About Mailmark:

The Mailmark services give you access to even bigger discounts than those offered via the other mailsort services. When you upload the information to the Royal Mail eMHS system, you also benefit from a wealth of reporting and tracing facilities all the way down to each individual mail piece.

A Mailmark barcode must be printed on each mail piece. There are three types of 2D Matrix barcodes as shown below. Below are examples of the three 2D barcodes types produced by the system:

Format 29 2D:            Format 7 2D:            Format 9 2D:

Both the barcode generation feature and eMHS facilities are available via this website.

Process description:

The Mailmark process is split into three separate steps:

  1. Process Mailmark:
  2. Generate Barcodes:
  3. Manage eManifest:

NB!: Before you can access steps 2 and 3 you will need to enter your eMHS login credentials in the eMHS Setup section. As a minimum you need an eMHS test account. The Royal Mail may provide you with only with a production account, but if you also request a test account, it is a useful tool to try things out proir to going live. Accreditation tests are conducted using a production account (more on this further down this page).

Mailsort files generated:

Based on the data file uploaded (in comma separated format - csv), the system produces a number of result files. These consist of printable and uploadable reports, data files for producing the mail pieces, bag labels etc.

A subset of the complete result file set is made available free of charge, allowing you to assess the mailing properly prior to paying for the complete set. The data sets are listed below.

Mailmark Barcode Images:

Barcode images are the graphical representations of the barcodes that need to be printed on each envelope and that can be scanned by the Royal Mail when in transit. The Mailmark processing fees include the underlying barcode strings by default, but as an optional extra the system can also produce the barcode images as individual gif files, one for each record. You can then embed this file onto the mail piede directly without any other processing necessary (the address file contains links to the files).

Here is an example of how to use Mailmark barcodes in a mail-merge with MS Word (Youtube)

If you already have your own solution for producing barcode images and only need the barcode strings, you do not need this option. The processing time is also considerably shorter without this option.

DPS Matching Notice:

When processing for Mailsort with Barcodes or Mailmark, the fees include generation of DPS codes and full mailmark strings which are both included in the processed address file. The DPS codes are automatically derived by matching against the Royal Mail PIF database which is updated every six months.

NB! Please be aware that the Royal Mail does not offer any accreditation tests for this service. We can therefore only provide it on a 'Best endeavours basis' and it cannot be regarded as 100% accurate at all times.

If your data already has DPS codes included (must be in a separate column named "DPS"), you can tell the system to use that instead. For records where the DPS field is empty the system will try and find the DPS anyway, in the same way as described above. If your data has a DPS column, but you don't tick the "Use existing DPS" box, the system will ignore ignore this column and derive all DPS codes from the PIF database.
