I have a barcode,
(9)8430709157279, that I have tried to find in several online resources that collects EAN codes but so far without luck (the product is at least 20 years old so it is no surprise). However, is it possible to find out which company or similar this code was assigned to in the beginning?
In other words, does a company get something like
84307091xxxxx and can use the "wildcards" however they like similar to IP-address ranges and MAC addresses ranges work? If so, can you lookup the prefix somewhere?
