The Population Register Centre provides information services to citizens as well as to government, businesses and other organisations on the basis of data contained in the Population Information System. The Population Information System is the most used national base register in Finland and it has been designed specifically to serve government information needs. It is also used for purposes such as academic research. The Population Register Centre produces services aimed at businesses and other organisations in cooperation with its partners. The Population Information System is used for purposes including updating of customer registers and direct marketing.
For secure e-transactions, the Population Register Centre creates an electronic identity for Finnish residents when providing them with a personal identity code. The electronic client identifier is used for electronic user identification in secure online transactions. It is activated when you get a card – such as an ID card – featuring the Citizen Certificate issued by the Population Register Centre.
