Universal Product Code.
The UPC standard version consists of 12-digits; 1 digit of NS code, 5 digits of maker code, 5 digits of item code and 1 digit for checkdigit code. In America and Canada, the UPC 12-digit based systems are rather than the 13-digit EAN symbol. Therefore, imported products into the U.S. and Canada must display UPC symbols. By 2005, scanners are to be able to scan both UPC and EAN symbols in the U.S. and Canada.CreativeMinds WordPress Plugin Super Tooltip Glossary
