Information on the Positive credit register for software developers

The new legislation is not yet adopted

The legal act that will govern the Positive credit register is being prepared. Statements and opinions were received in spring 2021 from stakeholders in order to finalise the Finnish government's proposal to the Parliament. According to plan, the Register will open in early 2024.

Principles of technological design and function

  • The legislation that will govern the Positive credit register is being drafted. According to the draft, the planned effective date is 1 August 2022 but the legislation will not be applied in full until the spring of 2024 when the register is expected to be ready for implementation. The legal act on the Positive credit register, currently in drafting, will contain provisions that determine the register’s principles of operation. The continued drafting of the Government proposal is under way and the proposal should be presented to the Parliament by the end of 2021.
  • To plan and maintain the future register is the responsibility of the Finnish Tax Administration’s unit called the Incomes Register Unit.
  • The Positive credit register saves information and processes it for purposes defined by law. One of the products of the processing is to compile a data extract containing personal credit information – the credit register extract.
  • Registered data will only be available to the organisations that are entitled to this by definition of law. In the same way, the data can only be used for purposes enumerated in the law.
  • The parties that send information to the Positive credit register must do so because of a new, legally defined information-reporting requirement.
  • The law will provide that registered data can only be used against a charge.
  • The transfer of information will be based on a high level of automation.
    • Lenders will submit information through system interfaces. The information cannot be submitted on a paper form.
    • Multiple interfaces are also used for transmitting the Positive credit register’s data dispatches to public authorities, and for the fulfilment of requests for credit register extracts.
    • In addition, a special e-service will be built for private individuals. This gives everyone the right of access to the data which has been collected concerning him or her. The e-service will also comply with today’s accessibility requirements.


A number of interfaces between IT systems will help transfer information between the concerned parties and the Positive credit register. The following interfaces are planned:

  • Reporting interfaces for credit institutions, lenders, etc.
  • Another interface for credit institutions, etc. where they can make requests for credit register extracts.
  • Several interfaces for the public authorities that use the registered data.
  • A system interface for control of the register’s operation.
  • An interface for companies that provide credit rating services, for transferring data on voluntary credit bans.

Organisations will need certificates to use an interface. The certificate provides a means for the Positive credit register to ascertain an organisation’s identity.

The interfaces will function in English only. However, user instructions will be issued in Finnish, Swedish and English.


The Positive credit register will be opened in spring 2024, and we will release the technical documentation of its interfaces at least one year in advance, by January 2023.

Credit institutions must sign up as users of the register by autumn 2023.

Credit institutions send information on their existing loan contracts between 1 February 2024 and 31 March 2024.

Registered data will be available to its users as of 1 April 2024.

Working together with stakeholders including invitations to extensive test sessions

We find that close cooperation with the Positive credit register’s future stakeholders is important. Our stakeholders will have many opportunities to make comments about the design and provide important feedback in order to optimise the technological solution. To disseminate information on the status of the project, we arrange webinars and other events.

As the development progresses, the stakeholders can conduct tests with the Positive credit register system to ensure mutual compatibility. The start of the register’s testing is to be announced.
