What is RF?
The Russian Federation is an abbreviation of the "Russian Federation". Since this is the name of the country, the abbreviation of the name is also written with capital letters.
However, from the point of view of the law, this formulationis not normatively established, since the name of the state is specified in the Constitution, and it does not specify this reduction and does not specify what the RF is. In official documents, the title should be written completely.
