I recently purchased some new AdP products and I was curious if I received the new or old formula. So I did some research and found out ways to better determine which product you have (or getting ready to buy). Since no single websites listed the codes, I used www.upcindex.com to manually search for each item, then Google search the UPC to verify.

Collezione Barbiere Shaving Soft Cream Jar has been reformulated
Collezione Barbiere After Shave Balm has been reformulated

Besides the codes, here's a few other ways to determine old vs new.
Old formula says Colonia under Acqua Di Parma, on the package and bottle/jar.
New formula does not say Colonia on it.
Old formula has a light reflective shiny lid/cap.
New Formula has a dark brown lid/cap.
Codes are located on the bottom of the package, not the product.
