What are those numbers on the bar code of a Bandai figure tag / box?
The serial numbers, also known as stock numbers, of a Bandai figure are unique to each toy, thus can be used in order to be sure of getting a correct tag with a figure, which could otherwise be a problem for those earlier figures whose tags bear no distinguishing characteristics not in Japanese. The serial number is located on the tag of the figure, above the barcode. The earliest figures, instead of a serial number, had a Collection Number. The serial numbers are, for the most part, a series of three strings of numbers separated by dashes. The first string, 205020, is carried by all Bandai Godzilla figures (as well as other Bandai series figures) with a serial number; the second, and most important, is individual to each figure. The third string denotes the original price of the vinyl toy in Yen.
