The bar code identifies the specific type of product, not a n individual example within that type of product. It’s not a serial code.
I ran into this a lot when I worked for a pet food manufacturer. If there was an issue with a product, customers often assumed the UPC could identify when the product was made, where it was distributed, and even where it was purchased. It does not. Otherwise packaging would be incredibly inefficient to make because each bag of the same recipe and size would need its own unique UPC.
