Verification

Verification is an important quality control tool, helping to ensure that your barcode, image or product data is compliant and won't cause any delay in the supply chain process.

GS1 offers three types of verification:

  • Barcode verification
  • Image verification
  • Product data verification

These may be requested on their own or bundled in the ProductFlow service.

A test that GS1 performs on a sample of your product in its package to ensure the correctness of the number and the physical attributes of the bar code  - size, height, location, reflective properties etc. The test assesses the correctness and integrity of the encoded number and data and the actual scanning performance of the barcode symbol. Barcode verification is best performed on an example of the completed product (“full” verification) but may be provisionally performed on artwork (“interim” verification) which should be followed up with a test on a completed product when available.

The following information will help you understand any difficulties reported for your Barcode Verification Failures.

Image verification is a part of the verification procedures performed with the ProductFlow service.

Image verification inspects photographs of your products to ensure they comply with the provisions of the GS1 Image Specifications and any requirements of the trading partner/s in each case. 

The following information will help you understand any difficulties reported for your Image Verification failures.

Note: GS1 can take photographs for you on request to ensure compliance from the outset and save you the overhead of arranging these product images yourself. For more information about the Photography service click here.

Product data verification is a part of the verification procedures performed with the ProductFlow service.

Product data verification provides an examination of your National Product Catalogue (NPC) product data to ensure compliance with the specifications of the NPC Data Dictionary, GDSN Package Measurement Rules and any industry and trading partner requirements. Data verification is required to ensure that your customer receives accurate data that has been gathered according to the various guidelines and specifications that apply in your trading relationship.

The following information will help you understand any difficulties reported for your Product Data Verification Failures:

  • Data: Your report will indicate which part/s of your product data are incorrect. Data will fail where it does not comply with the specifications of the GS1net Data Dictionary. Compare the stated reason for your data verification failure with the relevant section of the guide.
  • Dimensions: Dimensions must be entered in millimetres with product sides, tops etc. defined according to the GDSN Package Measurement Rules.
  • Tolerances: Your aim should be to achieve the greatest possible accuracy. However tolerances for dimensions and weight are defined in the GDSN Package Measurement Rules

The following information will help you understand any difficulties reported for your product data verification.

Note: GS1 can collect your product data for you on request to ensure compliance from the outset and save you the overhead of providing this information. This option is provided as part of the ProductFlow application process.


Barcode: Verifying barcodes to the GS1 specifications is best practice for anyone who uses them. Retailers receive confirmation that the barcodes will scan reliable and that the data they contain are correct. Suppliers can be confident that their products will meet all scanning-related and identification accuracy requirements. In Australia and New Zealand all the major grocery companies require GS1 barcode verification on all new products and whenever a change is made to a listed product. The requirement is being adopted by hardware and other retailers also. 

Image: Foodstuffs and Progressive Enterprises use our Digital Asset Management Service as an image repository and require full compliance with the relevant technical specifications. GS1 image verification checks not only these technical aspects but also assesses the adequacy and quality of the photography for the users’ requirements.

Data: GS1 data verification assures you and your partners of the accuracy of your product data for National Product Catalogue purposes.

Barcode: You apply for tests through your members’ MyGS1 portal or if you are non-member by completing the Non-member Request for Verification form. Then you send GS1 a complete sample of your retail product ready for market. This is the preferable test situation. If there is only artwork, a label or an empty packet available the test can be performed on this but location may not be assessed if it is not evident. Reports are still usable in this event.  Note that the report issued on artwork is headed “Interim” and must be followed up with a report on a complete product as soon as one is available. Higher levels of packaging may be sent empty and folded but note that weight cannot be assessed in this event.

Image: If you want GS1 to photograph the product you must send GS1 a complete sample of it ready for market. Otherwise you must either send the image that your supplier has taken or refer GS1 to the product if it already loaded to SmartMedia.

Data: If you want GS1 to collect and record the data you must send GS1 a complete sample of your retail product ready for market. Higher levels of packaging may be sent empty and folded but note that weight cannot be assessed in this event. If you want GS1 to verify data that you have collected and entered yourself you make application in the usual way.  

If you are not a member of GS1 you will have to fill in the Non member request for verification form and send it back to us.
