Vital records include birth certificates, death certificates, marriage licenses, divorce decrees, naturalization records, and adoption records.
The federal government does not distribute certificates, files, or indexes with identifying information for vital records. There are databases that link to multiple state websites that have this information, but to use them you must know the state or territory in which the event occurred. Note that access to these documents is often restricted to immediate family members, and obtaining the records usually requires payment of a fee.
The information, and sometimes a copy of the document, may be also be available through a genealogy website such as Ancestry.com, AncestryLibrary, or FamilySearch. Note that these sites may require a paid subscription or a fee for downloading a document.
