If you plan to live and work in Iceland, you must register your legal domicile in person at Registers Iceland within 7 days of your arrival in Iceland. This applies to citizens of all countries.
You will need to present identification and all required forms and documents. For more information, see Registers Iceland.
PLEASE NOTE THAT REGISTERING YOUR LEGAL DOMICILE IS NOT THE SAME AS APPLYING FOR AN ID NUMBER, and vice versa. However, both are done at Registers Iceland and can usually be done at the same time.
