The EAN-13 barcode is used worldwide for marking products often sold at retail point of sale. The numbers encoded in EAN-13 barcodes are product identification numbers, which are also called Japanese Article Number (JAN) in Japan. All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they are used to uniquely identify a product.

Each EAN-13 barcode consists of a 13-digit number that is divided into the following sections:

• The first two or three digits represent the country code assigned by the GS1 to a national or geographic region's GS1 member organization.
• The next digits (the rest of the first six or seven digits) are the organization or company code, assigned by the national GS1 organization.
• The following five or four digits are the product code, assigned by the company itself.
• The last digit is the check digit, used to verify that the barcode has been scanned correctly.
