FI - Finland

Finland is divided in 19 Counties called Maakunta in finnish. They are grouped in 6 Regional State Administrative Agencies. The old Counties have been abolished.

Also the call-areas in some cases does not respect the old borders. Anyway today the division in call-areas lost their original meaning because many callsigns does not have any relation with a particular area or region. The Aland Islands are an exception. OH0 is always given to Aland Islands operators.

The best way to know which is the Maakunta is as usual Wikipedia
