Where to request
Birth certificates for people born in Nassau County are issued by the New York State Department of Health, Vital Records, the central state agency in New York. The county itself does not maintain a separate registry of certified birth certificates; all requests are routed through the state office.
If the birth occurred before statewide registration began in 1880, the state office will refer you to the Nassau County Clerk or to the New York State Archives, where pre-registration records (when they exist) are typically held.

How to order
By mail
Download the application form from the official New York office page at https://www.health.ny.gov/vital_records/ (for state-issued records) or from the Nassau County website (for county-issued marriage and divorce records). Include a clear photocopy of an acceptable photo ID and a money order for the fee.
In person
For state-issued records, walk-in service is available at the central office in the state capital — see the address in the table above. For county-issued marriage and divorce records, walk-in service is available at the Nassau County courthouse during regular business hours; bring photo ID and the fee in cash, money order, or card.
Online
New York's state office partners with VitalChek for expedited online ordering of birth and death certificates. Many county clerks now also offer online ordering for marriage records through their own portals or through VitalChek; check the Nassau County Clerk's website for the current option.
What you'll need
- Full legal name on the certificate, including any maiden or alternative names.
- Date of the event (or a date range, for older or uncertain records).
- Place of the event — at minimum, the city or township within Nassau County.
- For births: parents' full names, including mother's maiden name.
- For deaths: spouse's name (if any) and approximate age at death.
- For marriages: both spouses' full legal names at the time of marriage.
- For divorces: case number if known, otherwise both parties' full legal names and the year of the divorce.
- A clear copy of acceptable photo identification.
- A money order or cashier's check for the fee, made payable as instructed by the office.

Common pitfalls
The most common reasons a request to Nassau County or to the New York State Department of Health, Vital Records is delayed:
- Wrong office. Sending a marriage record request to the state office in a county-issued state, or vice versa, simply gets the application returned weeks later.
- Insufficient identification. Photocopies must be clear, in color where possible, and unexpired.
- Wrong fee. Personal checks are sometimes refused; out-of-state checks even more often.
- Restricted record. If you are not the registrant or an immediate family member, expect the office to require additional documentation of your eligibility.
