Each quite zone is 9 modules wide, the lead and trailing blocks are a series of lines and spaces in the format of bar, space, bar. In addition to the 13 digits, which make up a EAN-13 barcode, the barcode symbol also has two quite zones, a lead block, a separator, and a trailing block. Each digit is drawn within a space that is 7 modules wide.

Scaling the barcode will produce a barcode between the minimal allowable size of 29.83mm wide by 20.74mm high and the maximum allowable size of 74.58mm wide and 51.86mm high. Based upon this nominal size, the EAN-13 barcode can be scaled by a magnification factor of 0.8 to 2.0. The specifications for the EAN-13 barcode specify the nominal size as 37.29mm wide and 25.93mm high. The last or right most digit is '0' and is considered odd, so multiply it by 3, the second right most digit '9' is even so just add it, etc. This is subtracted from 10, and the modulus of 10 is taken again. The modulus of 10 is then taken of the summed total. The reason for the EAN-13 check sum being calculated in reverse order (starting with the right most digit and considering it as being odd instead of even) is for compatibility with UPC-A barcodes. The odd numbers starting with the right most digits are multiplied by 3 and added to the sum, while the even numbers are simply added to the sum. The checksum digit is calculated using the country code, manufacturer's code, and the product code. The product codes can be as few as 3 digits long, or as long as 5 digits depending on the length of the country and manufacturer codes. The manufacturer is free to assign its own product codes, but they must make sure that each product code is unique within their product codes. Typically, 5 digit codes are assigned to companies, however, some companies do not produce enough products to warrant a 5 digit product code, and in such cases the EAN will issue Manufacturer Codes longer than 5 digits. The EAN Manufacturer Code is a variable length number.

The following table contains the Country Codes: 00-13: USA & Canadaĩ77: International Standard Serial Number for Periodicals (ISSN)ĩ78: International Standard Book Numbering (ISBN)ĩ79: International Standard Music Number (ISMN) All EAN-13 barcodes that begin with "0" are UPC-A barcodes. The Country Code is a 2 or 3 digit number, which is used to identify the country that assigned the manufacturer code.

The figure below shows a typical EAN-13 barcode. The EAN-13 barcode is composed of 13 digits, which are made up of the following sections: the first 2 or 3 digits are the country code, the next 5 to 7 digits are the manufacturer code, the next 3 to 5 digits are the product code, and the last digit is the checksum digit. In this article, we will look at the EAN-13 specification and examine some code that can produce EAN-13 barcodes. This article came about as a response to a request to extend the UPC-A barcode example to include EAN-8 and EAN-13.
