If someone is using your address without permission, you can stop it by returning their mail unopened, reporting the misuse to the U.S. Postal Inspection Service and the Federal Trade Commission, locking down your credit, and, when the problem persists, escalating through a cease and desist letter, an injunction, or a civil lawsuit. Learning how to stop someone from using your address is partly about protecting the mailbox and partly about protecting your identity, because the two problems usually travel together.
Handle the Mail the Right Way
Do not open it, and do not throw it out. Taking, hiding, or destroying mail addressed to another person is a federal crime punishable by up to five years in prison, and that penalty applies even when the mail was delivered to your house by mistake or because someone deliberately put your address on it.1Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally
Write “Return to Sender — Person Does Not Live at This Address” on the envelope and put it back in your mailbox with the flag up, or hand it to your carrier. Doing this consistently pushes a signal back through the postal system that the addressee doesn’t reside there, and it creates a trail showing you acted promptly.
If the volume is heavy, go to your local post office and speak with a supervisor. Ask them to flag your address so carriers know only your household should receive deliveries. That doesn’t fix the underlying fraud, but it reduces the daily nuisance while you work the rest of the problem.
Catch the Misuse Early
Most people find out about address misuse only after the damage has started, when a collections letter arrives or an unfamiliar credit inquiry appears. Two free tools shorten that timeline dramatically.
USPS Informed Delivery
Informed Delivery is a free USPS service that emails you grayscale images of the front of every letter-sized piece of mail heading to your address, usually before it arrives. Sign up at USPS.com and verify your identity.2USPS. Informed Delivery – Mail and Package Notifications If mail starts appearing for someone who doesn’t live with you, you’ll know the same day. Informed Delivery also flags a more dangerous variation: someone filing a fraudulent change-of-address form to redirect your mail. If your daily digest suddenly shows nothing for several days, investigate immediately.
Free Credit Reports
Someone using your address may also be using your name. You can pull free weekly credit reports from Equifax, Experian, and TransUnion through AnnualCreditReport.com, a program the bureaus have made permanent, and Equifax offers six additional free reports per year through 2026.3Federal Trade Commission. Free Credit Reports Look for accounts you didn’t open, addresses in the “address history” section you don’t recognize, and hard inquiries from companies you’ve never contacted.
Report the Fraud to the Right Agencies
Returning envelopes stops nothing on its own. Reporting triggers investigations, and three federal entities handle different pieces.
U.S. Postal Inspection Service
The Postal Inspection Service investigates crimes involving the mail system, including fraudulent use of an address. File online through their reporting portal or call 1-877-876-2455.4United States Postal Inspection Service. Report – United States Postal Inspection Service Include copies of misdirected mail (never originals), the dates you first noticed the pattern, and any identifying details about the person named on the mail. If you suspect a fraudulent change-of-address form, report it specifically; Postal Inspectors treat that as a serious offense.5United States Postal Inspection Service. Change of Address Scams
FTC and IdentityTheft.gov
The FTC collects fraud reports into Consumer Sentinel, a database used by law enforcement nationwide.6Federal Trade Commission. ReportFraud.ftc.gov If the address misuse is tied to identity theft, file at IdentityTheft.gov instead. The site generates a personal recovery plan, pre-filled dispute letters, and an official FTC Identity Theft Report that you can hand to creditors, banks, and police to prove you’re a victim.7Federal Trade Commission. IdentityTheft.gov
Local Police
A police report creates an official record that strengthens every later step. Creditors often require a report number before they’ll remove fraudulent accounts. Bring your evidence, your log of incidents, and any FTC report you’ve already filed. Even if the police don’t launch a full investigation, the report itself is a document with weight.
When Debt Collectors Come After You
One of the most stressful side effects of address misuse is getting calls and letters from collectors chasing the other person. You have specific rights when this happens.
After the collector’s first contact, they must send you a validation notice within five days. You then have 30 days to send a written dispute letter stating that the person named does not live at your address and that you do not owe the debt, and asking for verification. Send it by certified mail with return receipt. Once the collector receives your dispute, they must stop all collection activity until they send written verification.8Federal Trade Commission. Debt Collection FAQs
If the collector keeps contacting you after your dispute, or uses abusive tactics, report them to your state attorney general, the FTC, and the Consumer Financial Protection Bureau. You can also sue within one year of the violation. Even without proof of financial harm, a court can award up to $1,000 per violation plus attorney’s fees.8Federal Trade Commission. Debt Collection FAQs
Document Everything
Every action you take should generate a paper trail. Keep a running log with the date each piece of misdirected mail arrived, the name on the envelope, the sender, and what you did with it. Photograph each piece before writing “Return to Sender” on it. Save screenshots of any Informed Delivery digest that shows mail for someone who doesn’t live with you. If collectors call, record the date, time, company name, and what was said. Keep copies of every complaint you file, along with confirmation numbers from the Postal Inspection Service, your FTC report, and any police report numbers. Organized evidence is what turns a vague complaint into a case a prosecutor or judge can act on.
