St. Louis County is not the City of St. Louis. Confirm the place of death on the funeral papers. A city death mailed to the county, or a county death mailed to the city recorder, will bounce.
Who may request
Follow the St. Louis County vital-records page. Confirm eligibility before you mail.
What to bring
Confirm the current ID list on stlouiscountymo.gov.
Where to write or visit
St. Louis County Public Health vital records, as listed on stlouiscountymo.gov. City of St. Louis deaths go to the City Recorder of Deeds (stlouis-mo.gov), a different government. Missouri DHSS is statewide mail.
Notes from the desk
County page this check: $14 for the first certified death copy, $11 for each additional copy of the same record ordered at the same time. The City of St. Louis lists the same dollar amounts on its own page, but it is a different office. This desk takes no cut.
