State File Number: Where It Appears on a Birth Certificate

A state file number is an identifying number a state vital records office assigns to a record when it is filed. On a birth certificate, it identifies that filed record in the state's files.
What vital record do you need?
Choose your certificate to start your order.
Where it appears
The Illinois Department of Public Health lists the state file number among the items printed on its certified birth certificate, alongside the file date and the date issued. Layouts differ by state and by year of birth, so look for a labeled field such as file number or certificate number, often near the top.
Why you may be asked for it
Forms that look up or request a vital record sometimes ask for the file number to help find the right record. If you do not have it, check the application for the office you are using to see what other details it accepts.
State or local numbers
A record may also carry a local or county number if it was first filed locally. New York shows how this works in practice. The state health department holds birth records for everywhere in the state except New York City, and city records come from the local Registrar of Vital Statistics. Which number is the state number depends on which office registered the record.
