Iceland State Codes

When dealing with addresses or locations in Iceland, our API uses the following state codes. These codes are based on the ISO 3166-2:IS standard for Iceland's regions (landsvæði).

Usage Notes

• Iceland is divided into 8 regions (landsvæði)
• All codes follow the format 'IS-' followed by a single digit (1-8)
• The Capital Region (IS-1) includes Reykjavík and its surrounding municipalities
• Each region serves as both a statistical and administrative division
• The regions are used for planning and statistical purposes

Regional Organization

• The Capital Region (IS-1) is the most populous and includes the Greater Reykjavík area
• Regions are organized geographically:
  • IS-2 through IS-4 cover the western parts
  • IS-5 and IS-6 cover the northern parts
  • IS-7 covers the eastern part
  • IS-8 covers the southern part
• The Westfjords (IS-4) is geographically distinct, forming a large peninsula

Administrative Structure

• Each region contains multiple municipalities (sveitarfélög)
• The Capital Region has the highest concentration of municipalities
• Regions serve primarily for statistical and planning purposes
• Municipalities, rather than regions, are the main administrative units

Data Usage

• When specifying locations in Iceland in your API requests, please use these exact codes
• Regional codes are simple single-digit numbers following 'IS-'
• While municipalities handle most administrative functions, regional codes are important for:
  • Statistical reporting
  • Geographic organization
  • Regional development planning
  • Address standardization

Note: While Iceland has undergone municipal mergers over the years, these regional divisions remain stable and are widely used for statistical and organizational purposes.
