The parish of Hvideseid was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). The spelling of the name was later changed to Kviteseid. On 11 October 1873, an unpopulated area of Kviteseid was transferred to Seljord Municipality. The boundaries have not changed since that time.

The municipality (originally the parish) is named after the old Kviteseid farm (Old Norse: Hvítingseið) since the Old Kviteseid Church was built there. The first element comes from the old name for the lake Kviteseidvatnet. That name is the plural genitive case of the word hvítr which means "white" or "the white one". The last element is eið which means "isthmus" or "path between two lakes". Prior to 1889, the name was spelled "Hviteseid".

The coat of arms was granted on 27 November 1987. The official blazon is "Or, a lock plate sable" (Norwegian: På gull grunn eit svart låsskilt). This means the arms have a field (background) has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used. The charge is a black lock plate. The lock design is based on one from the Tveitloftet medieval storehouse on the local Tveit farm dating back to the year 1350. The design symbolises the long traditions of lock-making and building construction in the area. The arms were designed by Daniel Rike. The municipal flag has the same design as the coat of arms.

The Church of Norway has one parish (sokn) within the municipality of Kviteseid. It is part of the Øvre Telemark prosti (deanery) in the Diocese of Agder og Telemark.
