Intercepting someone else’s mail is illegal under federal law. Several statutes in Chapter 83 of Title 18 of the U.S. Code criminalize taking, opening, hiding, destroying, or fraudulently redirecting mail that isn’t yours, and most of them are felonies with maximum sentences of five years in federal prison and fines up to $250,000. The rules apply to letters, bank statements, and packages alike, and they protect mail from the moment it enters the postal system until it reaches the person it’s addressed to.
What the Law Treats as Interception
The conduct covered is broader than reaching into a stranger’s mailbox. Under 18 U.S.C. § 1702, taking any mail from a post office, mailbox, or carrier before it reaches the addressee is a felony when the person acts with intent to obstruct the correspondence or pry into someone else’s affairs.1Office of the Law Revision Counsel. 18 USC 1702 – Obstruction of Correspondence Section 1708 separately criminalizes stealing mail, obtaining it through fraud or deception, and knowingly possessing stolen mail.2Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally
Several everyday acts fall squarely inside these statutes:
- Opening mail addressed to someone else to read what’s inside or keep it from reaching them.
- Throwing away or destroying another person’s mail. A landlord who tosses a former tenant’s mail instead of returning it to the carrier is flirting with federal charges.
- Filing a fraudulent change-of-address form to redirect someone else’s mail. Section 1708 covers obtaining mail “by fraud or deception,” which is what a fake forwarding request does. This tactic shows up in identity theft schemes and domestic disputes.2Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally
- Receiving or holding onto mail you know was stolen. You don’t have to be the one who took it; possession of stolen mail carries the same five-year maximum.2Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally
- Damaging or tearing down a mailbox, or destroying mail inside one, which Section 1705 addresses separately.3Office of the Law Revision Counsel. 18 USC 1705 – Destruction of Letter Boxes or Mail
Prosecutors pick a statute based on what the person actually did. Grabbing a package off a neighbor’s porch tends to fall under Section 1708. Opening a roommate’s letter to read it tends to fall under Section 1702.
When Intent Decides the Case
Intent is what separates a federal crime from an honest mistake. Section 1702 requires that the person acted “with design to obstruct the correspondence, or to pry into the business or secrets of another.”1Office of the Law Revision Counsel. 18 USC 1702 – Obstruction of Correspondence Without that purpose, the statute doesn’t reach the conduct.
If your neighbor’s credit card statement lands in your box and you open it without looking at the name, there’s no crime. If you see the name, open it anyway because you’re curious about their finances, and then throw it out, you’ve met both prongs: prying into someone’s business and obstructing their mail.
Section 1708 operates a little differently. The intent is built into the act itself. You can’t accidentally steal a package from a porch or accidentally submit a fraudulent change-of-address form.
Penalties for Mail Crimes
Most mail offenses are felonies, and the exposure is real:
- Obstruction of correspondence under Section 1702: up to five years in federal prison, a fine up to $250,000, or both.1Office of the Law Revision Counsel. 18 USC 1702 – Obstruction of Correspondence4Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
- Mail theft under Section 1708: up to five years, a fine up to $250,000, or both.2Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally4Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
- Mailbox destruction under Section 1705: up to three years, a fine, or both.3Office of the Law Revision Counsel. 18 USC 1705 – Destruction of Letter Boxes or Mail
- General obstruction of mails under Section 1701: up to six months, a fine, or both. This one is a misdemeanor.5Office of the Law Revision Counsel. 18 USC 1701 – Obstruction of Mails Generally
The $250,000 ceiling comes from 18 U.S.C. § 3571, the general federal felony fine statute.4Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine Actual sentences depend on the facts, the defendant’s ability to pay, and federal sentencing guidelines.
When interception is tied to a larger scheme like identity theft, credit card fraud, or wire fraud, prosecutors can stack charges that push total exposure well past five years. A case that starts with a stolen credit card offer pulled from a mailbox can grow into decades of combined sentencing exposure.
Package Theft From a Porch
Taking a package off someone’s doorstep is covered by Section 1708. The statute reaches items “left for collection upon or adjacent to a collection box or other authorized depository,” which includes packages delivered to a porch, apartment lobby, or similar spot.2Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally A conviction is a felony carrying up to five years.
Not every porch theft is handled federally. A single opportunistic grab is often investigated by local police and charged under state theft laws. Serial thieves, organized rings, and cases involving items shipped through USPS are more likely to draw the U.S. Postal Inspection Service and federal prosecutors.
What Is Not a Crime
The statutes require deliberate wrongful intent, and several common situations sit outside their reach.
Opening a misdelivered letter by accident is not a crime. The right response is to mark it “Return to Sender” or “Wrong Address” and put it back in a mailbox for the carrier. Throwing it away is the wrong move, because discarding mail you know isn’t yours starts to look like obstruction.
Parents can open mail addressed to their minor children. USPS delivery standards allow mail for minors to be delivered to their parents or guardians.6United States Postal Service. Domestic Mail Manual – Recipient Services That authority ends when the child turns 18. Opening an adult child’s mail without permission is treated like opening a stranger’s.
Executors and administrators of a deceased person’s estate can handle the decedent’s mail. If you shared an address with the person who died, USPS allows you to open and manage their incoming mail. Forwarding it to a different address requires a visit to a post office with proof that you’re the authorized executor.7United States Postal Service. How to Stop or Forward Mail for the Deceased
Employees authorized to open company mail are fine. An office manager handling the business’s daily mail is doing a job. Opening a coworker’s personally addressed mail that happens to arrive at the office is a different situation.
If You Think Your Mail Is Being Taken
The hardest part of mail theft is often knowing it’s happening. USPS offers a free service called Informed Delivery that sends daily email previews of letter-sized mail heading to your address, along with package tracking.8United States Postal Service. Informed Delivery – Mail and Package Notifications If a scanned piece of mail never arrives, you have evidence something went wrong. Enrolling before you have a problem also keeps a thief from registering your address first.
Report suspected theft or interception to the U.S. Postal Inspection Service, the law enforcement arm of USPS. You can file online at mailtheft.uspis.gov or call 1-877-876-2455.9United States Postal Inspection Service. Report For a theft in progress, call 911 first; USPIS directs people to local police for crimes happening in real time.
Include specifics when you report: what’s missing, when you expected it, any surveillance footage, and any patterns you’ve noticed. Reports feed into how USPIS identifies hotspots and builds cases against repeat offenders, even when a single incident doesn’t lead to an arrest. A locking mailbox, typically $130 to $250 installed, cuts your exposure in neighborhoods with curbside delivery.
