Barcode Verification

Verification reports are test scan results of printed barcode images. These test scans are done with technical verification machines. The report states how well the printed barcode image scans. The barcode is then given a score – Passing grades are A, B, C or D. The report also gives specific information on the various parameters of the barcode so that your printer can tell what specifically may be wrong with the barcode (should this be the case). Some shops insist on barcode verification reports for every new product that enters their stores.

Our verification tests are performed using the latest verification equipment and technology to internationally accepted barcode standards. If your customer requests verification, make your order below & post/courier your barcode one its final packaging to us. Verification Reports take 2-3 days once we receive your barcode (the completed report will be emailed to you as an attached file).

Barcode Verification requires that your barcode images adhere to a strict set of regulations please see Barcode Dimensions for more details on what is required for your barcode to pass verification. If you wish to verify another kind of barcode (i.e ITF-14) please ask us about the specifications for other barcodes.

Please note that our verification machine can only verify EAN-13 and UPC-A barcode images that are between 80% and 135% magnification.

“Do I need barcode verification?”

Some retailers require barcode verification for all new products entering their stores (you need to check with your retailer to see whether this is required). Other companies conduct these tests themselves on new products they are accepting.

Verification reports can also be performed on your artwork prior to printing. This is a good way to determine whether your barcode is likely to be readable when it is finally printed. NOTE that verification reports on barcode artwork do not guarantee that the final printed barcode will scan well – as there can be errors in the final barcode printing process.

The safest process is to get a barcode verification report performed on your artwork, and then another verification report for your final printed product.

If you would like a verification report (for your artwork or final printed barcode), please purchase above & then send us a copy of your barcode. Post or courier the final printed barcode to us (as printed its label or packaging). Our address is on our contact page.


“How can I make sure my barcodes pass verification?”

About 12% of the barcodes our customers have sent to us in the past failed verification. The standards that a barcode needs to meet in order to pass verification are quite high. If you are getting your barcodes verified, please read the following information & ensure that your barcode complies with the barcode standards & verification criteria before sending it to us for verification:
1. The official barcode standards
2. How to pass barcode verification

Interpretation of failed reports:

We provide verification reports. We do not interpret failed verification reports. Please discuss your verification report with your printer.

The 7 parameters verification looks at;

  • Modulation – how much the contrast between black and white varies across the barcode as some parts can be blacker than others.
  • Defects – dark marks in white spaces and white marks on black bars.
  • Decodability – how accurate the different widths of the bars and spaces of the barcode are.
  • Decode – whether the light margins on each side (left and right white spaces), the encodation of data, and the check digit are all correct.
  • Symbol contrast – how black and white it appears to the scanning machine.
  • Minimum reflectance – whether the dark bars are sufficiently different from the white spaces (hence be careful when printing on coloured backgrounds).
  • Edge contrast minimum – The least distinct difference between a bar and a space.

A Barcode Verifier

A barcode verifier is not the same as a barcode scanner. A barcode scanner is typically a mass-produced item that interfaces with a computer providing machine recognition of the information (data) encoded in a barcode image. Using a scanner to test or read a barcode only assures that the scanned bar code has some area on it that is readable, by that barcode scanner. Hence, the better the barcode scanner, the less barcode quality assurance is maintained (eg a good barcode scanner could read a poor quality barcode image).

In contrast, a bar code verifier is a precision machine that is designed to predict how easily the barcode will be read by typical barcode scanners. The barcode verifier can decode, measure and check the quality barcode images of all qualities, and indicate any areas that need to be improved.
