UPC and EAN are types of product numbers also referred to as GTIN (Global Trade Identification Numbers).
UPC and EAN barcode numbers can be used in keyword searches to find exact matching items for specific products. This is an alternative to using keywords that sellers may or may not include in their item titles or descriptions.
To use UPC or EAN codes in BINSniper and VieBuy.com, simply include them in the keyword field of your filters. To search multiple codes, use the boolean OR syntax like this:
keywords:
(035255848701,035255869027)
When shopping European countries, you should use the EAN number. The UPC code can be converted to EAN by adding a zero to the front. So the same search would look like this:
keywords:
(0035255848701,0035255869027)
Not all products are available in all countries.
One note about UPC codes on eBay: UPC codes are 12 digits long, and so are eBay item numbers. UPC codes have a check digit to validate them. It may happen that a UPC code and eBay item number match. In this case, eBay could return an unrelated eBay items page. In cases where UPC codes are not in the eBay database, the website may interpret the code as an eBay item number and display and error page. This does not occur with EAN codes which are 13 digits long.
