I hope I am giving you appropriate advice. Everything I know about an official birth certificate versus a live birth certificate is that only the former can be used for official governmental business, ie., acquiring a passport. For example, let's say you want your child to have dual citizenship (I hope you do) and you send the required information to the Canadian Consulate that serves your area. Part of the required information is an official birth certificate (long form) you would have to send to the Canadian Consulate. Yes, you should go to your municipal office or just call them to have them send you the long form birth certificate. This can be done by mail.
Here is a better explanation of the two documents and the process of how an official birth certificate is created from the live birth certificate. Best
A baby’s birth certificate is created using a form called the U.S. Standard Certificate of Live Birth. This form simply states that a child was born in the United States and was considered medically alive at birth.
The certificate is usually filled out by the child’s parents or the staff members at the hospital or facility where the child was born. Then, it must be submitted, either by mail or electronically, to the state, county, or city office responsible for creating and maintaining birth records in that state. The Certificate of Life Birth form includes information on the:
Baby’s full name
Baby’s place, date, and time of birth
Baby’s gender, race, weight, and any health conditions
Parents’ full names
Hospital or birthing facility where the baby was born
Attending doctors or midwives
The person completing the birth record
The baby’s parents, the facility staff, or the attending doctors or midwives can submit the form to the state. The appropriate agency will process the Certificate of Live Birth, then the vital records office for the state will issue a new U.S. birth certificate for the child.
Birth Certificate vs. Certificate of Live Birth
While a Certificate of Live Birth is used to create a birth certificate, they are not the same documents. The Certificate of Live Birth is the application, while the birth certificate is the actual vital record created using the information provided on the form.
A person’s original birth certificate is always kept on file at the vital records office where it was created. The vital records office will use the original to make a certified copy of the birth certificate when requested. Certified or long-form copies of a birth certificate will contain information on the individual’s:
Full, legal name
Place and date of birth
Gender at birth
Parents’ names
A certified birth certificate copy will include certain identifying features, including a raised, multicolored, or embossed state seal, the registrar’s signature, and the date of issuance. Only certified copies can be used as proof of identity, age, and citizenship.
