According to the survey of 4,300 people commissioned by the company MySafety, 2.8 percent of respondents said fraudsters had used their identities to steal money or buy goods.
This was an increase from 2.3 percent reported last year.
Ingegerd Widell from the Swedish Tax Agency, said that victims often found it difficult to repair the damage identity theft caused.
“For those I’ve spoken with and listened to, this has been awkward, uncomfortable and time-consuming to sort out – and to get all these different companies to understand that all this was not done by them but by someone else,” she said.
She said that one solution was to order a “digital postbox” for post from Swedish government agencies to make it more difficult for fraudsters to get hold of personal information by stealing post.
She said the worst thing people could do is to save the code for their Bank-ID in a file on their computer or phone.
