Find a missing person

Our missing person cases have involved finding lost children, biological parents for the adopted, old friends, lost loves, and co-workers.

The circumstances that separate friends and family- such as adoption, death, war, marriage, job promotion, travel and illness-can leave you feeling anxious and unresolved. Lingering questions arise that may go unanswered for months... or even a lifetime: Who are my real parents? What happened to my best friend from school? Does anyone know where she moved after her husband died? Is he still in the service? Do they know I have AIDS?

Whether the reasons are personal, medical or financial, you've made the decision to find someone important to you. You thought it would be hard but now the search looks even more daunting. Don't worry, we're here to help.

Who benefits from a search?


In the early 1960s, Joanne was young, pregnant and no longer involved with the baby's father, a married man who was unwilling to help. Reared in a strict Catholic family, Joanne didn't see abortion as an option but knew she wasn't able to be a proper mother. With the help of her church organization, Joanne made a difficult choice and gave up her days-old daughter for adoption. The adoptive couple named the baby Erika. When Erika was old enough to understand, they told her how she came into their family. Even though Erika had a good life-she felt loved and cared for-she wondered about what could have been. Mostly,' she wondered about her biological parents: what they looked like, where they came from, why they gave her up. As the years passed, Erika became a mother herself, and the desire to know about her heritage grew stronger. Would she ever be able to pass on information about her family's history? Was there anything in her birth parents' medical background that she should know about? Were they still alive?

Her birth mother has questions as well. All her life, Joanne had hoped her daughter was happy, and now she wants to know for sure. She hopes to reaffirm that she made the right decision. She also needs to communicate how she truly feels, to seek understanding and forgiveness, and to develop a relationship. Both Erika and Joanne would find comfort in knowing more.

Family Reunions

Marshall's parents divorced when he was just an infant. He lived with his mother while his father took custody of his older brother, Rick. When Marshall's mother remarried, he lost contact with his father and brother. He doesn't intend to leave it that way; Marshall is set on locating them and finally connecting with his big brother and his dad.

Reunited Friendships

It's been years since high school and Sacha still thinks about her best friend, Lindsey. The thoughts are pleasant because they were once inseparable. The "dynamic duo" went to parties and football games, smoked their first cigs behind the Roller Rink, failed Algebra and passed notes about their secret crushes. But they lost touch after that great senior year. Sacha didn't attend her five- or ten-year reunions and doesn't know whether Lindsey is married, has changed her name or has moved. Is a search hopeless? No.

Fractured Friendships

Frank's girlfriend left him for his best friend, Greg. Frank and Greg haven't spoken to each other for five years. Frank wants one more conversation with Greg to let him know how blindsided he was by his friend's betrayal. Call it closure. Friendships that end abruptly or prematurely may need resolution.

Financial Responsibility

Heidi and her three children have had money trouble ever since Heidi's ex-husband remarried and moved to another state. Child support and spousal support payments haven't reached her mailbox for months. He needs to be found before legal papers can be served requiring him to make payments.

Moral Responsibility

If you're diagnosed with a contagious disease, such as herpes or AIDS, you need to alert past sexual partners. Making that decision is clearly the right thing to do, but following through may be difficult since couples often don't stay in touch after they've broken up. Finding a former partner could be hard, but certainly not impossible.

How Do I Find Someone?

Where to begin? That depends on the information you already have and what you need to find out. The necessary steps will be fewer if you have the person's name and you're just looking for a current address or telephone number. Names may be unknown for someone looking for an adopted child or for birth parents. In these cases, your search will take more time while you contact everyone you think may have a piece of the puzzle-a relative, former neighbor, clergy, lawyer or caseworker. Once you have a name, you can use these easily accessible sources:

Search Engines

Basic web searches may guide you to the missing person's address and telephone number. The top 4 search engines by usage are Google, Yahoo, Bing, and Ask. By using different search engines, you can obtain different results, since each engine has different data sets and ways of returning results. When performing searches, remember to put your search phrase in quotation marks (eg. "thomas martin") to improve the relevance of your results.

