Decertification of standard franking machines


What is Royal Mail decertification of Non-Mailmark franking machines?

From 1st January 2023, Royal Mail will no longer accept mail from some models of franking machines. Mail franked by franking machines that don’t use Mailmark, a form of 2D barcode, will no longer be accepted.

How do I tell if my franking machine will be affected by Royal Mail decertification?

The difference between a standard franking machine and Mailmark franking machine is the meter impression it prints on your mail.

A Mailmark franking machine uses a 2D barcode shown below.

Whereas a standard franking machine uses an indicia.

If your franking machine prints a meter impress that looks like the image above without a 2D barcode (Image B), then you need to consider another franking solution to meets your needs. If you’d like to find out more about Mailmark click here.

Why is Royal Mail decertifying Standard Franking Machines?

All Royal Mail franking machines are moving to Mailmark, a form of 2D barcode, which is the most efficient and accurate way of processing mail. To hear more from Royal Mail about decertification, click here.

Which franking machine models will be affected by decertification?

If your franking machine prints an indicia, you will need to upgrade your machine. Please find the full list below of machines that will be affected.

If your franking machine prints a Mailmark barcode, and is not listed below, you do not need to upgrade your machine or take any action. Royal Mail will continue to accept your mail after 1st January 2023 as normal.
