Hi @neffirithion!

It looks like you have what they call an amended birth certificate which shows your adopted parents which was issued at the time of your adoption.

From my search so far... it looks like the original birth certificate is filed in your states 'Vital Record Department'. Some states make it harder to access than others. Check out this link and put in your own state where you live. There should be some information to at least get you started.

I found this interesting article written by Olivia Larson, who was in the same boat as you. She found a loop hole in her state of New York. She figured out that this state issued both the original and amended certificates with the same numbers, and she was able to find hers through the library system. There is also a link to a good birth certificate service on the article too. http://www.articlesbase.com/databases-articles/how-to-search-for-preadoption-birth-certificate-1215181.html

I found the state of Oregon has an easy link online to order your 'pre-adoption birth records'

You can send me a direct message through Mahalo anytime with information of where you're located (state and city) and I can help you further.

I understand how important it is to find your birth parents. I grew up with a step father that signed my birth certificate and didn't find my birth father until I was 21. I only had four years with him until he passed.

The right of every child to a name and nationality, and the responsibility of national governments to achieve this are contained in Articles 7 and 8 in the United Nations Convention on the Rights of the Child: “All children have the right to a legally registered name, and nationality” (CRC Article 7) and "Governments should respect children's right to a name, a nationality and family ties” (CRC Article 8).3

“…it’s a small paper but it actually establishes who you are and gives access to the rights and the privileges, and the obligations, of citizenship”

The U.S. National Center for Health Statistics creates standard forms that are recommended for use by the individual states to document births. However, states are free to create their own forms.21 As a result, neither the appearance nor the information content of birth certificate forms is uniform across states. These forms are completed by the attendant at birth or a hospital administrator, which are then forwarded to a local or state registrar, who stores the record and issues certified copies when requested

Birth certificates in cases of adoptions
In the United States and Canada, when a person is legally adopted, the government will seal the original birth certificate, and will issue a replacement birth certificate noting the information of the adoptive parents, and the adoptive names of the child. In those cases, adopted individuals are not granted access to their own original birth certificates upon request. Laws vary depending on state or province. Some places allow adopted people unrestricted access to their own original birth certificates, whereas in others the certificate is available only if the biological parents have given their permission. Other places do not allow adopted people access to their own original birth certificates under any circumstances.

My first two kids were born in a hospital, and I was forcefully told I *had* to pick a name for the birth certificate immediately. As a result my oldest has a name we would have changed, had we thought a bit further about it.

My last one was born at home (on purpose). I'd had a name picked out for years, and my husband said it was fine. Until she was about 2 days old, when he said "I've changed my mind!"

She was our second daughter, and our first has a classic but unique name that's a hard act to follow without making the sibling sound either plain or of ambiguous gender. I'd found the perfect companion name for it, and he was discarding it?

I told my midwife on her visit that day, because I was worried she had to send in the materials for the birth certificate. She laughed and told me no, I could take all the time I wanted. We'd already started calling the baby the nickname planned, so now we just had to find something it stood for that would match the older sibs' names. It would sound a little strange to have a large age gap and have the youngest one have a much shorter name than her sibs, as if she were an afterthought or an accident, when she was neither.

I finally moseyed on down to the county office about the time she started walking. No problem. And a *much* better experience than trying to pick out a name when I was sleep-deprived and still a bit numb from the epidural!

From what my midwife says, it's pretty common in unusual circumstances not to have the birth certificate issued immediately, or when then child is born at home. The person in charge of that in the hospital just wants to have it taken care of as quickly as possible. My husband's cousin just had her third child last week, and they still haven't picked out a name or gotten the birth certificate.

It is normal to receive the birth certificate days after. My daughter's was sent to me days after in the mail. If you ever want to find your birth mother, Kin solving investigations my be able to help you for a price. If they can't find the person your looking for, you don't have to pay.

I have given it when I was 18 years old.
