From a GTIN list to QR codes

I'm Daniel Carlman. This episode: turning a list of GTINs into links your label supplier can print as QR codes.

The generator is at dppagent.com/gs1. Upload a CSV, Excel or JSON file. It recognises columns such as GTIN, batch and serial. Check the mapping, and set the domain your links will use.

Then choose the level. Model: one link per GTIN, slash zero one. Batch adds slash ten and the lot number. Item adds slash twenty-one and a serial number, from your file or generated.

Before you export, check your GTINs. The last digit is a check digit, calculated from the others. The generator does not test it, so a typo goes straight onto the label.

A GTIN is never reused. GS1's rule, in effect since 2019, is that an allocated GTIN shall not be given to another product. So the link keeps pointing at one product.

Seeing and exporting the links needs the plan that includes publishing. You export Excel or JSON and send the file to your label supplier, who prints the QR codes from the GS1 Digital Link column.

One more thing. GS1 Digital Link is one way that EN 18219 accepts for the product identifier. It is not the only one.

I'm Daniel. See you in the next episode.

Next time: what applies to my products, and when? This is not legal advice.
