Colloquially, many know GTIN as a barcode, but technically, GTIN is the number found beneath the barcode symbol itself, and can therefore also be used for other technologies such as 2D barcodes and RFID tags.
A GRAI is the identification number used to identify types of reusable packaging or transport equipment that are considered assets, such as a container or a roll cage - but also equipment like a hospital bed or a portable ultrasound scanner.
A GRAI is used to track and collect data about each individual asset. This provides significant advantages when you always know exactly where your equipment is.
An asset keeps the same GRAI throughout its entire lifetime and can therefore be used to record maintenance intervals and similar information.
En identifikationsnøgle starter altid med et virksomhedspræfiks. Et virksomhedspræfiks er et GS1 ID, som du køber i Mit GS1.
Der findes virksomhedspræfikser i forskellige længder: fra 7 cifre til 11 cifre lange. Det varierer efter antallet af numre, som du har behov for.
Præfikset suppleres med et x antal cifre for at opnå en identifikationsnøgle (for eksempel GTIN).
Jo kortere virksomhedspræfiks, desto flere frie positioner har du til at identificere produkter med. Med andre ord, jo kortere virksomhedspræfiks, desto flere identifikationsnumre kan du oprette. Dette kalder vi 'nummereringskapacitet'.
Det sidste ciffer er et kontrolciffer, der bekræfter, at koden er korrekt.
See below what you need to do once you have received your company prefix of between 7 and 11 digits from GS1 Denmark and need to convert it into barcodes. First, you need to create the GTIN product numbers that the barcode will contain:
With 7 digits, you can create 100,000 GTIN product numbers
With 8 digits, you can create 10,000 GTIN product numbers
With 9 digits, you can create 1,000 GTIN product numbers
With 10 digits, you can create 100 GTIN product numbers
With 11 digits, you can create 10 GTIN product numbers

Nedenfor kan du se hvordan data synkroniseres imellem købere og sælgere vha. GS1 GDSN og GS1 Global Registry.
1. Loading of company data
2. Registering of company data
3. Subscription to seller's data pool
4. Publishing of company data
5. Confirmation receipt of company data
A GRAI can be encoded into a GS1-128 or GS1 Datamatrix barcode using the Application Identifier (8003).
