What is the Barcode Generator?
The barcode generator creates standard barcodes for products, shipping cartons and inventory. Choose the format, type the data and download a sharp PNG or vector SVG for printing. Check digits for EAN-13, UPC-A and ITF-14 are calculated automatically.
Retail product barcodes (EAN/UPC) must use numbers issued by GS1 Pakistan or your country's GS1 office. For links and contact details use the QR Code Generator; for full shipping labels use the Shipping Label Generator.
