Contemporary or traditional mailboxes installed on your curbside, are pretty smaller and do not have a lock. Having a mailbox without a lock would mean easy ways for thefts to take place.

Mail thefts are common and require some ways to curb it. Applying a lock to it is not possible, hence upgrading the mailbox to include a lock to it is the option. Getting one is easy, but there are things to be done before using it.

The new mailbox with the lock needs to be approved by the postmaster to be able to use it. You cannot install a lock onto an existing contemporary or traditional mailbox.

What Is The Recommended Post Size for My Mailbox?

The post of a mailbox should be no longer than 42” in length. This is because the USPS mandates that a mailbox cannot be higher than 45” off of the ground. You must then take into account the 3” of an average American curb.

How Does A Locking Mailbox Work?

In short, the locking mailbox is similar to the traditional without lock mailbox. The USPS carrier would put in the mail into the income mail door. It is a small opening to ensure that the letter gets into the safe part of the mailbox.

When you need to collect the mail from the mailbox, you need to unlock the secured door to gain access. You can then empty this storage and lock it back.

Is There A Way To Guarantee Anti-Theft?

Sometimes referred to as a secure mailbox, a locking mailbox uses a strong key and lock system to ensure the security of your mail. A locking mailbox typically has a durable steel construction to prevent break-ins and is weatherproof so it can endure the elements.

Can You Lock Your Mailbox?

The reason to get a Locking mailbox is to ensure that your mail is safe from being stolen. Another advantage is to upgrade it to a large one to have the convenience of fitting more letters in the box.

You cannot add the lock to your old mailbox. You need to get a new one with the locking facility and also ensure to get it approved by the postmaster. USPS carriers do not accept the key for the locking mailbox.

They also do not open the mailbox to put in your mail into it. To enable the lock on your mailbox, you need to ensure the mailbox meets the standard features of the traditional mailbox. So with the approval of the postmaster, you can lock it.

Guide to Buying the Best Locking Mailbox

Buying locking mailboxes can be confusing especially with the many brands available on the market. However, it is possible to get the best locking mailbox if you know what you are looking for.

Sometime you might get mail along with the packages from the sender. Hence, it necessary to weigh the product to obtain an estimate of the required shipment fees. To know the exact you need reliable postal scales.

Mailbox Placement

Where you intend to place your new mailbox will determine the model you buy. Consider setting up your inbox at a strategic point that is within sight. Generally, there are two types of locking mailboxes: curbside mailboxes and wall-mounted mailboxes.

Curbside locking mailboxes are installed on a strategic place on your curb. They may even take the original position of your mailbox. According to this source, curb locking mailboxes tend to be bulkier because their solid and sturdy design enables them to last longer and withstand weather conditions.

However, curbside security mailboxes require a post and mounting plate to hold them in position. Hence, factor in this additional cost when shopping for a suitable locking mailbox. On the other hand, wall-mounted mailboxes are easier to install.

They can be mounted on the wall of your house, garage, or the main gate. You need no additional accessories to hold them in place, and they also tend to be smaller compared to curbside mailboxes. It is also easier to place a wall-mounted locking mailbox at a safe place where you can see it.

Mail Type

The type of mail you receive will also determine the kind of security mailbox you need. If you only get small envelopes like utility bills, a compact locking mailbox will do. On the other hand, if you receive bigger packages, like online shipment, a large locking mailbox will suffice. 

Mail Sensitivity

How sensitive the mail you receive determines the level of security you want on a locking mailbox. If new credit cards or any financial bills are sent to your mail, you need a tamper-proof and fortified locking mailbox.

However, if you do not risk losing sensitive information from the mail you receive, then an entry-level locking mailbox would do.

Mail Space

How much space you need in your locking mailbox depends on the frequency of mail you receive. Moreover, if you do travel a lot, you need a security mailbox that will hold all your mail for a while until you get back. Some locking mailboxes can hold several months of mail.

Mailbox Approval

It is required that you notify your postal carrier when you are upgrading to a locking mailbox. A postmaster will have to verify that the new locking mailbox is legitimate for home or business use. Fortunately, most locking mailboxes sold today come with the postmaster’s seal of approval.

Lock Mechanism

Locking mailboxes open by either key or a digital keypad. Your preference should guide you on which locking mechanism to go for. Keypad lock mailboxes are preferable if you tend to lose your keys a lot. A key and lock mailbox, on the other hand, is ideal if you will likely forget your keypad password.

Ready To Buy The Best Locking Mailbox?

The best locking mailbox should meet all your needs as a consumer. There are plenty of locking mailboxes on the market to choose from. The brand or model you go for should not only provide the required security but also provide additional benefits to help manage your mail better.

Do your research first before settling on the locking mailbox to buy. Consider this comprehensive locking mailbox review as a buyer’s guide to getting value for your money.
