Barcode Verification and Validation

bar-code-scanWhat’s the difference and why does it matter?

We take the ubiquitous barcode for granted and assume that a simple scan will give us all we need to know about the barcoded product. This assumption can be false, however. Your scanner might be able to read the barcode; some scanners have technology that enables them to scan and read even poorly printed barcodes. But that doesn’t mean your customer will be able to scan the barcode.

The way to ensure quality barcodes that are readable at any point in time is through verification. Verification tests and grades the barcode for quality, consistency and adherence to a specification standard. The quality test ensures the barcode is printed to a satisfactory quality (solidly printed bars, sufficient white areas and quiet zones, good contrast between the light and dark areas.)

When your barcodes pass the verification process, you know that the label or direct part marker is successful and will be readable further on in the supply chain.

Validation is a different process that assures that the barcode represents an actual product. Validation checks that the proper number has been printed as expected but will not tell you if the barcode is readable by all other barcode scanners.

Validation helps to reduce errors, such as re-assigning a number from one item to another within a product line, or making an error assigning a number to a product. Verification doesn’t detect such errors.

Both verification and validation are important because together they ensure accurate and readable barcodes. Still have question about barcode verification and validation? Then give us a call toll-free at: 888-438-3242 Option#3

  1. Greetings Linda!

    We are due to undergo some barcode scanning changes here shortly and I was curious if you could recommend any particular equipment and/or software for grading and validation? Thank you!
