To find someone’s past addresses, start with free county public records — property and tax rolls, voter registration files, and court dockets — then fill gaps with a paid people-search report or, if the trail goes cold, a licensed private investigator. Searching for an address in public records is legal in every state. What is not always legal is where you pull the record from (motor vehicle files and postal forwarding data are restricted) or what you do with the address once you have it.
Gather These Details First
The more you know before you search, the fewer false matches you’ll wade through. A full legal name is the starting point, but maiden names, former married names, and common nicknames matter just as much, because records are indexed under whatever name the person used at the time. A date of birth or approximate age is the single most useful disambiguator for a common name.
A last known address or phone number gives you a geographic anchor. Most public-records databases are organized by county, so even knowing the right state cuts your search from thousands of jurisdictions down to a handful. Names of relatives or former spouses can open side doors: if you can locate a relative’s property record or court filing, the person you’re looking for may appear in the same document.
Property and Tax Records
County assessor and recorder offices hold two overlapping sets of records that are among the easiest free sources for past addresses. The assessor tracks property ownership for tax purposes and lists the owner’s name, the property address, and usually a separate mailing address. The recorder holds deeds, mortgages, and liens showing every transfer of ownership. Both are public in every state, and many counties publish searchable databases online at no charge.
Because these records go back decades, they can reveal a chain of addresses. A person who sold a home in one county may have bought in another, and following the deed trail fills in gaps other sources miss. Start with the county where you believe the person last lived and work backward. If the county doesn’t offer online access, you can request records by mail or visit the office in person. Copy fees for paper documents typically run a few dollars per page.
Voter Registration Records
Voter registration files contain a person’s name, residential address, date of birth, and often a mailing address and party affiliation. State forms also collect identifiers like a driver’s license number or partial Social Security number, but those fields are almost always redacted before public release.1U.S. Election Assistance Commission. Voter Lists: Registration, Confidentiality, and Voter List Maintenance
Access rules differ by state. Some states release the voter file to anyone who requests it; others restrict access to political parties, candidates, journalists, or government agencies, and many prohibit commercial use of the data. You may be able to inspect the rolls at a local election office or request a copy for a fee, but the rules where the person registered will control what you can get and what you can do with it. If the person has moved between states and re-registered, earlier registrations can confirm past addresses even after the current record has been updated.
Court Records
Civil lawsuits, divorce filings, small-claims actions, and criminal cases all generate documents that list the parties’ addresses at the time of filing. Many state court systems offer online portals where you can search by party name across an entire state. When online searching isn’t available, the clerk’s office at the courthouse will let you look through case files. Viewing records in person is usually free; copies and electronic access may carry per-page or per-search fees.
Not every court file is open. Adoption and juvenile proceedings are sealed in virtually every jurisdiction, and judges can seal other records for privacy or safety reasons. Bankruptcy filings are a particularly useful subset because they’re federal, searchable through the PACER system, and typically list every address the debtor has used in recent years.
People-Search Websites
Sites like Whitepages, Spokeo, and BeenVerified scrape and aggregate public records, social media profiles, data-broker files, and other commercial datasets into a single profile. They surface past addresses that would take hours to find through individual county offices, and basic searches showing a name and city are often free. Detailed reports with a full address history, associated phone numbers, and known relatives typically cost between a few dollars for a one-time lookup and $20 to $30 per month for a subscription.
The tradeoff is accuracy. These databases pull from sources that update on different schedules, so you’ll sometimes see outdated addresses shown as current, or two different people’s records merged into one profile. Treat any result as a lead that needs verification through an official record. Cross-referencing against property records or voter registration data is the fastest way to check.
Social media and professional networking profiles can also reveal location history. Many people list current and past cities on their profiles, and geotagged posts can fill in timeline gaps. The information is only as good as the person’s privacy settings allow, but it’s worth a quick search before paying for a report.
Sources You Generally Cannot Use
Two sources that seem like they’d be obvious address lookups are off-limits to the general public.
