When printing Code 39, ensure that the code scans with a Code 39 Verifier (also known as a Code 39 Checker). Since the code does not contain a check digit, it is even more important to verify for readability down the supply chain.
However, Code 39 modulo 43 contains a check digit, but this feature must be enabled in the barcode reader. Whether your company is printing a regular Code 39 or a Code 39 modulo 43, it is important to have a barcode that scans. The only way to ensure 100% scanability is through barcode verification.
The following Webscan products can verify Code 39.
