It does, but the only real requirement is to prevent duplicates. It's not a limited resource like domains or IP4 addresses. There's no justification for the subscription model aside from "because we can". They used to give out numbers in perpetuity, but eventually realized there was a lot more money to be made. Dividing blocks over multiple competing providers is a good suggestion. |

Interestingly, it doesn’t look like IKEA uses UPC barcodes at all and just has their own format and numbers. I guess since they only sell their products in their own stores, there is no need for it to be globally unique.
