Just where did that mango come from and what was the path?

"The code's basic four digits simply signify a produce variety and size category. A "9" preceding the four-number string indicates the produce is organically grown and an "8" indicates that the produce is genetically modified.

PLU codes are easily searched through a publicly available database maintained by the International Federation of Produce Standards. When I looked up my mango's PLU—94959—I learned that it was an organic large red mango (other size categories are small and extra large) of the Tommy Atkins, Kent, Palmer, Vandyke, Edward and Hayden varieties. A PLU code isn't intended to tell you anything else, including where the produce comes from."
