Also covers: EAN-13 barcode generator · UPC barcode generator · Code 128 generator · ISBN barcode
Retail products worldwide: 12 digits (the check digit is added) or all 13.
Retail barcodes (EAN, UPC, ISBN) must use numbers assigned to your company by GS1 or your national ISBN agency — a valid-looking number you make up can clash with a real product.
Use SVG for print and packaging — it stays sharp at any size. Keep dark bars on a light background, and leave the white margin on both sides: scanners need it.
EAN-13 or UPC-A for retail products, ISBN for books, ITF-14 for shipping cartons, Code 128 or Code 39 for labels and inventory.
For retail types, leave off the last digit and the check digit is calculated for you; a full number is checked for typos.
Adjust bar width, height, and colors, then download SVG for print or PNG for screens and documents.
Not for retail. Shops and marketplaces require EAN/UPC numbers licensed from GS1, and ISBNs come from your national ISBN agency. Code 128 and Code 39 are fine for your own internal labels and inventory.
The last digit of an EAN, UPC, ISBN, or ITF-14 code, calculated from the others so scanners can catch misreads. This tool calculates it, or tells you if the one you entered is wrong.
Scanners need a clear quiet zone (white margin) on both sides and enough contrast; very small or low-contrast barcodes fail. EAN-13 is designed around 37 × 26 mm; it can be scaled from about 80% to 200%.
