My personal data has been stolen or leaked
Make the necessary blocks

Protect yourself from any misuse
Once your personal data has been leaked online or ended up in criminal hands, it may be used to commit identity theft or fraud.
However, you can prevent abuse yourself by means of blocks. Consider prohibitions especially when your personal identity code is leaked.
Consider taking out a credit ban
A self-imposed credit ban is a paid service that is offered by two companies:
- Suomen Asiakastieto’s Oma luottokielto (self-imposed credit ban, page available in Finnish)Opens in a new window.
- Bisnode’s Oma luottokielto (self-imposed credit ban, page available in Finnish).Opens in a new window.
To ensure the comprehensiveness of your credit ban, it is good to use both services at the same time.
