Codes starting with 2,4 for UPC, 02,04 (UPC compatible) for EAN / JAN, and 20-29 are available. The code starting with UPC 2 (02 as JAN code in Japan) is a NON-PLU (non-price lookup) that has the price in the code without referring to it from the database, and is especially used for weighing products. Codes starting with 4 (04) can use 10 digits, and codes starting with 20 to 29 can use 2 digits after 11. 20 to 29 are used for the membership number of the store's own membership card.
