Try Barcode Generator →Choose the correct barcode type
Different barcode standards have different rules. CODE128 can encode a broad range of characters, while EAN and UPC formats are commonly associated with retail numbering systems.
Generate the barcode
Choose the required format, enter the appropriate value, generate the barcode, and download the resulting image.
If the barcode will be used operationally, test it with the scanner or system that will read it.
A barcode does not create a product registration
Generating an image does not automatically assign or register an official retail product number. Businesses should use the identifiers required by their supply chain or standards organization.

What is CODE128?
CODE128 is a flexible one-dimensional barcode format capable of encoding letters, numbers, and other characters.
Can I simply invent a UPC for a retail product?
Retail identifiers may need to be assigned through the appropriate standards process; generating the barcode image alone does not register a number.