When it comes to finding people, a very useful and less well known search engine is Zabasearch. This web site searches for and lists different types of information for United States citizens, including addresses (both current and past), phone numbers, birth years, and more. While the privacy concerns surrounding Zabasearch are controversial, at the end of the day, it really works.

Another particularly resourceful search engine specifically for people searching is, an online directory of the telephone numbers and addresses of 106 million Americans.

Social Networking Web Sites

These days, most people under the age of 30 have some sort of profile on a social network. Popular social networking sites such as Facebook, Linkedin, and Google+ offer search facilities of their pages by name, zip code, and email address, although using them typically requires registration. Don't forget older social media channels liek MySpace, as old, abandoned profiles may still be useful.

If you'd like to try searches at a number of social networking sites, the Wikipedia maintains this list of social networking Web sites.

Other Web sites

“Public servants at the county, state and federal level can provide you with lists of public records at all levels.”

Other sites may aid in your search. Here are a number of addresses with brief descriptions of the information they offer:

  • The Ultimates - An invaluable site that assists with roughly 85% of our lookups. This site lets you search multiple people-search resources in one spot.
  • Welfare/Whereabouts Services Abroad - a service provided by the Department of State and U.S. embassies and consulates to help locate U.S. citizens overseas when there is an emergency or questions regarding the person's welfare.
  • World Wide Internet Directory - a directory listing people search services worldwide.
  • The Federal Parent Locator Service is the section of the Federal Office of Child Support Enforcement's web site lists information, systems and agencies available to those looking to locate pariticpants in child support cases.
  • Social Security Death Index
  • RootsWeb Genealogical Data Cooperative Page - Tracks surnames.
  • The U.S. GenWeb project - A volunteer effort that offers advice on how to find basic genealogical data, such as local churches, cemeteries, and court, land and property records. Each state has its own Web page that lists phone numbers of local archives, genealogical societies and libraries.
  • National Archives - Posts details on its records and how to access them.
  • - Millions of vital records useful for research in genealogy, legal, family history, etc.


A true-life story

On February 4, 1997 I received the following letter at my office:

I am trying to locate my former high school sweetheart, John Hinto, of Burbank, California. We met at the end of our sophomore year at a local high school and dated for a year-and-a-half. Our parents felt it was not in our best interests to continue seeing each other because of our religious differences: I am Catholic and John is Jewish.

Upon graduation in 1960, I married another man and John went on to college. At our twentieth high school reunion in 1980, I heard that he had married a Catholic girl, divorced, lived in Santa Rosa, and was a police officer. John's dad passed away and his mother remarried and moved to Ohio. After John divorced he also moved to Ohio and became a stockbroker. John had a younger brother named of Tom; his father's name was Ralph. I remember his mom's name. His father had a deli business and was an investor in mutual funds. John has a cousin, Terry Miles (maiden name), who also graduated from our high school.

Through the years, I have often thought of John and many times wondered how differently our lives might have turned out had we been left to make our own decisions. I would like to talk with him and see how he's doing. As you may have gathered, I am now single.

If you are able to locate or come up with any leads or information, please contact me.

We immediately searched on our in-house computer system for John Hinto. We learned that there were approximately 70 possibilities based on this name. His graduation date of 1960 was the primary clue we used to track down Mr. Hinto, who was living in Northern California. Mr. Hinto was personally contacted by one of our investigators and was most excited to meet our client. Mr. Hinto traveled to Southern California to have dinner with our client on Valentine's Day 1997. So far, so good.

Directory Assistance

Sure, this sounds obvious, but it happens to be the most overlooked source. If you know the area where the person was last living, call local directory assistance at (area code) 555-1212. People often have walked into our offices with their checkbooks out, ready to spend hundreds of dollars to find someone who is listed in the White Pages.


Right, that familiar old building on the corner. The library reference section stocks crisscross directories that contain phone numbers and addresses. With on-line services or other published indexes, by using the phone number you can find the address, or vice versa. Many libraries also have an extensive collection of Yellow Pages covering areas in the United States. These can help you find a private investigator or public records company to continue your search (see Chapter Sixteen for guidelines on hiring a private Investigator).

