To find someone’s address, start with free public records held by county and state agencies: property tax rolls, voter registration files, court dockets, and business entity filings. If those come up short, the U.S. Postal Service, paid people-search sites, and licensed investigators are the next tiers. Each source captures different people and follows different access rules, so a serious search almost always means checking several. Federal law also limits how you can obtain and use someone’s home address, and those limits shape which methods are open to you.
Start With Free Public Records
Public records are the backbone of any address search. They are free or nearly free, they are searchable by name, and they carry the addresses that people themselves supplied to a government agency.
County Property Records
If the person owns real estate, the county tax assessor’s office is the fastest place to look. Assessor databases are open to the public and typically list the property owner’s name, the property location, and the mailing address on file for tax bills. You need the person’s full name and a reasonable guess about the county. Most counties now offer free online portals; some still require a phone call or a walk-in visit.
The county recorder’s office keeps a separate grantor-grantee index that logs every recorded deed, mortgage, lien, and transfer by the names of the parties. A hit there can point you to a recent purchase or refinance and, from that, to a current address.
Voter Registration Rolls
Nearly every state keeps a public file of registered voters that includes name, residential address, and precinct. Local election boards administer these records, and some jurisdictions offer online search. Access rules vary. Some states let anyone request the file, others limit access to political parties, candidates, or researchers, and a few treat voter addresses as confidential. Where the file is open, voter rolls catch renters who would never turn up in property records.
Court Filings
Civil suits, probate cases, liens, and divorces all require parties to list a residential address. Court clerk offices index these records by name, and most state court systems now offer some form of electronic access. For federal cases, the Public Access to Court Electronic Records (PACER) system covers every federal district and bankruptcy court. PACER charges ten cents per page, but fees are waived if you accumulate $30 or less in a quarter, and most casual users pay nothing.1Public Access to Court Electronic Records.

Marriage license applications are worth checking too. The applicant’s current address is a required field in most jurisdictions, and the records sit with the county clerk or probate court that issued the license.
Business Entity Filings
If the person owns or runs a business, the secretary of state’s office in the state of registration is a strong lead. Every corporation, LLC, and limited partnership must name a registered agent, and the agent’s name and address are part of the public filing. Annual reports in many states also list the addresses of officers, directors, or managing members. The registered agent address is sometimes a commercial service, but officer and member addresses in formation documents are more often personal.
USPS Address Requests
The Postal Service has its own disclosure rules under federal postal regulations rather than the Freedom of Information Act. Under 39 CFR 265.14, USPS treats business and individual change-of-address data very differently.2eCFR. 39 CFR Part 265 – Production or Disclosure of Material or Information A business’s new address is available to anyone who asks. An individual’s new address is released only under narrow exceptions, mostly to government agencies and to people authorized to serve legal process.
Boxholder and Change-of-Address Information for Legal Process
If you have a pending or anticipated lawsuit and need the physical address behind a P.O. Box, or the forwarding address of someone who has moved, you can submit a written request to the local postmaster. The USPS form, titled “Request for Change of Address or Boxholder Information Needed for Service of Legal Process,” asks you to identify the court, list the docket number if one has been assigned, name all known parties, and certify that the information will be used solely for serving legal papers. Submitting false information on that form is a federal crime carrying up to five years in prison, a $10,000 fine, or both.3United States Postal Service. Change of Address or Boxholder Request Format – Process Servers
Ancillary Service Endorsements
A less formal option is to mail a letter to the person’s last known address with “Address Service Requested” printed on the envelope. USPS will forward the mail and return a notice to you with the recipient’s new address. A weighted fee applies to certain mail classes using this endorsement, and for marketing mail the cost can more than double the original postage.4Postal Explorer. Special Address Services (Ancillary Service Endorsements) This only works if the person filed a forwarding order within the past year, the standard forwarding window for most mail classes.
Paid People-Search Sites and Social Media
People-search websites aggregate billions of public records into name-searchable profiles. They pull from property records, voter rolls, and court filings, so they duplicate work you can do yourself, but they save time. Basic results showing a city or a list of possible addresses are usually free. A verified current address in a detailed report runs roughly $10 to $50 per lookup depending on the platform. Accuracy drops quickly for renters, people who move often, and anyone who keeps a light public footprint.
Social media can narrow a search geographically even when a profile does not list a street. A city in a bio, a tagged location on a recent post, or a check-in at a local business helps confirm which region someone lives in. Treat these as leads to verify through a records source, not as proof on their own.
When to Hire a Licensed Investigator
When public records and online searches come up empty, a licensed private investigator can reach databases the public cannot. Skip tracing, the industry term for tracking down a current location, draws on credit header data, utility connection records, and phone service information. None of that is available through free portals, and that access is what you are paying for.
