How to Use the Barcode Generator
This barcode generator creates valid UPC-A, EAN-13, and Code128 barcodes from your data. All barcodes are rendered as scalable SVG files suitable for print and digital use.
Choosing the Right Format
Use UPC-A for US retail products — you enter 11 digits and the 12th check digit is added automatically. Use EAN-13 for international products — enter 12 digits and the 13th is calculated. Use Code128 for shipping labels, internal inventory, or any alphanumeric data up to 48 characters.
Generating and Downloading
Enter your data, click Generate, and the barcode appears immediately. Click Download SVG to save a vector file that prints at any size without pixelation. Use in Word, Adobe Illustrator, Canva, or any design tool that accepts SVG files.
Check Digit Validation
UPC and EAN barcodes include a check digit — a calculated value that lets scanners verify the number was read correctly. This tool calculates the check digit automatically, ensuring your barcode will scan successfully.
