Birth certificates are among the most common sources of birthday information. These vital records are created when a person is born and filed with the state or county vital records office. Most states maintain centralized databases of birth certificates, though the specific procedures and accessibility vary by state. Some states allow online searches through their vital records websites, while others require requests by mail or in person.
Court records often contain birthday information. When someone appears in court for any reason—civil disputes, criminal matters, or family law cases—their date of birth typically appears in the official court documents. Many county courts now offer online access to case files and docket information through public database systems. These records are usually searchable by name and case number.
Property records frequently include birthday information. When someone buys property or refinances a mortgage, their birth date often appears in the recorded deed or mortgage documents. County assessor's offices and recorder's offices maintain these records, and many now provide online search tools. Real estate transaction databases operated by private companies also compile this publicly recorded information.
Voter registration records contain birthday information in most states. When someone registers to vote, their date of birth becomes part of the voter rolls. State election offices maintain these records, and many provide public search tools online. The level of detail available varies—some states show full birthdates, while others may only display birth year or age ranges.
Practical takeaway: Before searching for birthday information, identify which type of record is most likely to contain it. If you're looking for someone's birthday for family history purposes, start with vital records. For legal matters, court records may be most relevant. For property-related information, begin with county assessor databases.
Each state maintains its own vital records office that oversees birth certificates and related documents.

Most state vital records websites follow a similar general structure. You'll typically find a search function where you can enter a person's name and other identifying information. Some states require additional details like the approximate year of birth or parents' names to narrow down search results. The search results usually show basic information like the full name, date of birth, and sometimes the county where the birth was registered.
Important variations exist between states. Some states offer completely free public searches of their vital records databases. Others charge a small fee for searches, usually between $5 and $15. A few states restrict who can view birth records—for example, some only allow direct family members or people with a documented legal interest to view full details. Still other states keep detailed records private and only provide limited information such as confirmation that a record exists.
To search a state vital records website, you'll generally need to: Navigate to the state's vital records office website, usually found through the state health department; Look for a "search records" or "public records search" link; Enter the person's name and any other requested information; Review the search results, which may display birth date information; and optionally, order an official certified copy if needed, which typically requires payment and additional verification.
Some states use third-party vendors to manage their online searches. VitalChek and iGov are common platforms that operate vital records search systems for multiple states. These platforms standardize the search process but may charge convenience fees in addition to the state's record fees. Understanding which platform your target state uses helps streamline the search.
Practical takeaway: Start by identifying which state's vital records office maintains the record you're seeking. Visit that specific state's health department website and look for their vital records search tool. Bookmark the direct link for future reference, as these databases can be valuable resources for genealogy and personal research.

Private companies like Zillow, Trulia, and county-specific websites aggregate and republish property record information.

However, the information on private platforms is typically less current than official county records.
