Another thing that is top-notch about this box is its construction, as it is produced using heavy-duty galvanized steel.

When it comes to color varieties, you have four to choose from. So, you can easily pick the color that is perfect for your individual needs.

Things to Consider

There are different things that you need to look for when buying the best locking mailbox. As your mails, parcels, and mailbox are valuable, it’s necessary to ensure that the product you will buy is sufficiently capable of protecting them all from thieves.

Features to consider while choosing a locking mailbox

6 Best Locking Mailboxes to Keep Your Letters, Newspapers, and Parcels Safe and SoundWhen selecting the ideal mailbox for your needs, there are also some key factors you need to take into consideration. Of course, you don’t want to end up with a unit you can’t use, which makes it important to keep the factors in mind.


There are three primary types of locking mailboxes – the wall mount type, the freestanding type, and the curbside type. A wall mount locking mailbox attaches to your gate, garage, or house, while a curbside model is normally set up on a post close to your curb.

However, the freestanding type, such as the Step2 Deluxe Package Delivery Box, is the only type that stands alone without being supported by anything. Simply put it at your porch, and it’s ready for use. Both the curbside mailboxes and the wall mount mailboxes are commercially used as a drop box.

Materials used

Since security is always the top priority with locking mailboxes, you must ensure that it’s capable of repelling any theft attempt.

Ideally, we recommend you to go for stainless or galvanized steel. Apart from holding up better against break-ins, this material also resists water damage and the elements.

Other material options are aluminum and plastic. If you are not really keen on security, you will be fine with either material as they can be easily broken into. On the upside, materials like aluminum and plastic are always lighter and more straightforward to install. And you can rest assured that it will not degrade or rust quickly. While even coated galvanized steel may start rusting after a couple of years, plastic will remain in peak condition always.

What it’s designed for

When deciding on the model you want to choose, you need to first think about your average mail type. If you, for instance, only receive magazines and envelopes, you won’t need a larger hopper door or large delivery door. That mean you should be fine with either the Gibraltar Mailboxes DVK00000 or the PEELCO Modern Mailbox.

If you, however, receive small to medium-sized packages, you may want to choose the Architectural Mailboxes Oasis 360. For big parcels and larger packages, you should consider one of these models – the PEELCO Package Wall Mailbox, the Mail Boss 7205, or the Step2 Deluxe Package Delivery Box.


The size of the locking mailbox is another key factor you must consider. The width, depth, and height of the box will depend on your requirements. Since these products often come in different sizes, make sure you go for the one that can conveniently accommodate your incoming parcels, envelopes, and mails. If you frequently receive mails, then you need to consider a model with a larger capacity like the Step2 Deluxe Package Delivery Box.

The larger mailboxes are perfect for you if you travel a lot. People who receive only a couple of mails in months should be fine with a small-sized model.


Even though some people may lie to you that a warranty is not really important when buying a mailbox, we advise you to shrug off such talks. It is important to get mailbox with a good warrant so that you can easily get it fixed or replaced if you have an issue with it within the covered period.

Extra features

Some extra features you may need to consider are the number of keys included, if it has a magnetic latch, if it comes with keys, and more


There are many reasons why you need to install a mailbox. Apart from ensuring that you don’t miss your deliveries, a mailbox will also secure your mails and deliveries. Of course, your mails may be stolen if left on your doorstep for too long so that you may benefit from the security provided by a mailbox.

Of course, nearly everything in the world needs to be maintained from time to time, and there is no exception with a mailbox. Apart from making sure it’s clean at all times, you also need to check its support regularly. That is, you must make sure it’s well-anchored.

Mailboxes are vulnerable to rust, especially if it’s left unprotected and exposed fully to the elements, whether it’s snow, sun, or rain. For a simpler answer, a mailbox that’s left unprotected from the elements is likely to rust quickly. If your mailbox is corroding because of oxidation, it’s usually easy to remove the corrosion. To avoid that, however, we advise you to go for a product that’s powder-coated.

With its seamless combination of style, durability, functionality, and uniqueness, you’re certain to spot why we chose this model as our Editor’s Choice.
