System ID no.
PLEASE NOTE! Only public authorities can apply for a system ID number according to article 11 of the Act on the registration of individuals nr. 140/2019. Applications for system ID numbers received from legal entities that are not considered public authorities will be denied on the grounds of the aforementioned law.
If you are an EEA/EFTA citizen who intends to work in Iceland for less than 3 months, for an employer who pays salary-related expenses for your work in Iceland, a public authority will apply for a system ID No. for you. A tax card is issued when a system ID No. has been allocated. You cannot apply for a system ID No. yourself. The system ID No. does not grant you any rights in Iceland and does not confirm your right to stay.