Public Records

You may have information that can indirectly lead you to a publicly recorded event, such as a birth, marriage or death. Or perhaps you know of another legal process that took place that may list valuable information in its filings, including the person's or his or her attorney's address and phone number. Many public servants work at the county, state and federal level and can provide you with lists of public records at all levels that may help with your search. The most reliable listings are:

  • Derogatory Financial Records: Records you can search include Bankruptcy Information, Notices of Default, Judgment Index, and Tax Lien Information (claims on property to secure a debt). These will include all such filings with names and addresses and may even provide a Social Security number.
  • Fictitious Business Name Index: Lists business owners' names and addresses who are "Doing Business As" a company name.
  • Misdemeanor Criminal Records: Lists names of people charged with misdemeanors.
  • Real Estate and Tax Information: Lists property owned by an individual or business.
  • Registered Voter Information: Lists names and addresses of registered voters. Records and the information they contain will vary from state to state. Sometimes, a telephone number, Social Security number and a date of birth are also included. This information is only accessible to the public in Arkansas, Colorado, Connecticut, Delaware, Georgia, Louisiana, Maryland, Maine, Michigan, Montana, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Rhode Island, South Carolina and Texas.
  • Superior Court Civil Records: Filings of civil cases, including lawsuits and divorce proceedings. Records are listed separately by defendants and plaintiffs. Plaintiffs' names are easier to look up because there is usually only one plaintiff, while there may be more than one defendant and only the first person's name is listed alphabetically.
  • Superior Court Criminal Records: Lists names of people charged with felonies.

State Records

Each state issues licenses for various occupations, professions and trades, such as accountants, architects, cosmetologists, nurses, private investigators, psychologists and tax preparers. If you know the person has or may have a professional license to perform a service, you may find information this way. State records also include:

  • Bankruptcy Records
  • Birth Records
  • Corporate Records
  • Death Records
  • Divorce Files
  • Marriage Licenses
  • Uniform Commercial Code Filings: These filings are recorded when one party, usually a business, secures loaned collateral or assets.
  • Workers' Compensation Records

Federal Records

This is not our first choice because it's a tedious effort, but if you're patient and have time to spare, federal records can be accessed using the Freedom of Information Act or by writing directly to specific federal agencies for information. Replies can take up to six months, but the service is free. Here's a sampling of listings:

  • Federal Aviation Administration: Pilots' licenses.
  • Interstate Commerce Commission Records
  • Military Records
  • U.S. Post Office: To obtain business owners' names and addresses.
  • U.S. Tax Court: IRS filings.

The Department of Motor Vehicles

The folks here don't just tell you to "smile" and then take a lousy picture for your driver's license. You may be able to contact the DMV and request a name search to get a home address. The person's date or year of birth will speed up the process. Keep in mind, however, that public access rules and regulations vary with each state; some states will provide address information-as well as date of birth and a complete description-while other states will not give out any information.

Dead Ends

If your detective work hits a roadblock or if you run out of time to devote to the search, you may consider hiring a private investigator. Or if the person you're looking for has an unusual name or if you have his or her Social Security number or the last-known address, a private investigator's database may save you time and effort from the start. An investigator can access the Main Name Index-a-listing of names in the United States. This is a quick search if the person has an unusual name. An investigator can also call up an address on the Address Update Index-the top half of a credit report. If you know the person's Social Security number, it's a slam dunk. The investigator calls up the Social Security Index ranges. For any of these services, you may pay a search firm from $100 to $1000, a justifiable fee if it expedites finding a lost loved one, alumnus, you name it.

Our national company, which can be reached by dialing 1-888-US-UNITE, accesses our private database-the world's largest-and offers a fast, accurate, customized search with guaranteed results. Our staff will provide you with the most current information on any individual.


Once you've found your missing person, then what? If the situation is delicate, it may be wise to have an objective, professional party make the first step. He or she can explain your situation and express your desire to make contact. In most cases we've handled, the people contacted were surprised, apprehensive and nervous. But far more often than not, they agreed to meet the person looking for them.
