Are your Barcodes suitable for all retail products?
The only kinds of retail products that don’t use EAN-13 Barcode Numbers are Magazines and books. Any other products use EAN-13 or UPC-A Barcodes – You can buy these on this page.
In most cases it will be better to use EAN-13 barcodes, as these are used in all countries except for the USA. If you are primarily selling your product in the USA then you may wish to purchase UPC-A barcodes. The differences between these formats can be seen here.
