In Estonia, imprisonment is broadly divided into three stages: the reception period, the main period, and the release preparation period. The purpose of the reception period is to prepare an individual action plan and help the prisoner adapt to prison life in the best possible way. 

In most cases, a prisoner begins serving their sentence in a closed prison, from which they may later be transferred to an open prison. No later than the first working day after arrival, the prisoner meets with a prison service official, who provides initial information about their rights and obligations.
