The search for a missing person is rarely limited to a single archive. Depending on the period of the person's life, the circumstances of their disappearance, and the historical events involved, documents may be located in different countries, departments, and archival institutions.
Information about the fate of one person may be distributed among several sources. For example, birth information may be stored in the Civil Registry Office archive, military service records in the military archive, and information about repressions or deportation in departmental archives.
When searching for missing persons, the following are most often used:- State Archives of Ukraine;
- Security Service of Ukraine (SBU) archives;
- Ministry of Internal Affairs (MVD) archives;
- Military archives;
- Civil Registry Office archives;
- Archives of enterprises and educational institutions;
- Foreign archives;
- International databases and documentary collections.
The list of archives is always determined individually and depends on the specific family history, available information, and the objectives of the research.
