Things You'll Need
Contact the office of vital statistics in the state in which the birth occurred and ask where the records are located. Many states maintain records of live births in more than one location. As a general rule, recent records are maintained by local municipalities or county at offices, and older records reside at the state level.
Contact the appropriate office. Ask for guidance in requesting a duplicate birth certificate. You will be required to provide identification and to pay a small replacement fee.
Ask about the forms of identification you will need. Some states require your driver's license number (or a photocopy of the photo ID) and issuing state. (See Resources for individual state requirements.) You will also be asked to state your relationship to the person whose birth certificate you seek and the reason for the
request. Generally you are limited to requesting the birth certificate of yourself, your children or spouse, siblings or parents. You may also be able to obtain a certified copy of deceased ancestors for genealogical purposes.
Write a letter to the appropriate office stating your request. Include as much information as you have about the name, date and place of birth of the person whose birth certificate you seek. Include nicknames and variant spellings. This is especially important for genealogy searches dealing with older records, as documentation was often hand-written and errors in spelling were fairly common.
Include a check for the appropriate fee and all forms of requested identification. Check that you have included all necessary documents and mail to the appropriate office. You should receive a copy of the birth certificate within two weeks, although time varies from state to state.
