The quickest way to find someone’s address is to start with free public records — county property and tax rolls, voter registration files, and court filings — then move to paid people-search sites, the U.S. Postal Service, or a licensed investigator if those come up empty. Which route fits depends on why you need the address and how much you already know about the person. Every method has legal limits, and a few of them carry federal penalties if you cross the line, so the “how” matters as much as the “where.”
Free Public Records to Search First
County Property and Tax Records
County tax assessor offices maintain searchable databases tied to property ownership. Type a name into one of these databases and you can pull up the property that person owns, its assessed value, and the mailing address where the county sends tax bills. Most counties offer this search online for free. The mailing address on file often matches the owner’s home address, though some owners use a separate mailing address for privacy or because they own rental property.
Deed records kept by the county recorder are another angle. Every time someone buys, sells, or refinances real property, the transaction is recorded with the parties’ names and addresses. These records are public in every state, though some counties charge a small fee for online access or physical copies. If the person has bought or sold property in the last several years, a deed search can confirm where they were living at the time.
Voter Registration Files
Voter registration records typically include a registrant’s name, home address, and party affiliation. All 50 states and the District of Columbia allow some form of access to these records, though who can request them and what information is disclosed varies significantly.1National Conference of State Legislatures. Access To and Use Of Voter Registration Lists Some states make the full file available to any member of the public; others restrict access to political parties, campaigns, journalists, or researchers. A handful of states redact home addresses from public copies. Where access is open, voter rolls are one of the fastest free ways to find a current residential address for a registered voter.
Court Filings
Civil and criminal case filings routinely include the addresses of plaintiffs, defendants, and witnesses. Complaints, answers, and affidavits of service all list a residential address for the parties at the time of filing. Many courts now offer electronic case-search portals where you can look up filings by party name. If the person has been involved in any litigation, a court filing may provide their last known address. The address on file may be outdated if the case is several years old.
Business and Professional License Filings
If the person owns a business or holds a professional license, public filings can reveal address information. Every state’s Secretary of State office maintains a searchable database of registered business entities. These filings list the names and addresses of corporate officers, directors, LLC members, and registered agents. A registered agent’s address is always public because it serves as the official contact point for legal notices.
Professional licensing boards for fields like medicine, law, real estate, and accounting maintain public directories as well. These typically list the licensee’s name and a business or mailing address, searchable online through the relevant state agency at no cost.
U.S. Postal Service Tools
Ancillary Service Endorsements on Mail
People who send mail regularly can use USPS ancillary service endorsements to track when a recipient moves. Printing “Address Service Requested” on an envelope tells the post office to forward the mail to the recipient’s new address (if they filed a change-of-address order within the past 12 months) and to send the mailer a separate notice with the updated address. An address correction fee applies for the notice. After 12 months, the mail is returned with the new address physically attached to the piece at no charge.2United States Postal Service. 507 Quick Service Guide
Other endorsements work differently. “Return Service Requested” skips forwarding entirely and returns the piece with the new address or the reason it couldn’t be delivered. “Change Service Requested” disposes of the mailpiece but sends the mailer a separate electronic notice of the new address. The right endorsement depends on whether you want the mail to reach the person or just want the address data. These services only work during the window when a change-of-address order is active, which maxes out at 18 months for most mail classes.3United States Postal Service. DMM 507 Mailer Services
Change-of-Address Request for Legal Process
The USPS offers a specific procedure for people who need an address to serve legal documents. Using a standardized request form, you can ask the local postmaster for the new address of someone who has filed a change-of-address order, or for the identity and address of a P.O. box holder. There is no fee for this service.4United States Postal Service. Change of Address or Boxholder Request Format
The request is limited to people who need the information for service of legal process in actual or anticipated litigation. You must provide the names of the parties, the court where the case has been or will be filed, the docket number, and your capacity (attorney, process server, or self-represented party). Submitting false information to obtain an address through this process is a federal crime punishable by a fine of up to $10,000, imprisonment of up to five years, or both, under 18 U.S.C. § 1001.4United States Postal Service. Change of Address or Boxholder Request Format
Outside of this legal-process exception, federal law generally prohibits the Postal Service from disclosing the names or addresses of postal customers to the public.5Office of the Law Revision Counsel. 39 USC 412 – Mail or Other Matter Casual requests for a neighbor’s forwarding address or a former friend’s new location will be denied.
People-Search Sites and Social Media
People-search websites aggregate data from public records, marketing databases, and data brokers into a single report you can purchase. For roughly $10 to $50, these sites compile current and past addresses, phone numbers, and associated names. Data quality varies. Some reports are surprisingly accurate; others recycle outdated information. Treat these results as a starting point, and cross-check any address you find through a second source before relying on it for anything important.
Social media profiles can narrow a search without costing anything. A LinkedIn profile may list a current employer and city. Facebook and Instagram posts sometimes include location tags or photos with identifiable landmarks. None of that gives you a street address directly, but it can confirm what city or region someone lives in, which makes other search methods far more effective. Direct messaging through these platforms is also an option when you’d rather just ask.
