In the pharmaceutical industry, GS1 emerged as the leader within recent years, setting the standard for product identifiers. GTIN is one of the GS1 terms for identifying a product. GTIN stands for Global Trade Item Number and consists of GS1 issued company prefix and a company issued item number, which makes the number globally unique.
For pharmaceutical companies, getting a GTIN is the first step towards serialization. But that is not all. Many countries do conform to standards for serialization. Examples of this include the United States, South Korea, Saudi Arabia. and the European Union. Some countries however do not align to GS1 standards, such as Brazil and China.
