Barcode Validation

Because of the defined specifications for barcode symbologies, BarTender may not accept certain data input for your barcode. If the input contains excessive, insufficient, or invalid characters, the barcode displays a red X, and a description of the error type is displayed when you point to the barcode. These error indicators appear for all UPC/EAN/JAN, GS1 Composite, GS1 DataBar, Interleaved 2 of 5, ITF-14, MaxiCode, and Micro QR barcodes. For all other barcodes, invalid characters appear as a series of zeroes.

Therefore, it is important to note the restrictions of the symbology when you select the data source, because some symbologies may be better suited to display that data than others. For more information about character and length restrictions for each symbology, refer to Barcode Symbologies (opens in an external browser window; requires an Internet connection).
