Question on Reading shoe tag / barcode labels

[Mario Mario]

Does anyone know what the number on the bottom left of a shoe tag represents?

I got a pair from stockx that had a smugdy barcode and different manufacturing date from a legit pair I got at the Niketown in Chicago. I'm just curious if that pair from stockx could have been counterfeit or just from a different batch/lot.

Either way it was missing a part and stockx honored their policy on complete shoes and took it back. Just trying to learn more for the future.

Different runs hence the different end dates.

Different runs hence the different end dates.

That makes sense. Thank you

Have you ever seen one that have straight 9’s for that bottom left number ? Shoe look very legit but I have never seen that number all 9s on any pairs of Jordan’s I have
