In order to define your products with a number that has International Validity, you need to make a BARCODE NUMBER application to the Turkish Union of Chambers and Exchange Commodities and take a barcode number up to 9 digits (up to 1000 types of products). This 9 digit barcode number given to you can be re-designed based on your number of products as 13 digits in total by adding 4 digits to the end with the help of a program used by master film producers, printing houses or advertising companies.
