Barcode Generator

EAN-13 (or UPC-A in North America) for products sold in shops, ITF-14 for shipping cartons, Code 128 for your own labels, serial numbers and shipping, Code 39 where older equipment requires it. For a lot of data in a small space, use Data Matrix or a QR code; PDF417 appears on IDs and boarding passes.

Not for products sold in shops. Retailers require numbers licensed from GS1, the organization that assigns them, so each number belongs to one company. Made-up numbers can clash with real products. For internal use, like stock in your own warehouse, Code 128 is a better choice.

The last digit of EAN, UPC and ITF-14 numbers is calculated from the others so scanners can catch misreads. Type the number without it and it’s added for you; type it with it and it’s checked.

Retail barcodes are designed for a module (the narrowest bar) of 0.33 mm, which makes an EAN-13 about 38 mm wide with its margins; they may be printed from 80% to 200% of that. The size shown under the preview assumes 0.33 mm. Use SVG for print: it stays sharp at any size. Always test-scan before printing many labels.

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
