About the CODABAR Generator

The CODABAR Generator creates a scannable CODABAR barcode image from any text or number you enter, ready to download and use in blood banks, libraries, and FedEx shipping.

CODABAR (also called NW-7) encodes digits and six special characters with no check digit built into the base standard, relying on external validation instead.

Developers, warehouse operators, and businesses use this generator to produce real, standards-compliant barcode images without needing dedicated barcode software.

Where CODABAR Is Used

Different barcode symbologies exist because different industries have different requirements — data density, character support, error tolerance, and printing space all vary by use case. CODABAR was designed and adopted specifically for blood banks, libraries, and FedEx shipping, which is why it remains the standard choice in that context.

Choosing the right barcode format for your application matters, since scanning equipment and industry standards are often built around a specific symbology.
