Police have previously been able to scrutinise lists from the city of Malmö's marriage registrar with names, personal identification numbers and times for weddings.
Through the lists, the police would be to see if either of the spouses should be arrested and dismissed. The municipality has now decided to no longer include social security numbers in the lists.
"We have had a discussion and came to the conclusion that we want to protect the personal sphere," Tomas Bärring, secretariat director at the city office, told the newspaper.
The police can still have access to the personal identification numbers of those intending to marry by requesting a proof of impediment.
