How to Choose a Locking Mailbox

First, there are several key considerations to make when choosing a locking mailbox for your home or business. Those are:

  • Mailbox Type – Generally, there are wall-mounted and curbside mailboxes. In most cases, curbside mailboxes accept larger mail, such as small packages, while wall-mounted boxes are limited to envelopes.
  • Materials – Most locking mailboxes are made of galvanized steel. Check the gauge number because lower gauge numbers equal thicker steel.
  • Size – Most companies will list the dimensions of the box as well as the size of the mail it accepts. To land on the right size, match the size of the mail you typically receive to the maximum parcel acceptance size of the box.
  • Security – Most boxes feature rear or front locking doors. Also, you’ll find that some boxes feature both rear and front. Additionally, it’s wise to check the style of lock because the most secure locking mailboxes should offer pick resistance.
  • Hardware – Most boxes do not include mounting hardware. For this reason, you’ll find that most companies will try to sell you a compatible post. It’s up to you whether you want to buy a post from them or use your own.
  • USPS Approval – The top companies in this space all offer USPS-approved boxes to guarantee that you’re in compliance.
  • Warranty – All of the reliable locking mailbox manufacturers offer warranties. Typically, the warranties range from 90-day to Limited Lifetime.

Beyond those considerations, you’ll find that choosing a box comes down to your taste. There are a variety of colors and finishes to choose from to match your home’s design.

Best Locking Mailbox Reviews

Below, we share our individual reviews of each mailbox from the table above.

#1) Mail Boss Mail Manager Street Safe Latitude

If one thing is for sure, Mail Boss is one of the leaders in the locking mailbox space. You’ll find that all Mail Boss boxes are built with heavier duty steel and better security features than competing boxes. Because of this, Mail Boss models found three spots in our top five picks. First, let’s go over what the Mail Manager Street Safe – Latitude model brings to the table.

Currently, this box is available in both rear-locking and front & rear-locking models. Depending on the configuration of your box, you may find that the dual-door design is more convenient since you may be able to retrieve your mail from your car. Next, the capacity of the box and baffle door makes the Latitude a good choice for all envelopes, padded envelopes, and small packages.

Regarding security, this box delivers on all fronts. In total, it protects against picking with its 12-disc wafer lock, stainless steel hinges, anti-pry latch, and heavy-duty steel construction. Plus, there’s a clip to attach your outgoing mail, so you won’t need to sacrifice that convenience. Overall, this is a good all-around locking mailbox that provides complete security for a fair value.

Pros

  • Front & rear locking version available
  • 12-disc wafer lock for pick resistance
  • Heavy-duty steel protects against brute-force attacks
  • The patented anti-pry latch lock prevents successful crowbar and screwdriver attacks
  • Enough capacity to accept small packages
  • Limited Lifetime Warranty

Cons

  • The outgoing mail clip could be better
  • You may desire a box with a larger opening for packages
  • Heavy rain may lead to moist mail

#2) Mail Boss Package Master

Now, if you want to be able to receive larger packages than the Latitude model accepts, yet you don’t want to invest in a secure package delivery box, the Package Master is the perfect solution. It’s large enough to accept most small and medium packages, yet it still functions as a curbside mailbox. For people who often make online orders for supplements, beauty products, and other similar items, the Package Master is a good choice.

Similar to the Latitude model, you know you’re getting heavy-duty steel construction with this box. Actually, 12 and 14-gauge steel is the same thickness you’ll find on some home jewelry safes to give you an idea of how tough this box is. And at 53 lbs, you know it’s substantial. With that being said, you’ll definitely want to make sure you have a post that can support the Package Master.

To give you an idea of the package size this box accepts, the max parcel dimensions are 10.5” L x 4.5” W x 4.5” H. Also, instead of a clip for outgoing mail, the Package Master features a slot at the top of the mailbox as well as a mail flag. Finally, one cool feature is the addition of neodymium magnets to keep the door closed and your mail dry.

Pros

  • Accepts larger packages than the Latitude model
  • Outgoing mail slot instead of a clip
  • Includes the Mail Boss FAST-TRAK mounting clip for easy installation on any post
  • Enough capacity for small business owners or large families
  • Includes reflective house numbers and a floor liner
  • Limited Lifetime Warranty

Cons

  • Some mailmen may get confused about how to use it (it’s recommended to use labeling)
  • Your mail person may use the outgoing mail tray to deliver mail
  • Heavy for a single person to lift during installation

#3) Architectural Mailboxes The Oasis 360

Another leader in the locking mailbox space is Architectural Mailboxes. Comparatively, Architectural Mailboxes offers very similar designs to Mail Boss. Though, you’ll notice that Architectural Mailboxes doesn’t use the same gauge steel. This particular model, The Oasis 360, sports 17 to 24-gauge steel, which isn’t as heavy as the steel on the two preceding boxes. Having said that, steel is steel, and since this is a mailbox and not a safe, the steel on The Oasis 360 is still sufficient.

