Why Verify Barcodes?

The benefits of having your barcode symbols tested.

The biggest benefits of verification are, simply, reassurance and confidence that the barcode will perform as intended at all stages of the product's movement down the supply chain, leading to untroubled supplier-customer relationships:

  • Reduced risk of print re-runs / wasted packaging and products
  • Confidence that printed barcodes will scan first time, every time
  • Improved read rates throughout the supply chain
  • More efficient movement of stock through supply chain.

Many large-scale operations and government agencies require barcode verification to ensure error-free data entry. If you are complying with these standards, barcode verification is necessary to prevent fines and maintain the standing of your contract.

Products submitted for testing should be presented in their 'final retail form' together with loose labels or unformed packaging. We test the barcode for compliance to the GS1 standards through a testing process based on the ISO 15416 verification (testing) method. This method assesses size, colour, print quality and quiet zones (light margins). We also assess bar height and the location/placement of the barcode. The barcode is also checked to ensure the right GS1 number and a correctly calculated Check Digit has been applied.

A GS1 Ireland's Bar Code Verification Report is issued at the completion of testing. The report indicates the compliance of your barcode and, if necessary, suggests where you may need to make changes to meet GS1 and industry specifications. For further information on the GS1 Ireland Barcode Verification Report please contact the GS1 Ireland Testing Services on 012080660 or email helpdesk@gs1ie.org.
