Comparison of UPC, EAN and GTIN[edit]

The "Universal Product Code, UPC, has been a dominant barcode standard in "North America since it was established in the 1970s. It encodes a 12 digit number (GTIN-12), unique to a product, which allows it to be scanned and read in virtually any major retail establishment. A 6 digit "zero-suppressed" version (UPC-E) is available for items which are too small to allow the larger UPC-A version to be printed.

The EAN-13 and EAN-8 are other point of sale barcodes that are widely used outside of North America. A UPC formed in the United States can be transformed into an EAN by prefixing it with a zero.

The Global Trade Item Number, GTIN, is an identification number that may be encoded in UPC-A, UPC-E, EAN-8, and EAN-13 barcodes as well as other barcodes in the GS1 System.
