You can create the data matrix codes for Letter ID and Letter ID light in the “Create postage paid impressions” online service.

To create the dynamic Letter ID you need to import your recipient addresses. We will generate the appropriate data matrix code for them. The maximum number of data matrix codes that can be created per address upload is 10 000. 

If you are planning bigger mailings, it may be worth contacting a print service provider/letter shop, or creating the data matrix codes with your own software.

You can choose from the following options: 

• Digitization
• Disposal (simple and/or qualified) 
• Redirect mail 

Letter ID (dynamic code)

• Uniqueness − each consignment has an individual data matrix code.
• The production process should ideally use software since each consignment has its own code. Possibility of producing smaller volumes (10,000 addresses per dispatch) within the “Create postage paid impressions” online service.
• Alphanumeric digits may be used freely in the code by the customer.
• Individual information on returns and automated further processing possible.

Letter ID light (static code)

• The data matrix only needs to be created once. This can be done with ease using the “Create postage paid impressions” online service.
• No individual information on returns except if the individual images of the return shipments are viewed. In this case, an individual conclusion can also be drawn.
• Address maintenance via DataTransfer is not possible.

Send a data matrix code along with the letter layout to one of our “Final proof” Competence Centers in your region.

Verification is free and you will receive a written response within 72 hours. 

With the dynamic Letter ID, it is beneficial if you submit five copies for homologation to enable the dynamic filling-in process to be simulated. This is not necessary with Letter ID light since the filling-in process is always the same.

To post PP-franked consignments using Letter ID or Letter ID light, you use a dispatch list, which is simply a delivery note. 

For consignments using Letter ID light, simply enter “postage paid impression” as the “Dispatch type”. For consignments using Letter ID, by contrast, record the consignments using “postage paid impression with Letter ID” as the dispatch type and enter the order number integrated into the data matrix code Letter ID.
