How to Look Up Someone’s Address: Public Records and Legal Limits

To look up someone’s address, start with the free public records that governments already publish: county property and tax rolls, court dockets, and secretary of state business filings. Those three sources cover most homeowners, litigants, and business operators without any fee. If you have a legal reason, the U.S. Postal Service and military locator services offer additional paths. Paid people-search sites are fast but often wrong, and a few sources — DMV records in particular — are off-limits under federal law.

County Property and Tax Records

If the person owns real estate, the county is usually the fastest answer. Every county links property owners to their parcels for tax assessment, and most now publish that data through free online portals run by the assessor or tax collector. Type in a first and last name, and the system returns any parcels that person owns in the county.

The result typically shows the “situs address,” which is the physical location of the property. For a homeowner, that is effectively the residential address. You’ll also see a mailing address on file for tax correspondence, which sometimes differs if the owner uses a P.O. box.

Two catches. You have to guess the right county, which is impractical across thousands of jurisdictions if you have no lead. And renters won’t appear because only the owner’s name is on the record. When you already have a rough idea of where someone lives, though, the county assessor’s site is the best first move.

Court Records and Case Filings

Lawsuits, divorces, evictions, criminal cases, and probate proceedings routinely list the residential addresses of the people involved. Under the Federal Rules of Civil Procedure, a summons must state the plaintiff’s attorney’s address or, if unrepresented, the plaintiff’s own address. Federal filings follow similar patterns for other parties.

Courts redact Social Security numbers and financial account numbers, but residential addresses generally stay visible in the public index. If the person has any court history where you’re looking, the address is often sitting in the docket.

Federal Cases Through PACER

The Public Access to Court Electronic Records system covers bankruptcy filings, federal lawsuits, and criminal cases across all federal district and appellate courts. PACER charges $0.10 per page with a $3.00 cap per document, and if your total charges stay at $30 or less during a billing quarter, the fees are waived entirely. Bankruptcy filings are especially useful because debtors must list their current residential address on the petition.

State and Local Dockets

State courts handle most civil and criminal cases, and their records are commonly searchable through the clerk of court’s website. Family law cases almost always list home addresses. Eviction filings name both landlord and tenant with addresses. Small claims filings do the same.

Secretary of State Business Filings

Anyone who owns or operates a business has probably filed paperwork that includes an address. Every state requires LLCs and corporations to designate a registered agent and provide an office address when they form or register to do business. These filings are public and searchable through the secretary of state’s website in each state, usually at no cost.

Search the business entity database for the person’s name, and you’ll see any companies where they appear as an officer, director, member, or registered agent. Filings typically show the registered agent’s physical address, the principal office address, and sometimes the mailing address of individual officers. Sole proprietors who registered a trade name or DBA appear too. It’s a strong tool for business owners and useless for anyone with no formal business tie.

Address Requests to the U.S. Postal Service

The Postal Service will disclose a current address or forwarding address, but only if you need it to serve legal process. This isn’t a casual lookup tool. The governing regulation, 39 CFR § 265.6(d)(5)(ii), limits access to process servers, attorneys, and parties representing themselves in litigation.

You send a written request to the Postmaster at the post office serving the person’s last known ZIP code. The request must state your legal capacity (process server, attorney, or self-represented party), cite the statute or regulation authorizing service (attorneys and self-represented individuals are exempt from this piece), give the case name, court, and docket number if one exists, and identify the role in which the person is to be served, such as defendant or witness. Signing the request certifies under penalty that the information will be used solely for service of legal process.

The USPS provides a standard format for these requests at the end of the regulation text, and it requires that the format be used in its entirety if you submit on your own letterhead. Missing information or a missing signature gets the request returned. One important limit: if the person has filed a protective court order with their local post office, the USPS will not disclose the address through this process.

Active-Duty Military Personnel

There is no public database for service members. Each branch operates a worldwide locator that forwards correspondence, and in some cases provides a duty station address, in response to a written request.

The Air Force Worldwide Locator, for example, wants the service member’s full name with middle initial, rank, and Social Security number or serial number and date of birth, along with a $3.50 fee and a stamped, addressed envelope bearing the service member’s name. The locator forwards your letter rather than handing over the address. Active-duty members, reservists, and military retirees are exempt from the fee.

The Army, Navy, and Marines run similar services through their personnel centers. The Coast Guard does not offer a locator. For emergencies, the American Red Cross can help relay urgent messages. These services only cover people currently receiving military compensation, so separated or discharged members without benefits won’t appear.

Voter Registration Records

Most states treat voter rolls as public records that include the voter’s name and residential address, but access rules vary widely. Some states allow anyone to view voter data through an online portal. Others restrict access to political parties, candidates, researchers, or requesters with a specific legal purpose. A handful of states let voters opt out of public disclosure. Bulk voter data fees typically run from around $30 to $100, and individual lookups through online portals may be free where they exist. Worth a check when other avenues come up empty.

Commercial People-Search Sites

Paid platforms like Spokeo, BeenVerified, and TruthFinder aggregate public records, marketing databases, and utility connections into profiles that include current and past addresses. A single report typically costs between $1 and $50, with monthly subscriptions for heavier users. Type in a name, get a consolidated report in minutes.

Accuracy is genuinely uneven. The underlying databases aren’t always updated, and reports can carry outdated addresses, mismatches between people with similar names, or phantom listings that fuse two different people into one profile. Treat any result as a lead that needs verification against a primary public record before you act on it.

Free Digital Search Tips

A few free moves can save you time before you pay for anything or file a formal request. Searching a full name in quotation marks together with a city or state name often surfaces public records hits, tagged social media posts, or professional directory listings. Business networking profiles routinely display a metro area, which at least narrows the geography.

Many professionals have a business address listed through state licensing boards. Doctors, lawyers, real estate agents, contractors, and dozens of other licensed occupations show up in state regulatory databases that are free to search. Listings usually show the business address and sometimes a home address, depending on state and profession.

If you know the employer, a secretary of state filing confirms the business location even if it doesn’t give you a home address. White pages directories still list residential entries for people who haven’t opted out. And if the person has appeared in local news, newspaper archives sometimes include neighborhood-level detail.

What You Cannot Legally Do

Some address sources are off-limits, and misusing address information can be a crime on its own.

DMV Records Are Not Available

The Driver’s Privacy Protection Act (18 U.S.C. §§ 2721–2725) broadly prohibits state motor vehicle departments from disclosing personal information, including a person’s name, address, and telephone number. You cannot hand over a license plate number and receive a home address.

The DPPA carves out narrow exceptions. Government agencies can access the data for official functions. It’s available for civil, criminal, or administrative proceedings, including service of process and investigation in anticipation of litigation. Licensed private investigators and insurance companies have access for statutorily permitted purposes. Businesses can access records to verify information or recover debts. Personal curiosity is not on the list. Violations carry criminal fines, and the person whose information was improperly disclosed can sue for actual damages, punitive damages, and attorney’s fees.

Stalking and Harassment Laws

Using an address to monitor, follow, or intimidate someone can trigger federal criminal charges. Under 18 U.S.C. § 2261A, it’s a federal crime to use the mail or any electronic communication service to engage in a course of conduct that places someone in reasonable fear of death or serious injury, or that causes substantial emotional distress. The statute specifically covers surveillance conducted with intent to harass or intimidate. Most states have their own stalking and harassment laws with similar or broader scope. Looking up an address for a legitimate reason is legal; using it to cause fear or harm is not.