If the Person Is in the Military
Each branch of the U.S. military operates a locator service that can forward mail to active-duty, reserve, guard, and retired personnel. The Air Force Worldwide Locator, for example, accepts written requests from the general public. You place a stamped, sealed letter addressed to the service member inside a larger envelope along with identifying details (full name, rank, date of birth, and Social Security number or serial number if known) and a $3.50 fee payable by check or money order. The locator office forwards your letter to the service member’s duty station without revealing the address to you. Active-duty and retired military requesters are exempt from the fee.6Air Force’s Personnel Center. Worldwide Locator
The locator does not release the service member’s address to civilians. It acts as a mail-forwarding intermediary, and the service member can choose whether to respond. Government agencies and law enforcement can request address information directly, but must submit their request on official letterhead. This service only covers people currently receiving military compensation. It does not cover individuals who have separated from the armed forces.6Air Force’s Personnel Center. Worldwide Locator
Hiring a Licensed Investigator
Licensed private investigators and skip-tracing specialists have access to databases the general public cannot reach. These tools pull from utility connection records, cell phone account data, and credit header information (the non-financial portion of credit files that includes names, addresses, and dates of birth). Access to credit header data is regulated by the Fair Credit Reporting Act, which limits who can pull consumer reports and for what purposes.7Federal Trade Commission. Fair Credit Reporting Act Licensed investigators generally qualify under the permissible-purpose requirements for litigation support and debt recovery.8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports
Expect to pay $100 to $500 for a locate, depending on how much identifying information you can provide upfront and how hard the person is to find. A search with a full name, date of birth, and last known city might take an investigator an hour. A search with only a name and a vague geographic area could take days. Investigators verify results against multiple sources before handing over an address, which matters if you’re using it for service of process or a court filing where accuracy has legal consequences.
Discovery and Subpoenas in an Active Case
If you’re already in a lawsuit, the discovery process gives you formal tools to compel address information. During the initial disclosure phase of a federal case, each party must provide the names, addresses, and phone numbers of individuals likely to have relevant information. A party who withholds this can face a motion to compel and court-imposed sanctions.
If the address you need belongs to a non-party, a subpoena directed to a third party who likely has the information is the standard tool. Banks, employers, utility companies, and landlords all maintain billing records with current addresses. A subpoena compels these entities to produce records or appear and testify. Filing fees for subpoena issuance are minimal in most courts. The subpoena must be served on the third party according to the applicable rules of civil procedure.
What You’re Not Allowed to Do
Every method above operates inside a legal framework that restricts how address information can be obtained and used. Violating these laws can result in criminal charges, civil liability, or both.
DMV Records Are Off-Limits
You cannot walk into a DMV and request someone’s address. The Driver’s Privacy Protection Act prohibits state motor vehicle departments from disclosing personal information from their records except for specific authorized purposes.9Office of the Law Revision Counsel. 18 USC 2721 – Prohibition on Release and Use of Certain Personal Information From State Motor Vehicle Records Those exceptions include use by government agencies, use in connection with civil or criminal litigation (including service of process), use by licensed investigators, and use in recovering a debt. Casual curiosity is not on the list. Anyone whose records are improperly disclosed can sue for a minimum of $2,500 in liquidated damages per violation, plus punitive damages and attorney fees.10Office of the Law Revision Counsel. 18 US Code 2724 – Civil Action
No Pretexting a Bank
Federal law makes it illegal to obtain someone’s personal information from a financial institution through false pretenses. Under the Gramm-Leach-Bliley Act, anyone who uses a fake identity, a forged document, or a deceptive statement to trick a bank, credit union, or other financial institution into revealing a customer’s address commits a federal offense.11Office of the Law Revision Counsel. 15 USC 6821 – Privacy Protection for Customer Information of Financial Institutions This applies even if you have a legitimate reason for wanting the address. The method matters as much as the reason.
Credit Files Require a Permissible Purpose
Consumer reporting agencies can only release a consumer report for a permissible purpose defined by federal law. Those purposes include credit decisions, employment screening, insurance underwriting, court orders, and legitimate business transactions initiated by the consumer.8Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports “I want to find out where my ex moved” does not qualify. Any service that pulls actual credit-file data must verify your permissible purpose before releasing it.
Stalking and Harassment
Using any address-finding method with the intent to harass, intimidate, or surveil someone can trigger federal criminal liability. The federal stalking statute covers anyone who uses the mail, the internet, or any other facility of interstate commerce to engage in conduct that places another person in reasonable fear of serious harm or causes substantial emotional distress.12Office of the Law Revision Counsel. 18 USC 2261A – Stalking Every state also has its own stalking and harassment laws. A legitimate search method does not protect you if your purpose is to frighten or control someone.
Address Confidentiality Programs
Roughly 45 states operate address confidentiality programs designed to protect survivors of domestic violence, sexual assault, and stalking. Participants receive a substitute address from the state (typically through the Secretary of State’s office) that replaces their real address on government records including voter registration, driver’s licenses, and court filings. Mail sent to the substitute address is forwarded to the participant’s actual location, which stays confidential.
If the person you’re trying to find is enrolled in one of these programs, the usual public-records methods will return only the substitute address. Courts can order disclosure of the real address in limited circumstances, but the bar is high, and most states require a showing of genuine legal need. Law enforcement can also access the real address in many states. If you encounter a substitute address tied to a state program, that’s a strong signal the person has a safety-related reason for staying hidden.
Which Method Fits Your Situation
Free methods work best when the person isn’t trying to hide. Property records, voter files, and court filings are all public, all free or nearly so, and all searchable from your computer. If the person owns property or has been involved in any legal proceeding, you can often find a current or recent address within an hour.
When free methods come up empty, a people-search site can fill in the gaps quickly for a modest fee. These services are most useful when you have a full name and at least a general idea of location. The less information you start with, the more likely you’ll get results for the wrong person.
If the address is needed for service of process, the USPS boxholder request is free and built for that purpose. For harder searches involving someone who has moved frequently or deliberately dropped off the grid, a licensed investigator with access to proprietary databases is usually the most efficient path. The cost is higher, but investigators verify their results, which saves you from the expensive mistake of serving legal papers at the wrong address.
