Barcode verification explained: ISO 15415, 15416 and GS1
A barcode that will not scan at the distribution centre is not a printing problem, it is a chargeback problem. Verification is how you prove your codes pass before the truck leaves.
What a verifier actually does
A barcode verifier measures a printed code against the ISO/IEC standards (15416 for linear codes, 15415 for 2D) and grades it A to F. Retailers and DCs specify the minimum grade they accept; the verifier produces the report that settles any dispute.
Why scanners are not verifiers
A scanner just needs one good read. A verifier measures contrast, modulation, defects and decodability the way the standard defines them. A code your counter scanner reads fine can still fail at a DC with different equipment.
GS1 and compliance
If you supply GS1-regulated categories, verification reports are increasingly part of the trading agreement. An Axicon verifier on the packing line catches failures while they cost cents, not chargebacks.
