The government agency websites are subsites of Ísland.is. They are tailored to user needs and aim to provide information regarding a government agency's services.

They are for government agencies that want to help their users directly access the content. The agencies also enjoy the advantages of sharing tools, such as the Island design system, content strategy, and the operational support of Island.is.

The websites use the design system to provide a uniform user experience. That includes users accessing the website both via desktop browser and a mobile browser, as well as those who use screen readers or text to speech software.

In addition to the design system, the Island.is content strategy supports clear presentation of services provided by the government agency. The content of all government agency websites is accessible to all users of Island.is via its search and navigation. This contributes to the objective that users do not have to navigate between the websites of different government agencies, but rather find what they are searching for quickly and easily at any given time.