Expect a basic skip trace to cost $300 to $600 as a flat fee. More complex searches involving fieldwork, multiple leads, or a subject who is actively hiding can run $1,500 or more. Hourly investigative rates generally fall between $85 and $150 in most markets. Before you hire, ask whether the quoted price includes verification. A good investigator confirms that the person actually lives at the address, sometimes through a drive-by or a pretext call to a neighbor, rather than handing you a raw database printout.
Give the investigator every identifier you have: full name, date of birth, last known address, phone number, employer. Unique details cut the time and the bill. A common name with nothing else attached can turn a simple trace into a long investigation.
Legal Limits You Need to Know
Locating an address is legal for most purposes, but several federal statutes restrict how you obtain and use the data. Missteps can lead to civil suits, fines, or criminal charges.
Driver’s Privacy Protection Act
The DPPA bars state motor vehicle departments from releasing personal information, including home addresses, from license and registration records unless the requester has a purpose the statute specifically permits.5Office of the Law Revision Counsel. 18 USC 2721 – Prohibition on Release and Use of Certain Personal Information From State Motor Vehicle Records Permissible uses include motor vehicle safety, theft prevention, court proceedings, and insurance claims. Running a plate out of curiosity or for personal reasons is not on the list.6Office of the Law Revision Counsel. 18 USC 2725 – Definitions
Anyone who obtains, discloses, or uses motor vehicle data for an unauthorized purpose is liable to the person whose information was exposed. Minimum recovery is $2,500 in liquidated damages per violation plus attorney’s fees, with punitive damages available for willful or reckless conduct.7Office of the Law Revision Counsel. 18 USC 2724 – Civil Action and Procedures Class actions under the DPPA have produced multi-million-dollar settlements.
Fair Credit Reporting Act
Many people-search sites pull from the same databases that feed credit reports, and the line between a casual lookup and a regulated consumer report depends on how you use the result. Under the FCRA, a consumer report can only go to someone with a permissible purpose such as evaluating a credit application, screening a tenant, making an employment decision, or underwriting insurance.8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports For a regulated purpose, the data source must be FCRA-compliant and you must follow the statute’s notice and adverse-action rules.
Most people-search sites explicitly disclaim FCRA compliance in their terms, which means their reports cannot legally be used for tenant screening, employment background checks, or credit decisions. Using a non-compliant report for a regulated purpose exposes you to statutory damages of $100 to $1,000 per violation for willful noncompliance, plus actual and punitive damages.9Office of the Law Revision Counsel. 15 USC 1681n – Civil Liability for Willful Noncompliance Small landlords and small employers get caught by this more often than you would expect.
Stalking and Harassment
Federal law makes it a crime to use mail, electronic communications, or interstate travel to engage in conduct that places another person in reasonable fear of serious injury or causes substantial emotional distress.10Office of the Law Revision Counsel. 18 USC 2261A – Stalking Finding an address is not itself illegal, but using that address to threaten, harass, surveil, or intimidate can trigger felony charges. State stalking and harassment laws add another layer, and many have been updated to reach online doxxing, where a home address is published to encourage harassment.
When the Person Is in an Address Confidentiality Program
If your search turns up nothing across every source, the person may be enrolled in a state Address Confidentiality Program. Roughly 47 states and the District of Columbia run these programs for domestic violence survivors and other at-risk individuals, providing a substitute mailing address, typically a state government P.O. Box. Participants use the substitute address on voter registrations, property records, court filings, and every other public-facing document. No amount of searching through public records will produce the real residence, and attempting to circumvent the program can carry legal consequences.
If You Still Cannot Find Them
When every method fails, most people looking to serve legal papers get stuck. Courts recognize that some defendants cannot be located through normal channels, and the system has a built-in fallback: service by publication.
Service by publication satisfies the notice requirement of a lawsuit by publishing a legal notice in a newspaper or other approved outlet where the defendant is most likely to see it. Every state allows it, and every state treats it as a last resort. Before a judge approves it, you must demonstrate “due diligence,” meaning a genuine and documented effort to find the person through every reasonably available method. Courts look for evidence that you checked public records, searched online databases, contacted known associates, attempted service at prior addresses, and used the postal channels described above.
The practical requirement is an affidavit of due diligence. This sworn statement details every search you performed, every address you tried, every database you checked, and the dates. Judges read these carefully. A bare-bones filing that says you looked and could not find them will be rejected. Keep a log from the start of your search rather than reconstructing it later.
Federal courts handle service under Rule 4, which allows plaintiffs to follow the service rules of the state where the court sits or where service is being made.11Cornell Law School. Federal Rules of Civil Procedure Rule 4 – Summons In practice, even federal litigation requires you to meet your state’s due diligence standard before the court authorizes alternative service. Some states also permit substituted service, such as leaving papers with a household member or affixing them to the door, when personal delivery has failed but the address itself is known. Check your state’s version of the service-of-process rules before filing.
