条码系统有两种:美国用UPC编码,在这个系统中不包括起源国家。另一个是EAN-13系统,欧洲和许多其它地区使用,是有起源国信息的。但是所谓起源国是设计和组织生产的国家,并不是真正的生产地。
这是下面两段英文的大意,作者揭露了网上流传的说法是误导。
There's more than one kind of bar code in use around the world. UPC
bar codes, the type most commonly used in the United States, do not
typically contain a country identifier. A different type of bar code
known as EAN-13 does contain a country identifier, but it's more
commonly used in Europe and other countries outside the U.S.
Even in the case of EAN-13 bar codes, the digits associated
with country of origin don't necessarily specify where the product was
manufactured, but rather where the bar code itself was registered. So,
for example, a product manufactured in China and sold in France could have an EAN-13 bar code identifying it as a "French" product.

000~019 ,030~039,060~139 都是美国在使用;
020~029,040~049,200~299 店内码[美国];
050~059 优惠券[美国]
450~459,490~499 是日本在使用
690--695 都是中国国内使用 ,所以你在超市看到的绝大部分条码都是
690--695打头的。
