Instructions for mailer companies

If the Sorting Service is not working properly, please wait a moment and try again. If this does not help, check your network connection. Kindly also check that the product information or other parameters you have provided were entered correctly. Erroneous information may cause disruptions.

If the disruption lasts for a long time, send an error message by email to lajittelupalvelu@posti.com and we will start fixing the problem immediately. The email is monitored during office hours on weekdays. If necessary, our specialists will contact you.

If your mailing schedule is flexible, please wait for the system to start working. If you cannot delay the mailing, follow these instructions:

1. Keep preparing the mailing batch with the help of the Guide for Batch-Sorted Postal Items or service-specific mailing instructions for letters. - Standard Letter Pro mailing batches are unitized in four directions (4k) according to Guide for Batch-Sorted Items: Loading of items into transport units, page 21.

2. Use the electronic mailing list – Magazines: continue filling out the mailing list created with PTP.  – Customer Direct: continue the mailing list created in advance for the mailing batch. If you do not have one, create a new one. – Priority Letter, Economy Letter or Priority Standard Letter: register the items on the mailing list. – Standard Letter Pro services: we will contact you and issue separate instructions.  

3. Note that the Sorting Service was out of use in the Additional information for mailing list handlers and Posti’s reception field. This ensures that we will not charge unnecessary additional service fees from you.

4. Also remember to mark the mailing list as completed and attach cover letters to the mailing batch.

5. Drop off the shipment lots at the posting place.

When preparing the items, find out and bear in mind the service-specific requirements of Posti’s mechanical handling, such as measure and weight limits and the placement requirements of 2D codes, 4-state codes and address information. In addition, the paper grade influences magazines’ and direct marketing items’ suitability for mechanical handling. See instructions on this page.
