Amazon uses various unique identifiers to link a product and its data. Where bol.com only uses the EAN and ISBN, Amazon is an international platform and therefore offers a wider range of unique identifiers.
In this article, we'll explain what all these unique identifiers mean.
ASIN stands for Amazon Standard Indentification Number. It is a number with 10 characters which consists of numbers and letters. Amazon assigns the ASIN to a product based on other identifiers such as EAN codes.
ASINs are unique within a specific marketplace. Since Amazon sees every domain name - such as .nl and .com - as a different marketplace, the same products can therefore have different ASINs.
EAN stands for European Article Number. It is a number with 13 characters which only consists of numbers. The EAN code is used throughout Europe in online and offline stores to provide products with a unique coding for the purpose of automating checkout handling and stock administration.
The EAN code can also be found under the barcode of the product.
UPC means Universal Product Code. It is a number with 12 characters which only consists of numbers. The UPC is only used in the United Stagen in online and offline stores to provide products with a unique coding for the purpose of automating checkout handling and stock administration.
The UPC can also be found under the product barcode.
ISBN stands for International Standard Book Number and is used as a unique identifier for books. The ISBN is similar to the EAN code, but can be recognized by the fixed prefix of numbers 978 and 979.
The ISBN can also be found under the product barcode.
PZN means Pharma-Zentral-Number and is used in Germany for the identification of medicines. The PZN consists of a prefix of PZN followed by 7 numbers.
The PZN can also be found under the product's barcode.
|GTIN||GTIN stands for Global Trade Identification Number and is the English variant of the EAN code, or literal translation. The GTIN is therefore the same as the EAN code and has the same properties.|
GCID stands for Global Catalog Identifier and is given to your product by Amazon to show that it is your brand. When you request Brand Registry, Amazon will assign the GCID number to your products. You can only use the GCID when adding a new product that is part of your approved list of registered brands.
If you are part of Amazon's trademark registration program, you will need to rent the EAN codes directly from GS1, as Amazon compares the EAN codes against the GS1 database for trademark registered sellers.
Use ASIN or EAN codes
Do you use the European Amazon marketplace? Then use the ASIN and / or EAN in case of an existing Amazon product. For a new product that is not yet known on Amazon, we recommend that you use the EAN code.
