What Is a UPC Barcode?
A UPC-A barcode is a 12 digit retail product barcode commonly used in the United States and Canada. The UPC number identifies a product, while the barcode image gives scanners a machine-readable way to read that number.
This free UPC generator is useful when you already have a UPC number and need a fast online UPC generator to create a clean UPC-A barcode image.
UPC-A vs EAN-13
UPC-A uses 12 digits. EAN-13 uses 13 digits and is common internationally. If your code has 13 digits, use the EAN-13 generator.
If you only have the first 11 UPC digits, use the UPC check digit calculator to calculate the final digit before generating the barcode.
