GS1 India offers a barcode verification service to enable comprehensive barcode diagnostics. This service helps organisations print and maintain bar codes that conform to ISO and GS1 specifications and ensures efficient scanning by any type of barcode scanner in a variety of scanning environments.

Verification should ideally be carried out at the artwork stage, prior to bulk printing and thereafter once in a year to ensure consistency in print quality in different print runs. Verification is carried out by an ISO compliant verifier, followed by additional minute observations on several criteria like print contrast, magnification, light margins, bar width, representation, check digit calculation, etc. keeping in mind GS1 specifications.

At the completion of testing, a bar code verification report is issued. Recommendations for changes, if necessary, are suggested in the report. GS1 verification reports are accepted by retailers globally and are even a pre-requisite for acceptance of products by many of them.


  • GS1 India barcode verification service helps organisations:
  • Get their products accepted by retailers worldwide
  • Save costs of (a) reprinting due to bar code failures and (b) delay and possible order loss
