Locking Mailbox Basics:

You have already decided a locking mailbox is a logical way to protect your mail and deter identity theft. All that is left is to decide which locking mailbox best suits your needs. Narrow down your selection of locking mailboxes by first determining the type of mailbox you're going to buy and where it will be placed.

Types of Locking Mailboxes

Mailboxes which lock come in two basic styles: a wall mount secure mailbox which attaches to your house, garage, or gate, and a curbside locking mailboxes which is typically on a post near your curb. Occasionally both the wall mount mailboxes and curbside mailboxes are used for commercial use as a drop box.

Placement of Locking Mailboxes

When buying a locking mailbox you must first decide which type will best work for you. If you already have a mailbox on a post near your curb then it is best to simply replace it with a locking mailbox. The US Postal Service must be contacted if you desire to move your mailbox from its location, in particular from the curb to mounting it on your house. Likewise if you have your mailbox attached to your home, you will need postal approval to make a change to a curbside location.

Curbside Locking Mailboxes

All of our locking mailboxes that sit on a post or column at your curbside are US Post Master Approved. Typically the drop slot or mail slot opening that the postal carrier drops the mail into is not locked. The cavity that the mail drops into is the secure area which you will have a key to. It is large enough for typical mail like envelopes and magazines to be easily dropped inside; however a few models have a hopper door which allows larger items to be dropped in such as mail-order prescriptions, boxes of checks, etc. The mail drops down into a securely locked cavity you have access to with a key or by using a keypad. Check out our Locking Drop Box Buyers Guide. Your postal carrier does not need a key. He or she simply opens the delivery door and drops the mail into the secure cavity. The cavities hold from one week to several months’ worth of mail. In the event you will be traveling, you will want a larger mailbox. The average curbside locking mailbox holds 1 to 2 weeks of mail. Retrieving your mail is as simple as turning a key or typing in your code. The retrieval door is typically in the front of the mailbox, however several mailboxes have an option to have this door in the back of the mailbox. This option is called a rear retrieval doorand you will not have to step into the street or curb to retrieve your mail. Yes, a Curbside Locking Mailbox is the type of mailbox I am looking for. To determine which Curbside Locking Mailbox best suits your needs, consider the type of mail you receive, the quantity of mail you receive, and the cost of the mailbox.

Type of Mail

When deciding which curbside mailbox to go with, first analyze what your average mail type is. For instance, if you only receive envelopes and magazines, you will NOT need a larger delivery door or large hopper door. Our Locking Mailbox with Optional Combination Lock will likely fit your needs or possibly the Locking Mailbox with combination and post. However if you have small to medium packages delivered, you may want to consider one of these models: Locking Curbside Mailbox, or the Locking Mailbox with Hopper Door. These styles of locking mailboxes have a hopper door similar to the drop box at your local post office. When you open the door to drop the mail in, the back of the door closes off so someone cannot reach in to take your mail. Once the door is closed it allows the mail to drop down into the secure locking mail area.

Quantity of Mail

Another factor in choosing a secure mailbox is the amount of mail it will hold. On average our curbside mailboxes will hold 1 to 2 weeks, however several models will hold several months of mail. If you travel for weeks at a time you may want to consider our Locking Mailbox with Hopper Door,which allows delivery of small parcels, holds 2 to 3 weeks of mail, and has upgrade options for higher security. The door and lock upgrade is well worth the additional expense for the peace of mind it can give.

Cost of the Mailbox

Finally, the cost of your mailbox is considered. Our average residential locking mailbox costs $185.00, however when you consider the importance of your mail you may want to spend a little more to help insure the security of your mail and identity. Also consider these mailboxes are made of metal and designed to last for many years. A typical lockable mailbox is made with a higher standard than the average non-locking mailbox. Your investment in a highly secure locking mailbox will last for years and in the long run protect you and your family from having your mail stolen and identity stolen.

Locking Mailbox Posts: In Ground or Surface Mounted

Which post do I need? The in ground post goes in the ground, typically cemented in. It has a plate on only the top where you bolt the lockable mailbox to the post. The end without the plate goes in the ground. If you have dirt/grass where you are going to install the post then you will need the in-ground secure mailbox post. The surface mounted mailbox post has a plate on both the top and bottom. The top plate secures the locking mailbox and the bottom plate is bolted to existing cement slab, or side walk. If you have have a side walk or cement where you want to install your mailbox the surface mounted post will work for you. There is also the option to secure your locking mailbox to an existing 4 x 4 wooden post. Typically all curbside mailboxes have pre-drilled holes in the bottom which allow you to secure you mailbox to the steel post. In order to secure your mailbox to a wooden post you simply need secure a 1 x 6 or 2 x 6 to the top of the wooden post. Then secure the mailbox to the 1 x 6 or 2 x 6. We strongly suggest waiting until your mailbox arrives before purchasing any supplies. 

Wall Mounted Locking Mailboxes

A Wall Mounted Mailbox means you do not have your mailbox near your curb or street. In other words you live in a neighborhood where your postal carrier walks from house to house and drops your mail in a box or drop slot attached to your home. Wall Mount Mailboxes are typically easy to install and can be mounted to any surface including siding, brick, stucco, etc. Most, if not all, are attached with two screws. The back of the mailbox that attaches to the wall of your home has two screw holes in it. Simply locate where you would like to attach the mailbox, use a stud finder to locate the studs in the wall, hold the mailbox up, and mark where you need to drill holes. Remove the mailbox, drill your holes, replace the mailbox on the wall, and screw in the screws. You may want to consider using large washers to help distribute the area that the screw holds on to the wall.

However, each of our painted mailboxes are coated with a durable powder coated paint to withstand harsh climates and will look great for years. 

Column Locking Mailboxes

A column mailbox typically means the secure mailbox is encased in brick, stone or stucco giving a more custom look. Most, if not all, of our Curbside Secure Locking Mailboxes can be encased in brick.

Locking Cluster Mailboxes

A cluster mailbox is typically what you would see for an apartment, homeowner associations, or group of condos wanting to share or have a common area to pick up their mail. The mailbox units are also called Cluster Box Units (CBU’s). The units can have as few as 8 individually locked mailboxes or as many as 24 locked boxes. For larger groups of homes typically the numbers CBU’s are spaced throughout the group of homes so each homeowner does not have to walk as far to retrieve his or her mail. The postal carrier will have access to the back door where he or she can open the entire back panel and quickly inset the mail to each individually locked area. Each compartment is assigned to a home and keyed individually. There is also a larger locked area for parcels. The postal carrier can lock a parcel in this area and the key is then put in the individual’s locked area so he or she knows to use the key to retrieve the parcel. A cluster unit mailbox typically comes in numerous color choices and styles, from simple to decorative. The post and a decorative top are the most common upgrades to get a better look.
