The Missouri Bureau of Vital Records serves as a state-level resource for O'Fallon death certificate requests when local offices cannot help.
The library also has access to local newspaper archives on microfilm.

How to Request O'Fallon Death Records
When you request a death certificate for someone who died in O'Fallon, you can do it in person at the county health office, by mail, or through VitalChek online. In-person requests are the fastest. Bring your photo ID and be ready to show how you are related to the person on the certificate. Mail requests take longer but work the same way. Online orders through VitalChek carry an extra handling fee on top of the base cost. Under RSMo 193.145, all deaths must be filed with the local registrar, so deaths in O'Fallon should appear in the state system from 1910 forward.
If you are looking for an O'Fallon obituary rather than a death certificate, the county library and newspaper archives are better places to start. Obituaries carry more personal details than certificates do. They often list family members, church membership, career, and funeral home information. Death certificates, on the other hand, give you the official cause and date of death, the place of burial, and the attending physician's name. Both types of records work together when you are building a full picture of a person's life and death in O'Fallon.
Public Access to O'Fallon Obituary Data
Missouri's Sunshine Law under RSMo Chapter 610 keeps most public records open for review. Vital records have some limits. Under RSMo 193.245, sharing vital record data outside what the law allows is not permitted. Recent death certificates need proof of family ties or legal authority. But death records over 50 years old are open to anyone.
For O'Fallon obituary research, that means recent death certificates are restricted. But the State Archives databases, pre-1910 records, newspaper obituary collections, and cemetery records are all available to the general public. Genealogists working on behalf of a family member can also request copies of more recent death certificates under RSMo 193.255.
Note: Some St. Charles County circuit court records are on microfilm and may contain death-related legal filings for the O'Fallon area.
