Barcode generator

Make one barcode or a whole list for your products, and print them on sticker sheets.

Any letters and numbers. Best for your own stock codes.

Or make a numbered series

Your files never leave your device. Everything happens in this browser tab. Nothing is uploaded, and closing the tab erases it.

How it works

  1. Choose the type: Code 128 for your own stock codes, EAN or UPC for products you sell in shops.
  2. Type a code, or paste a list with one per line. Or make a numbered series like SKU-0001 to SKU-0100.
  3. Download PNG or SVG files, or a PDF sheet of labels to print on sticker paper.

Questions

Which barcode type should I use?

Code 128 for your own stock, shelves and parcels: it takes letters and numbers. EAN-13 (Europe and most of the world) or UPC (US and Canada) for products sold in shops. ITF-14 for outer cartons.

Are these barcodes valid for selling in shops?

The picture is correct, but a shop needs a number that belongs to you: you buy those from GS1, the organisation that issues them. This tool draws the code; it can’t give you a registered number.

Will they scan?

We scanned each type made here with Apple’s Vision barcode reader on 7 Nov 2026. Print at 100% with no page scaling, black on white, and try one label with your own scanner before you print a thousand.

Do I need the check digit?

No. For EAN, UPC and ITF, leave off the last digit and Dozo works it out. If you type it and it’s wrong, Dozo tells you instead of drawing a code that won’t scan.

How many can I make at once?

There is no limit we set: paste as many lines as you like. Series go up to 5,000 at a time. Everything runs on your device, and no account is needed.

Is my list uploaded?

No. The codes are drawn inside your browser, so your product list stays on your device.
