Can a barcode appear multiple times on the packaging?

The manufacturer prints this barcode on the packaging. How does the manufacturer know that it isn't already in use? In principle, it shouldn't matter to the manufacturer; it's only the retailer who has problems, right?

A barcode is not awarded several times.

A barcode is composed of several factors and is like a “fingerprint”

The first digits of the barcode (also EAN) identify the country of origin and the company. You can’t just choose this. These are managed and awarded by GS1 Germany GmbH.

The barcode is strictly only one number, but here there are also differences in structure…

However, it can often be awarded several times. However, not the dealers but the manufacturers would get a problem, as the dealers would slim the articles out of the assortment

The barcode is identical on each packaging. Can also look at the packaging in the shop when you compare two packaging. This is simply a unique number that characterizes the article. Prices are not stored on the barcode.

No, of course not because there are 2 different articles.

But if you compare 2 packs of an identical article, then the bar code is also identical.

I honestly cannot imagine why this relationship is unclear.

That was your question, wasn’t it?

A certain part of the barcode is given by the manufacturer. This part is individual from company to company. And within the company you have a program that knows the barcodes you already have from your company and thus does not create a double.

Can’t happen. The first two figures stand for the country, the next five figures are awarded to one manufacturer. This sets out the following five figures for the product. The last number is a computational test digit.

The strips are the numbers, only machine-readable.
