Barcodes Singapore provides EAN-13 barcodes.
For a full range of other barcode products (such as barcodes for books and magazines) and services, visit the International Barcodes Network site. Services include barcode registration (if you’ve bought your barcodes from somewhere else), barcode verification (for getting your product into some larger retailers) and giving general advice on how to barcode your products.
They may also be able to supply barcode labels, depending on your location. This can be very useful if you have already printed your product packaging at the time of purchasing your barcodes, in which case sticky barcode labels can be applied.
