Locate the vital records website of the state where the birth occurred. The National Center for Health Statistics (see Resources) provides links to the websites of each state's vital records office. While some states process their own online replacement birth certificate orders, others use private records processing companies, such as VitalChek.

Find your state's requirements for requesting a replacement birth certificate. Most states require the full name of the person on the certificate, the date of birth, the full names of the mother and father, the requester's relationship to the person named on the certificate, and the city and county where the birth took place. Complete the online form on the website of the records processing company or state vital records office.

Document your identity. States require proof of the requester's identity in the form of a state-issued driver's license, a passport or other official document. Scan the identity documentation on a photo scanner to create a computer file to include with your online form.

Send payment to the vital records office or records processing company. The private company will add an additional amount to the fee required by the state or local vital records office.
