Unique identifier:

International GMO identification code

Every GMO that receives authorisation is given a "unique identifier" consisting of nine letters and/or numbers. The first two or three characters indicate the company submitting the application, while the final five or six characters specify the respective transformation event. The last digit serves as a verifier.

If GM content exceeds thresholds, the appropriate identification code(s) must accompany GMO shipments. The code can be used to retrieve information about the respective GMO from international databases.

The identification code, known internationally as the unique identifier, was established by the OECD (Organisation for Economic Co-operation and Development). The OECD is now overseen by the EU and forms the basis for the legally mandated system of traceability.
