Understanding UCC Identification Codes

Each company can assign product identification codes. The UCC, the ECCC, and the EAN (outside of Canada and the United States) assign member companies the company identification. In the company identification codes, the first digit is the region code. For North America, the region code is 0. Therefore, the company identification can be seven digits if the first digit as zero. Because each UCC code contains the company number, all numbers are unique.
