Who This Is For

Most people who land here are in one of these situations. Any one of them is reason enough.

• A piece of mail, or a check, was stolen. Yours, a neighbor's, or someone in your zip code.
• A NextDoor post or a local police alert flagged mail theft in your area.
• You travel, and your mailbox sits full for days at a time.
• Tax season. Refund checks, identity-sensitive returns, and financial mail are moving in volume.
• College admissions or the holidays. Acceptance letters, financial-aid offers, gift cards, and monetary gifts are all running through the mailbox.
• Someone in the house finally asked: "What are we actually doing about this?"

The Direct Answer

Mail theft is the unauthorized taking of mail from a mailbox or carrier, and it's treated as a federal offense investigated by the U.S. Postal Inspection Service. You can reduce the risk with a locking mailbox at the curb or door, a secure package box for parcels, and by collecting mail promptly. If your mail is stolen, report it to the U.S. Postal Inspection Service.

What mail theft actually is.

Let's be honest about the problem without catastrophizing it. Mail theft is exactly what it sounds like, someone taking mail that isn't theirs from a mailbox, a cluster unit, or a carrier. The reason it's worth your attention is the math: the highest-value mail you receive, checks, tax documents, replacement cards, is the easiest kind to turn into someone else's money.

In just five U.S. Postal Inspection Service divisions, the USPS Office of Inspector General logged 165,316 mail theft complaints over two fiscal years (2021-2022)¹, roughly 89% of all complaints those divisions received. That's five metro areas. The national picture is larger.

A locked box doesn't solve the whole problem. What it does is take your household off the easiest version of the target list, and that's most of the battle.

Where mail theft happens.

It's less random than it feels. Three patterns cover most of it:

• At the curb. An unlocked post mount mailbox on the street is the most exposed point in the chain, visible, reachable, and empty of any deterrent.
• At the door and on the porch. Wall-mount mail and delivered packages sit in the open while you're at work or away. Porch parcels are their own category of risk.
• In transit and at the cluster. Coordinated, high-volume theft targets collection boxes and delivery routes. You can't control that link, but you control your own mailbox, which is where the everyday risk actually lives.

Knowing your pattern is how you pick the right fix. That's what the rest of this guide is for.

The Adoorn approach: secure mail that still looks like your home.

Most security advice in this category is built to make you afraid. Ours isn't. We're Adoorn, the modern mailbox brand Architectural Digest named "Best Overall," and we think the right answer is the calm one: a mailbox that locks, in heavy-duty galvanized steel, with stainless steel hinges, a rust-resistant powder-coat finish, weatherproof and worry-proof, and that looks like it was chosen instead of bolted on in a panic.

Secure mail shouldn't require turning your front step into a fortress. The point of design-led security is that the protection disappears into the home. Your neighbor sees a great-looking mailbox. You know it locks.

Match Your Home

Match the fix to your home.

Mail theft has one right answer per home, and it depends on where your mail and packages actually land. Find yours.

How do I choose the right mail security for my home?

Three questions, in order.

1. 1Where does your carrier deliver, curb or door?Curb → Locking Post Mount. Door or porch → Locking Wall Mount. (Not sure? It's wherever your mail physically lands today.)
2. 2What triggered this, an event or a season?A theft or area pattern means move now. A high-mail season (tax, admissions, holidays) means move ahead of it.
3. 3Are packages part of the problem?If parcels pile up on the porch, add the Adoorn Package Box to whichever mailbox fits, mail secured at the mailbox, packages secured beside it.

Answer those three and the rest of this page tells you exactly what to do.

What Buyers Tell Us

What to do if your mail has already been stolen.

If it's already happened, here's the calm, correct order of operations:

1. 1Report it to the U.S. Postal Inspection Serviceat uspis.gov/report (or 1-877-876-2455)², the federal agency that investigates mail theft.
2. 2File with your local policea report number helps if identity-sensitive mail was taken.
3. 3Lock down anything exposedif checks, statements, or replacement cards were in the mailbox, contact your bank and consider a credit freeze.
4. 4Close the gap before the next deliveryinstall a locking mailbox so the same mailbox isn't sitting open tomorrow.

Mail theft is alarming, and the response is practical. Most households who get hit do these four things once and never think about it again.

Make secure mail the calm, finished decision.
