Royal Mail fail to scan barcodes at the destination, no help from Royal Mail they are helpless.
Email from RM, I hope this helps guys:
I hope you are keeping safe and well. I am sorry to hear about this situation with regards to the scan rate.
What I can confirm is that we are working towards improving the scan rates and to identify any issues that may be caused lower than expected scan rates to occur. With your situation, I would suggest passing on the information to the MyServiceTeam so they can start up an investigation to identify the reasons for this lack of scanning. I will send over an email with their contact details shortly.
In the Short term, another solution is to use Amazons Buy Shipping portal to generate the labels and manifest. By doing so, Amazon acts as a shipping solution who would then generate and print off your Royal Mail Labels. In doing so, Amazon would consider these items as valid and they would not Affect your Valid Tracking Rate Score. You will still be billed as normal with your Royal Mail account and the only major difference is that Amazon would print out a separate manifest for the Amazon items. I would suggest packing the Amazon items separately if you do go ahead with this option.
I hope this helps to answer your enquiry.
