Create a real, scannable UPC-A barcode for a retail product, Amazon FBA listing, or store shelf. Type your 12-digit UPC (or 11 digits and we add the check digit), and the barcode renders instantly right in your browser — then download it as a crisp SVG for print or a PNG for the web. Nothing you type is ever uploaded.
How the upc barcode generator works
Type your product's digits and the page draws the UPC-A bars directly in your browser using a barcode-encoding library. The 12th digit is a check digit calculated from the first 11 using the standard GS1 mod-10 formula, so if you enter only 11 digits we add the correct one for you.
About UPC Barcodes
UPC-A is the barcode you see on almost every product sold in U.S. and Canadian retail. It encodes 12 digits: a number system digit, a manufacturer code, a product code, and a final check digit. Amazon FBA, Shopify, Square, and most point-of-sale systems read UPC-A natively, which makes it the default choice for physical products and the most-searched barcode type by a wide margin.
Frequently asked questions
- How does the UPC barcode generator work?
- Type your product's digits and the page draws the UPC-A bars directly in your browser using a barcode-encoding library. The 12th digit is a check digit calculated from the first 11 using the standard GS1 mod-10 formula, so if you enter only 11 digits we add the correct one for you.
- Is the UPC barcode scannable and free to use?
- Yes. The output is a standards-compliant UPC-A symbol that any retail scanner or phone app can read, and there is no charge, watermark, or signup. Download it as SVG or PNG and use it on a label, package, or listing.
- Where do I get the UPC number itself?
- This tool encodes a UPC you already have into a barcode image — it does not assign you a brand-owned number. For products sold in major retail, UPCs are licensed from GS1. For internal inventory or marketplaces that allow it, you can encode any valid 12-digit number.
- What's the difference between UPC-A and EAN-13?
- UPC-A is the 12-digit code used mainly in North America; EAN-13 is the 13-digit international superset (a UPC-A is just an EAN-13 with a leading zero). Use the EAN-13 generator if you need the 13-digit European format.
