Updating your customer register keeps you informed

We can help you update your customer register either with a one-time update or with a continuous updating solution.

Who is the service designed for?

If you are already our customer, find out the status of the addresses or telephone numbers in your consumer register using a free-of-charge register test in Posti’s Kontakti service. If you wish to update the register immediately, you can do that as well.


Up-to-date customer data is a prerequisite for productive customer relationship marketing and sales. When you have the correct name, address and telephone number information, your interaction with the customer becomes more efficient and your message is targeted better.

About one-fourth of all the information in customer registers expires each year due to, for example, moving, deaths and name changes. In the register update, we will provide any changed name, address and telephone number information of your customers as well as information on customers that have passed away, are minors or duplicates.

  • About 25% of customer data expires each year

  • The controller is liable for keeping the customer data up to date

  • Posti has the best service in the country for updating personal registers
