able to find the serial number on the bag. This is the bigger size (20 card slots). Thanks.

I found mine! At the back of the credit card pocket. But mine is the smaller one and it's the envelope chain wallet. I read somewhere that woc's serial number is at the back leather of the zipper in the middle. Very hard to find.
