Even though the names are different, Kristiansand is often noted as '''Kristiansand S''' (S for South) to distinguish it from [[Kristiansund]], also in Norway, in such cases noted as '''Kristiansund N'''. The practice originated before [[postal code]]s were introduced, as mail sometimes was sent to the wrong city. Occasional mix-ups with the Swedish city of [[Kristianstad]] have also been known to happen.http://news.bbc.co.uk/2/hi/europe/765629.stm
