It depends on which state you were born in, not where you live.Many states have a department that handles the request, while in some states in the Northeast it s actually handled by the town or city where you were born.Below is the CDC website which shows you how to order birth certificates as well as death certificates, marriage licenses, and divorce decrees from each US state and territory. It also includes the costs and any documentation that may be necessary.http://www.cdc.gov/nchs/w2w.htm
