When multiple barcodes are located on a pack, there’s always the potential for scanners to read the ‘wrong’ barcode or double scan the same product.
When implementing QR codes powered by GS1, the EAN or UPC barcode already on pack can remain where it is. Following on from that, there are three placement possibilities for placing the QR code powered by GS1, all of which are dependent on what the QR code will be used for:
Placement
The QR code powered by GS1 is intended to be scanned at point-of-sale (POS).
In this instance, both the EAN/UPC barcode and the QR code are intended to be used for the same application: POS. Wherever two symbols can be used for the same application they should be placed adjacent to one another.
The entire 2D barcode including Quiet Zones should be placed within a 50mm radius from the centre of the linear barcode.
The orientation (stack or row of symbols) or sequence (which symbol is placed on the left, right, top or bottom) is up to the brand owner.
Where adjacent placement on one panel is not permitted based on space limitations, try to place the two symbols on adjacent panels.
The QR code powered by GS1 is intended to be used for consumer engagement.
Wherever two symbols are used for different applications, they should be placed non-adjacent to one another.
In this instance, the EAN/UPC is going to be scanned by POS, whereas the QR is only intended to be scanned by consumers via their phones.
The QR code powered by GS1 is intended to be used for multiple applications.
The beauty of QR code powered by GS1 is that it is a barcode that can be used for multiple use cases. When the QR code will be scanned in multiple applications (e.g., point-of-sale and consumer engagement), placement for POS should take precedence.
See the POS tab for more information.

Whenever you see a ‘should’ in relation to GS1 standards, it is expected that organisations follow the guidance, but it is appreciated that they may not if there is a good reason not to.
An example of this could be Accessible QR codes which are intended to be used by the blind or partially sighted. In this instance, a QR code powered by GS1 that was intended to be used at POS and also for consumer engagement, should be placed adjacent to the linear barcode. However, placing the QR code on the front of pack (non-adjacent to the EAN) would be more optimal in this instance as it would be the only way the consumer could find the product in store.
