Dubbo residents who were adopted can now have both their birth and adopted families' names on their birth certificates.
New laws came into effect this week allowing integrated birth certificates (IBCs) to be issued to adopted people for the first time in NSW's history.
"This marks the beginning of a new era in the recognition of adopted people's history before and after adoption," Attorney General Mark Speakman said.
Minister for Families, Communities and Disability Services Gareth Ward said the government had listened to calls for reform.
"IBCs will enable adopted people to have greater control over their own story, history and identity, and we're proud to take this significant step forward," he said.
There will be no additional cost for an IBC at the time of adoption.
A person who is issued a post-adoptive birth certificate with an IBC will only be required to pay the fee for one certificate.
IBCs are also available for adoptions that occurred before November 16.
