What to Consider When Choosing the Best Locking Mailbox?

While locking mailboxes provides an extra level of security for your mail, you should consider a few things before choosing one. Here are some factors to consider when selecting a locking mailbox:

1. Size of the Mailbox

The unit size is one of the most important considerations when choosing a locking mailbox. You’ll want to ensure that the mailbox can accommodate your mail, including larger items such as magazines and catalogs. If you have a lot of outgoing mail, you’ll also want to ensure that the mailbox has enough space for all your letters and packages.

2. Type of Locking Mechanism

Two main locking mechanisms for mailboxes are keyed and combination locks. Keyed locks are the most secure option, as they cannot be picked like combination locks. However, keyed locks can be more difficult to use if you lose your keys. Combination locks are easier to use but are not as secure as keyed locks. Choosing a USPS-approved locking mailbox is important to prevent mail theft and further issues.

3. Material

Another important consideration is the material of the mailbox. Most locking mailboxes are made from metal, which is durable and weather-resistant. However, some models are also available in plastic or wood. If you live in an area with severe weather conditions, you’ll want to choose a mailbox made from a durable material that can withstand the elements.

4. Price

For most people, price is a major consideration when choosing a locking mailbox. You’ll find that prices vary widely, depending on the size, type of locking mechanism, and mailbox material. In general, keyed locks are more expensive than combination locks, and metal mailboxes are more expensive than plastic or wood models.

5. Installation

Some locking mailboxes can be installed by the homeowner, while others must be installed by a professional. If you’re not handy with tools, you’ll want to choose a model that can be easily installed. Most metal mailboxes can be mounted directly to your house or garage, while some plastic and wood models require special brackets for installation.

6. Warranty

You’ll want to choose a mailbox with a warranty to protect your investment. This way, if anything goes wrong with the unit, you can get it replaced or repaired without having to pay for the repairs yourself. Most manufacturers offer at least a one-year warranty on their products.

7. Dimensions

The dimensions of the mailbox are also important to consider. You’ll want to ensure that it’s not too large or too small for your needs. In general, larger mailboxes can accommodate more mail, while smaller units are more space-efficient.

8. Weight

If you plan on installing the mailbox yourself, you’ll need to consider the unit’s weight. Heavier mailboxes can be difficult to install, so you may want to choose a lighter model if you’re not confident in your DIY skills.

9. Design

Locking mailboxes come in various designs, so you’ll be able to find one that fits your home’s style. From traditional to contemporary, there is a locking mailbox to suit every taste. Also, remember that some mailboxes are designed to be mounted on a wall, while others are free-standing.

10. Color

Most locking mailboxes are available in various colors, so you can choose one that coordinates with your home’s exterior. Black and white are the most popular colors for mailboxes, but you’ll also find units in bronze, copper, and other metallic hues. If you want something a little different, brightly-colored mailboxes are available.

The best locking mailbox for your home will depend on your individual needs and preferences. However, by taking the time to consider all of your options, you can be sure to choose a unit that will provide years of security and peace of mind.

Can You Have a Lockable Mailbox?

If you live in a high-crime area or are just concerned about the safety of your mail, you may be wondering if you can have a lockable mailbox. The answer is yes. Several types of locking mailboxes are available on the market, each with its own set of features and benefits.

But remember, USPS members do not open or close your mailbox, so you’ll need to choose a design that meets your needs while accommodating the postal mail carrier.

Are Locking Mailboxes USPS Approved?

Yes, some locking mailboxes are USPS approved for residential use. The US Post Office does not endorse any specific brand, but they have created guidelines that a locking mailbox must meet to be approved.


How Does The Mailman Get Into A Locked Mailbox?

The keyhole on every locking mailbox has a circle that doesn’t belong on the mailbox owner’s key. The mailman’s key has that circle, which works on all boxes. If the keyhole didn’t have that circle, it wouldn’t be postmaster general approved.

Can You Put A Camera On Your Mailbox?

No, you cannot put a camera in your mailbox. The United States Postal Service (USPS) has strict rules about what you can and cannot do to your mailbox. One of those rules is that you cannot put a camera in your mailbox.

Can I Put A Lock On My Mailbox?

Yes, you can put a lock on your mailbox. However, there are some restrictions on what kind of lock you can use. The lock must be approved by the USPS and have a keyhole compatible with the mailman’s key.


With the recent rise in home break-ins and identity theft, safeguarding your mail is more important than ever. A locking mailbox is a great way to protect your mail from thieves, and there are various types to choose from depending on your needs.

If you’re looking for a basic locking mailbox that will deter casual thieves, the Mail Boss 7506 is a great option.
