"Never ask a lady her age" is one of the oldest social rules in the book. But there are online tools that can help you determine a person's exact age or, at the very least, get you into the ballpark without offending anyone. All you need is a good Internet connection and some basic knowledge about specific information sources on the web. Resources for determining someone's age fall into two main categories: social networking sites (where personal information is often offered or provided) and public records searches.
Log on to a social networking site, such as Facebook or Myspace. If you do not have a profile yet, it is easy---and free---to create one. Follow the instructions on the site for creating a profile. Profiles on social networking sites frequently include information such as birth date or date graduated from school or college. Once you have an active profile on the site, ask to "friend" the person you are interested in. It is perfectly acceptable socially to friend coworkers or casual acquaintances. "Friend" status will give you access to their personal information, often including their age.
Use a public records search site. No registration is required for these sites. A public records search is the most accurate, and the most anonymous, way to search for a person's age. Public records databases draw on publicly available information about a person, such as birth records, voter registration and driver's license records.
Use Intelius to search for a person by name (see References). Enter the name in the search box. If necessary, narrow the search by state. The search results often (but not always) include a person's age, previous address information and possible relatives. Initial results are free, but more detailed information is available for a fee.
Use USA People Search to search for a person by name or phone number (see References). Enter the name of the person you are interested in. The results will frequently (but not always) include a person's age, previous addresses and possible relatives. Results are free, but there is an option to get more detailed information for a fee.
Use Online Searches to search for a person by name or phone number (see References). Choose a state public records database to search (this site allows you to first narrow by location). Enter the name of the person that you are interested in and choose the type of record that you are looking for (you can choose "all"). Results will often include the person's age, previous addresses and possible relatives.
Things You'll Need
