Modified data update service
The modified data update service is a service for public administration person registers that automatically updates changes recorded in the Population Information System to official registers. The modified data update service will be used until the end of 2024. It is replaced by the new PIS modified data interface.
The modified data update service updates customer organisations registers with the changes recorded in the Population Information System at certain intervals. The data can be updated once a day, every week or every two weeks, as required by the customer. Modified data updates can be retrieved either based on the region or personal identity codes.
The service is no longer offered to new customers. Municipalities can still order standardised products, but new registers will no longer be updated through the service.
Checklist before using the service
The data in the Population Information System is not public. Before ordering the service, read more about the prerequisites for using the data.
Follow these instructions
Public administration organisations must apply for a data access authorisation (link) before the commissioning of the modified data update service.
Municipalities, hospital districts and joint municipal authorities have been granted a general data access authorisation for the organisation's official duties. These organisations do not need to apply for an authorisation separately, as the service can be ordered through the e-service. When making the order, a report on data protection arrangements and the use of the data must be filled out.
Additional information about the service:
The processing time for municipalities' modified data update service's product orders is approximately one week.
