The geographical name Czechia was officially announced when the state started to exist on its own in 1993. The reason why it is not known is because the Czech state and its institutions have not used it. A short country name that is not used by the state itself and by its institutions cannot become well known and recognized abroad.
Czechia is listed in UNTERM.