Legal Options When Reporting Isn’t Enough
If the misuse continues after you’ve reported it and returned the mail, formal legal tools give you enforceable remedies. Which one fits depends on how serious the situation is and whether you know who’s responsible.
Cease and Desist Letter
A cease and desist letter is a formal written demand, usually drafted by an attorney, telling the person to stop using your address. It doesn’t carry the force of law on its own, but it puts the recipient on notice that you’re aware of the misuse and prepared to act. It typically sets a compliance deadline and warns of the next step. Many recipients stop at this stage because a letter from an attorney signals that the cost of continuing has just gone up.
Injunction
An injunction is a court order that legally prohibits someone from using your address. You file a petition and present evidence that the misuse is causing you harm or is likely to. If the court grants it, violating the order means contempt charges, which can result in fines or jail. This is the strongest tool short of a full lawsuit.
Civil Lawsuit
If the misuse has caused real financial losses, such as damaged credit, lost work time, or costs to fix the problem, a lawsuit lets you recover those damages. You can also ask the court for a permanent injunction as part of the judgment. When the conduct was especially deliberate or harmful, courts may award punitive damages on top of your actual losses.
Criminal Exposure for the Person Using Your Address
Address misuse tied to a scam isn’t just a civil matter. Anyone who uses the postal system as part of a fraudulent scheme faces up to 20 years in federal prison. If the fraud involves a presidentially declared disaster or affects a financial institution, the maximum climbs to 30 years and a fine of up to $1,000,000.9Office of the Law Revision Counsel. 18 USC 1341 – Frauds and Swindles
When someone uses your personal information, including your address as part of a broader scheme, to commit a felony like fraud or theft, federal law adds a mandatory two-year prison sentence on top of the sentence for the underlying crime, and that time runs consecutively. For identity theft connected to terrorism, the mandatory add-on is five years.10Office of the Law Revision Counsel. 18 USC 1028A – Aggravated Identity Theft
State laws vary. In many states, identity-related fraud becomes a felony once the financial harm crosses a threshold, often between $1,000 and $5,000. Mandatory restitution and additional prison time are common when the fraud is large-scale or targets vulnerable people. Checking your own state’s statutes, or asking a local attorney, is worth the time if you’re weighing whether to press charges.
If a Business or Tax Filing Uses Your Address
Address misuse sometimes goes beyond personal mail. Someone may register a business or LLC at your home address without your knowledge, or use your address on fraudulent tax filings.
For a business registration, contact your state’s Secretary of State or business filing office. In most states, the office won’t simply erase a registration, but you can usually submit a notarized statement of fact disputing it, which becomes part of the public record. If the business entity refuses to update its records, you may need to resolve the issue in court.
For tax fraud, such as someone using your address to file business tax returns or W-2 forms, file IRS Form 14039-B, the Business Identity Theft Affidavit. It’s designed for businesses, trusts, estates, and tax-exempt organizations whose information has been misused for fraudulent tax filings. Submit it if you receive IRS notices about returns you didn’t file, balance-due notices for debts you don’t owe, or rejection notices for e-filed returns because the IRS already has one on file for the same period.11Internal Revenue Service. Report Identity Theft for a Business
Protect Your Address Going Forward
Once you’ve cleared the immediate problem, a few measures make it harder for anyone to misuse your address again. A credit freeze prevents lenders from accessing your credit report entirely, which stops anyone from opening new accounts in your name. You can freeze and unfreeze your reports for free at all three major bureaus.12Consumer Financial Protection Bureau. What Is a Credit Freeze or Security Freeze on My Credit Report
A fraud alert is less restrictive: it stays on your report and requires creditors to verify your identity before issuing new credit. An initial fraud alert lasts one year. If you’ve filed an FTC identity theft report or a police report, you can place an extended fraud alert that lasts seven years and removes you from marketing lists for pre-approved credit offers.13Federal Trade Commission. Credit Freezes and Fraud Alerts
Keep Informed Delivery active. It takes two minutes each morning and is the fastest way to spot new unauthorized mail before it becomes a bigger problem. When you’re away, use USPS Hold Mail to pause deliveries for up to 30 days so mail doesn’t sit in an unwatched box.14USPS.

Catching a problem in week two is far easier to fix than finding it six months in.3Federal Trade Commission. Free Credit Reports
