Define SORT. NR. line on Underhood White Data sticker

[wiebeltj]

Hi 911 Technical Forum, Sure hope you can help to define the SORT. NR. first line on the Underhood White Data Sticker. This is for a 1984 Porsche 911. The COA shows all the other data on this sticker. Does any one know how I can get this exact data for my 911? Does anyone know what each original number means that should be on this line?
