There are also committees that regulate barcode structure and label format, the first 5 ? 6 digits signify the registered manufacturer, shipper, or regulatory organization that associated to the product.

Comittees like EAN.UCC (European Article Numbering, Uniform Code Council) you mean?

In EAN-13:
