The code systems can be described by:

• how the area is coded (number, letter, mixture of both, other)
• which part of the earth is covered (whole earth, land, water, a continent, a country)
• what kind of area or location is coded (country, county, airport, railstation, city, ...)
• size of the area
• time for which the code is valid
