From rising package theft and identity concerns to HOA-friendly curb appeal, locking mailboxes are more popular than ever. But if you're new to the world of secure mail delivery, you've probably got a few questions (totally normal). This guide answers common locking mailbox FAQs, helping you find the right fit for your home, lifestyle, and peace of mind.
Whether you’re upgrading your current mailbox, replacing an outdated setup, or outfitting a new post box build, here's what to know about locking mailboxes and why The Malone Locking Mailbox is the trusted choice for modern homeowners wanting style and security.
What Is a Locking Mailbox, and How Does It Work?
A locking mailbox is a secure mailbox designed to keep your mail ultra-safe until you’re ready to collect it. Most of them feature a locked compartment with a key-access door, as well as a mail slot or opening that allows the USPS to drop items inside without needing a key.
💡 Good to Know: According to the U.S. Postal Inspection Service, mail theft is a growing concern, especially in suburban and urban areas. A locking mailbox is a proactive way to protect your identity, packages, and other sensitive information.
At Post & Porch, The Malone Locking Mailbox uses a dual-layer security system.
The Malone features a stainless steel mail slot for letters and a separate, locked access panel, allowing you to retrieve the contents with ease. The locking compartment is discreetly integrated into the mailbox’s clean, modern design, maintaining both function and curb appeal.

Are Locking Mailboxes Approved by USPS?
Yes, locking mailboxes are approved by the USPS, but they must meet certain guidelines. The USPS allows locking mailboxes, provided the incoming mail slot is large enough to accommodate standard mail and does not require the postal carrier to unlock the mailbox.
These are the USPS guidelines for locking mailboxes:
- The mail slot must be large enough to accept standard mail, including letters and parcels
- Postal carriers must not need a key or code to deliver mail
- Unrestricted delivery access is required
- Design must be secure, weather-resistant, and functional
The Malone Locking Mailbox is USPS-compliant, featuring a wide, tamper-resistant mail slot that meets postal delivery standards, without compromising on security or style. Shop here →
Can a Locking Mailbox Receive Packages?
Locking mailboxes can typically receive small padded envelopes and letters, but not large parcels or big boxes. If you frequently receive huge packages, consider pairing your locking mailbox with a secure parcel post box or coordinating deliveries right to your door.
💡 Pro Tip: If you want USPS to leave larger packages at your door instead of trying to fit them in your mailbox, you can submit your preference through USPS Informed Delivery, a free service that gives you more control over how your mail and packages are handled.
The Malone Locking Mailbox is ideal for homeowners who want to protect sensitive mail, checks, bills, and small packages, without worrying about prying hands or the elements. See how The Malone Mailbox stacks up against Mother Nature in our new Post & Porch blog here →
What Happens If You Lose the Key to Your Locking Mailbox?
Losing the key to your locking mailbox isn’t the end of the world, friends, but it’s important to know your options (because they are out there!). Here’s what you can do if it happens:
- Contact the manufacturer to request a replacement locking mailbox key
- Call a locksmith to rekey or replace the mailbox lock, especially if it’s a proprietary system
- Replace the entire lock if it’s a standard or universal model – often an easy DIY fix
💡 Pro Tip: Always keep one key in a secure backup location – like a fireproof safe, lockbox, or trusted key cabinet – to avoid lockouts or unnecessary hassle down the road.
The Malone Locking Mailbox comes with two sturdy keys and features a high-quality lock that’s both durable and replaceable. Unlike cheaper locking mailboxes that rely on thin metal or low-grade parts, The Malone Mailbox is engineered for long-term performance, so you don’t have to worry about rusted locks, jammed compartments, or frustrating access over time.
Are Locking Mailboxes Worth It?
Yes – locking mailboxes are worth it because they offer peace of mind and long-term security. Whether you're protecting against identity theft, porch theft, or just want a cleaner way to handle your mail, a locking mailbox is one of the smartest home upgrades you can make.
Plus, if you choose a well-designed modern model like The Malone, you're getting:

Can Locking Mailboxes Rust or Leak?
Locking mailboxes won’t rust or leak if you choose the right materials.
Many budget-friendly locking mailboxes are made with thin sheet metal or flimsy construction that can rust, warp, or leak after just one season. Poor welding, exposed seams, and low-quality finishes make these mailboxes vulnerable to moisture, particularly in areas with heavy rainfall, snow, or high humidity. Over time, that corrosion doesn’t just damage the look of your mailbox – it can weaken the lock and compromise the security of your mail (this does affect curb appeal!).
💡 Pro Tip: Avoid locking mailboxes with exposed locks, thin metal doors, or poorly welded seams. These weak spots are more likely to corrode, leak, or fail entirely – especially during storm season in Arkansas or in coastal climates like Florida.
The Malone Locking Mailbox is built from heavy-duty, 14-gauge American steel and finished with a rust-resistant powder coat for year-round protection. Its seamless, weather-tight construction prevents water intrusion, while its clean, modern mailbox design resists wear from sun, wind, and fluctuating temperatures. Crafted in the U.S. and rigorously tested for all four seasons, The Malone delivers both style and substance you can count on.

Do Locking Mailboxes Deter Theft?
Yes – locking mailboxes are one of the most effective ways to reduce mail theft. While no modern mailbox is completely theft-proof, a high-quality locking system serves as a powerful deterrent by making mail more difficult to access and less appealing to opportunistic thieves.
According to the USPS, mail theft is on the rise nationwide, with thousands of reported incidents annually, and many more going unreported. Thieves often look for easy targets, such as unlocked mailboxes, overflowing mail, or homes with no visible security measures.
💡 But locking mailboxes change that. In fact, a 2023 study by the National Crime Prevention Council found that visible home security features – including locked mailboxes, cameras, and motion lights – deterred over 70% of opportunistic mail theft attempts.
By choosing a secure, weather-resistant locking mailbox like The Malone, you instantly make your home a harder target. Its heavy-duty steel construction, discreet mail slot, and dual-lock system make casual theft far more difficult, discouraging would-be thieves from attempting it.
