The website provides information about the GTIN (Global Trade Item Number) and its definition. It explains that a GTIN is a family of EAN/UCC global data structures encoded into various types of data carriers, such as barcodes and RFID tags. The primary use of GTINs is within barcodes, but they can also be used in other forms of data carriers. The website further mentions the different types of numbering strings included in the GTIN family, such as GTIN-12 (UPC-A), which is primarily used in North America; GTIN-8 (EAN/UCC-8), predominantly used outside North America; and GTIN-13 (EAN/UCC-13), also mainly used outside North America.
