  • Those numbers are production codes, in the form DWWFY, with D=day of the week, WW= 2 digit week number, F=single letter representing the factory, Y=single digit year code (6=2016). This production code allows you to determine when and where a set was made, but does not give you any information about WHAT set it is. – Phil B. Feb 18 at 16:33
