Final answer:
To change a name in the registration system, typically a birth certificate, passport, or driver's license is used. These documents validate one's identity and reflect legal name changes. Requirements can vary by state, and local laws should be consulted.
Step-by-step explanation:
The types of documentation that may be used to make a name change in the registration system vary depending on state and local regulations. Generally, official documents such as a birth certificate, passport, and driver's license are used to validate one's identity for a name change. Specifically, a birth certificate serves as a foundational identity document that can validate a person's legal name from birth. A passport is a federally issued document that not only validates identity but also nationality, and it can reflect changes such as marriage or legal name changes. A driver's license, issued by state governments, commonly reflects one's current legal name and residence.
Keep in mind that different states may have unique requirements for documentation needed to support a name change. In some cases, a social security card might also be required to update employment and tax records. States may also vary in their policies related to gender identity changes on identity documents. It's important to check the specific requirements of your jurisdiction before initiating the process.