So, if you prefer a lighter weight secure mailbox, The Oasis 360 is a good choice since it is more than 10 lbs lighter than the Mail Boss Latitude. Presently, this box is available in several finishes, including Pewter, Black, White, and Rubbed Bronze. Next, each box offers convenient rear and front keyed access to your mail. As for package size, the maximum size The Oasis 360 accepts is 9.5″ W x 12.6″ L x 1.5″ H to 9.5″ W x 3.5″ L x 2.5″ H.

Similar to most locking mailboxes, this model does not include the required mounting hardware, yet it does offer four pre-drilled mounting holes to mount it to your post of choice. Finally, Architectural Mailboxes matches Mail Boss with a Limited Lifetime warranty, and there is a clip in The Oasis 360 for outgoing mail.

Pros

  • A worthy alternative to Mail Boss models
  • Available in multiple finishes to match your home
  • Front and rear locking doors
  • Large enough to accept small packages and padded envelopes
  • Unlikely to confuse mailmen
  • Limited Lifetime Warranty

Cons

  • Not as heavy-duty as a Mail Boss box
  • The locks aren’t as secure as Mail Boss
  • Requires the addition of a mounting plate or post

#4) Mail Boss Metro

Now for the best wall-mounted locking mailbox. Mail Boss delivered again with its sleek Metro model that gets the job done for both suburban and urban applications. The simple yet effective design ensures that no one will steal your sensitive mail, which could lead to identity theft. However, unlike the preceding boxes, it’s important to note that this box is unlikely to accept packages larger than a padded envelope.

Next, you get the same rugged Mail Boss construction with this box at 14 and 16-gauge steel. At 18 lbs, this is a heavy-duty wall-mounted mailbox, so make sure to mount it appropriately. The box itself features a front-facing locking door at the bottom that’s large enough to allow for easy access to your mail. Plus, it features the same anti-pry design as the Mail Boss models above.

Another advantage of choosing this box is that it includes the Mail Boss FAST-TRAK mounting bracket. Compared to Architectural Mailboxes, you get a mounting bracket rather than just pre-drilled holes. Lastly, the box comes with three laser-cut brass keys to supply your family.

Pros

  • A sleek yet substantial mailbox at 18 lbs
  • A large locking door for easy access to your mail
  • Anti-prying design
  • The same secure lock as other Mail Boss models
  • Includes three keys
  • Plenty of finishes and colors to choose from

Cons

  • Not built to accept packages
  • The included screws could be of better quality
  • The steel isn’t as thick as the curbside Mail Boss models above

#5) Gibraltar Designer

Last up is the most affordable locking mailbox in our guide that also happens to offer the most basic security. Compared to the preceding boxes, this box is lighter and built for minimal security. With that being said, it does get the job done in areas with minimal risk where homeowners desire a wall-mounted secure mailbox.

To give you an idea of the difference between this box and the Metro model above, this one weighs 3.5 lbs while the Metro weighs 18 lbs. In other words, this box may feel flimsy if you previously handled a Mail Boss box. Next, this locking box features a slot to accept letters rather than a swinging door. As a result, this box is made to accept letters only.

Additionally, the box must be installed in a covered area to avoid getting your mail wet in rainy conditions. A couple of final features worth highlighting are the concealed cam lock beneath the swinging lid, and Gibraltar mailboxes are made in the USA.

Pros

  • Backed by a 90-day limited warranty
  • Made in the USA
  • The swinging lid conceals the mail slot
  • Available in several finishes to match your home

Cons

  • Not built for high-volume mail
  • Will not accept large envelopes or packages
  • The stick-on “Mail” emblem is made of plastic

Bottom Line

Choosing the best locking mailbox for your home or business comes down to your needs and preferences. Like all things in life, each box comes with its own pros & cons. The trick is to land on the box that will accommodate your mail and family.

If one thing is for sure, Mail Boss is the leader in the secure locking mailbox space at the moment. Mail Boss boxes are built with the heaviest steel, most secure locks, and come backed by the longest warranty. However, each box is not perfect since you may run into problems with your mail delivery.

In the event that your mail person is confused about how to use the box, a short, friendly conversation could go a long way to have your mail delivered correctly. If all else fails, there’s always the option to whip up some labeling on your computer and attach it to the inside of the box to instruct your mail person.
