when creating a store in brand registry with unique products and using upc barcodes is there a requirement to use any other barcode or can the upc code do it all?
Also does it matter what type of adhesive is used for a thermal upc bar code label?
No need to use any other barcodes.
The type of adhesive you choose should be compatible with the material of your products and the conditions they will be exposed to during storage and shipping. But there are no specific requirements.
Amazon requires the labels to be removable.
We use a Dymo LabelWriter 4XL. and Dymo 30334 Multi-purpose labels. They are perfect.
