The article is devoted to a comparative legal analysis of the provisions of the criminal pro-cedure legislation of individual member states of the Commonwealth of Independent States (the Russian Federation, the Republic of Belarus, the Republic of Azerbaijan, the Republic of Armenia) related to the seizure of a subscriber device or access to information stored in its memory for the need to obtain a court decision or sanction the prosecutor. Attention is drawn to the difference in terminology, names and powers of participants in criminal proceedings, types and features of in-vestigative and other actions, during which the right to privacy of correspondence is limited. The studied models of access to information stored in the memory of the seized subscriber device allow us to conclude that the experience of the Russian Federation is most acceptable for balancing the interests of the individual, society and the state.
