1. Start with Property Records
If you have a last-known street address, the fastest first step is the county assessor or recorder. Most U.S. counties let you search property ownership by name or address, often free. Owner history lets you see when someone moved or sold.
Open the SearchSystems county directory and click your state, then your county: see Guide to Finding People with Public Records or Harris County, Texas for examples. Property data also exists in many city / town offices in Virginia, New England, and other compact-government states.
2. Recorded Documents (Deeds, Liens, UCCs)
The county recorder / register of deeds holds far more than just deeds. Expect mortgages, liens, satisfactions, military discharges (DD-214), bonds, marriage licenses, divorce decrees, child-support records, DBAs, financing statements (UCCs), trusts, leases, and wills.
Try Maricopa County, AZ (recorder.maricopa.gov) or Cuyahoga County, OH (cuyahogacounty.us). Each county exposes different document classes — compare two and you’ll see how rich a recorder index can be.
Browse the SearchSystems recorded documents directory by state for direct links.
3. Voter Registration
Many counties — and some entire states — publish a free voter-lookup tool. You confirm a registered name, date of birth on file, and an address. It will not return phone numbers, but it strongly verifies that a person lives where you think they do.
Find your state’s tool in our voter records directory.
4. Professional License Lookups
Doctors, nurses, contractors, real-estate agents, attorneys, accountants, security guards, cosmetologists, even auctioneers — all licensed at the state level. State portals let you verify the active address on file, license status, and any disciplinary action.
Browse California licenses, Florida licenses, or any other state from the SearchSystems directory.
5. Court & Criminal Records
Civil and criminal cases include names, addresses, and sometimes dates of birth. Even if you can’t see full documents, the case index alone may confirm a person’s current city. PACER covers federal courts (per-page fee); each state has its own portal — check the SearchSystems court records page for your state.
6. Vital Records (Birth, Death, Marriage)
Vital records establish the basic facts of a person’s life. Most modern state offices restrict open access for privacy, but historical indexes (typically anything older than ~50 years for births, 25 years for deaths) are often public and free. See your state on the vital records directory.
For research older than 1940, also check the FamilySearch wiki for your state — it’s free.
7. Free Phone & Address Lookups
Free directory assistance is gone, but several legitimate free indexes still work. The Federal Communications Commission (FCC) publishes its licensee database (call signs and addresses of radio operators and broadcasters): see FCC databases. State and federal employees often appear in public directories at USA.gov.
9. Reverse Lookups
If you have a phone number or address but no name, start with the FCC (for landlines) and county recorder (for addresses). Local newspaper obituaries on Legacy.com and free public-library databases at FamilySearch can fill gaps.
Legal & Ethical Limits
The federal Fair Credit Reporting Act (FCRA) bars using public records to make employment, credit, insurance, or housing decisions unless you go through a regulated Consumer Reporting Agency. State stalking, harassment, and identity-theft laws apply too. Use public records to verify identity and find lost relatives — not to harass.

8. Social Media & Open Web
Public posts on LinkedIn, Facebook, X, and Instagram are still the fastest way to locate someone today. Combine the person’s name with a city, employer, or alma mater in Google. Reverse-image search of a profile photo on Google Images can also surface other handles.
