Staying less than 3 months
If you are an EEA/EFTA citizen who intends to work in Iceland for less than 3 months you need to contact the Iceland Revenue and Customs regarding the application of a system ID number.
Information about system ID numbers as well as normal ID numbers can be here.
Only public authorities can apply for a system ID number for foreign citizens and applications must be submitted electronically.
More information can be found on the website of the Registers Iceland.
Please note that a copy of passport or legal travel ID must be included in the application and the ID must be valid at the time the application is submitted.
Note that a system ID number is only issued to individuals who intend to stay less than 3-6 months in Iceland or do not intend to stay in the country at all. This registration does not grant any rights in Iceland.
