EAN/UPC Barcode Format
We normally supply barcode numbers in 13 digit EAN-13 format, with a leading 0 (eg 0799439112766 ). However, these numbers can also be used in 12 digit UPC-A format without the leading 0 (eg 799439112766 ). The actual bars produced for both of these are identical (see the picture below).
Outside of North America it is most common to print the barcode on products in the EAN-13 format. However, some retailers have software systems that don’t like numbers with a leading 0, and hence they will prefer to use your barcode in the 12 digit format (eg 799439112766 ). This is fine – the number is still the same and still unique and will work OK. You can let the retailer work out which version of your barcode number they would like to use.
If you need barcode packages (with the images, certificate of authenticity & registration), please use the following links: EAN-13 Barcodes Package, UPC-A Barcodes Package, CD Barcodes Package, DVD Barcodes Package, ISBN Book Barcodes Package and ISSN Magazine Barcodes Package.
We also recommend you to register free your product info in IBNREG – International Barcodes Network Registry, which will allow your customers to find the product info before buying it, by scanning the barcode with the Zebra Barcode Scanner application, available for iOS and Android.
