- We probably did not think that there would be so many.

The more we looked, the more we found in some way, says Anders Klaar, project manager and business developer at the Swedish Tax Agency's population registration unit.

In the pilot project, the Swedish Tax Agency, together with eleven other authorities on behalf of the government, has mapped out how incorrect population registration is used systematically in various criminal schemes.

Over 500 so-called strategic addresses that are used for such were found in the project.

150 identities have been used

Linked to the addresses, approximately 1,500 personal inquiries have been made regarding both social security numbers and coordination numbers that have been used incorrectly.

Among other things, this led to about 200 people being registered as emigrants and in 150 cases the suspects' identities have been used in various ways.

- It is another person who has used them.

If you have several identities, you can use them for fraud, take out a loan or have someone on the board of a limited company.

After a while, the company may go bankrupt and then we will not find the people, says Anders Klaar, project manager at the Swedish Tax Agency.

The identities that are used can take place both with and without the people's knowledge.

The review revealed, among other things, a number of foreign students whose identities were used to take out loans and to be goalkeepers after leaving the country.

Wants to be able to warn the Swedish Companies Registration Office

The report has now been submitted to the government.

Among other things, the authorities in the project want it to be investigated as soon as possible whether biometric data, such as fingerprints, should be linked to identities in order to reduce the risk of them being used.

Like that there will be less secrecy between authorities.

- If we at the Swedish Tax Agency see that this is probably an exploited identity, then we can not tell the Swedish Companies Registration Office, for example, that it is used there.

We would like to have that opportunity to be able to share information between authorities to prevent crime, says Anders Klaar, the Swedish Tax Agency.