DMV Records and the DPPA
State departments of motor vehicles hold current and historical addresses tied to driver’s licenses and vehicle registrations, but the federal Driver’s Privacy Protection Act tightly restricts who can access that data. The DPPA authorizes release only for specific purposes, including government functions, court proceedings, insurance claims, vehicle safety and recall work, and use by licensed private investigators.2Office of the Law Revision Counsel. 18 U.S. Code 2721 – Prohibition on Release and Use of Certain Personal Information From State Motor Vehicle Records
Personal curiosity is not on that list. A private citizen generally cannot request another person’s address from the DMV unless the request fits one of the DPPA’s authorized categories, such as serving legal process or verifying information submitted in a business transaction. Violating the DPPA exposes you to a civil lawsuit by the person whose records were improperly obtained, with a minimum of $2,500 in liquidated damages per violation plus potential punitive damages and attorney’s fees.3Office of the Law Revision Counsel. 18 U.S. Code 2724 – Civil Action
USPS Change-of-Address Records
When someone files a change of address with the Postal Service, that information goes into a restricted database. Ordinary individuals cannot request another person’s forwarding address just by asking. The USPS will disclose change-of-address information only for the service of legal process in actual or anticipated litigation, and the requester must provide case details, the court involved, and the capacity in which the person is being served.4United States Postal Service. Change of Address or Boxholder Request Format – Process Servers
There is no fee for the request itself, but submitting false information to obtain an address carries criminal penalties of up to $10,000 in fines or five years’ imprisonment under 18 U.S.C. § 1001.4United States Postal Service. Change of Address or Boxholder Request Format – Process Servers If you’re involved in a lawsuit and need to locate a party for service, this is a legitimate and free avenue. Otherwise, the USPS is not available to the general public for address searches.
When to Hire a Licensed Private Investigator
If your own searching hits a dead end, a licensed private investigator has access to professional databases the public cannot use. Tools like TLOxp, LexisNexis Accurint, and IRB Search aggregate billions of records from credit headers, utility connections, and public filings into products designed for skip tracing. They often return a complete address history within minutes, including addresses that never appear in free public-records searches.
PIs also have broader legal authority. The DPPA explicitly allows licensed investigators to access motor vehicle records for any purpose the statute permits.2Office of the Law Revision Counsel. 18 U.S. Code 2721 – Prohibition on Release and Use of Certain Personal Information From State Motor Vehicle Records That access alone can justify the cost when DMV records are the missing piece. Expect a flat fee in the range of a few hundred dollars for a straightforward skip trace, or hourly rates of $50 to $150 or more for complex searches that require fieldwork. Licensing requirements vary by state, so verify the investigator holds a current license in the jurisdiction where the search will take place.
What You Can Legally Do With an Address
Searching for a publicly available address is legal. What you do with it is where the law gets serious.
The Fair Credit Reporting Act
Consumer reports assembled by credit bureaus and background-check companies contain detailed address histories, but the FCRA restricts who can pull those reports and why. A consumer reporting agency can furnish a report only when the requester has a recognized “permissible purpose,” such as evaluating a credit application, screening a job candidate (with the applicant’s written consent), underwriting insurance, enforcing a child support order, or reviewing an existing account.5Office of the Law Revision Counsel. 15 U.S. Code 1681b – Permissible Purposes of Consumer Reports Personal curiosity, debt collection by someone who isn’t the creditor, and general background snooping are not permissible purposes. Obtaining a consumer report without one is a federal violation.
Anti-Stalking and Harassment Laws
Federal law makes it a crime to use the mail, internet, or any interstate communications tool to engage in conduct that places someone in reasonable fear of serious harm or causes substantial emotional distress.6Office of the Law Revision Counsel. 18 U.S. Code 2261A – Stalking Every state has its own stalking and harassment statutes on top of that. Using a legally obtained address to show up uninvited, send threatening communications, or monitor someone’s movements can turn a lawful search into a criminal act.
A Note on the Privacy Act
The Privacy Act of 1974 is often invoked in the wrong context. It governs how federal executive-branch agencies collect, store, and share personal information in their own record systems. It does not restrict private citizens, businesses, or state governments from searching for or sharing address information.7U.S. Department of Justice. Privacy Act of 1974 It has no bearing on your ability to search county property records or voter rolls.
