Pick Code 128 for the most compact labels, Code 39 if your inventory software expects it, or Data Matrix for very small items. Paste your SKU or asset list with a description column, choose a sheet such as Avery 5167 (80 per page) or L7651 (65 per A4 page) and print. Sequential tags are easy: build the list in a spreadsheet and paste it in.
Verified before you print
BarcodeKit draws every barcode from one precise geometry model, then reads it back with ZXing, an open-source scanner engine running in your browser. PNG, SVG, true-size PDF and EPS downloads all come from that same verified geometry, so what we check is exactly what you print.
Private by design
Nothing you type or upload leaves your device. There is no account, no server-side processing and no tracking of your product numbers.

Frequently asked questions
Which barcode is best for inventory?
Code 128 for most SKU and bin labels. Use Code 39 only if your scanner or software requires it, and Data Matrix when labels must be smaller than about 25 mm wide.
How do I know the barcode will scan?
Every barcode is read back by an open-source scanner engine (ZXing) right after it is drawn, from the same geometry we export. If the decoded value does not match what you typed you will see a warning before you download.
Is BarcodeKit free?
Yes. Generate, verify and download barcodes as PNG, SVG, PDF or EPS with no account, no watermark and no sign-up.
Are my barcode numbers uploaded anywhere?
No. Barcodes are drawn and checked entirely in your browser. Your product numbers, SKUs and CSV files never leave your device.
Do you sell UPC or EAN numbers?
No, and we recommend you never buy them from resellers. Official UPC, EAN and GTIN numbers are licensed by GS1, the standards body. Amazon and most retailers check numbers against the GS1 database and can reject recycled ones.
