Locking Mailbox Basics

Keeping your mailbox locked will protect your identity and your mail. There are many locking mailboxes available so choosing the right one for you is easy. It’s important to consider the type and location of your locking mailbox before you buy one.

Types of Locking Mailboxes

If you live on the curbside, the locking mailbox is usually fixed to a nearby post. If it’s mounted on your house, garage, or gate, you can easily latch it. Some commercial mailboxes are mounted on walls and some are curbside.

Placement of Locking Mailboxes

A suitable locking mailbox should be selected first, based on your requirements. You can replace your old mailbox with a locking one if you have one already on the curb. Changing the address of your mailbox requires contacting the US Postal Service. Postal Service permission is required to move a mailbox curbside attached to your home.

Curbside Locking Mailboxes

There will be a locking mailbox installed on a column or a post at your curbside that has been approved by the US Post Office. The mail slots where mail carriers drop off their packages are usually not locked. The mailbox where your mail will be kept will require a key to open. Many models include hopper doors that allow larger items to be dropped in, such as prescriptions from mail-order pharmacies and boxed checks. There is enough space for some magazines, even though it cannot fit typical mail or envelopes. You open the lock on the cavity with the key or keypad.

Providing the postman with a key is unnecessary. Open the delivery door and place the mail into the secure cavity. Each compartment will hold mail for several months. Your mailbox will need to be larger when you travel. Typically, a locked mailbox at the curbside can hold one or two weeks’ worth of mail.

Input your code or turn the key to retrieve your mail. Most mailboxes are accessible through a front entry, although some have a backdoor option. Due to the rear retrieval door, you do not have to step into the street to get your mail.

My preferred mailbox type is the curbside locking mailbox. Curbside locking mailboxes that fit your needs in terms of mailing patterns, cost, and volume of mail are what you should look for.

Type of Mail Deposited

You should first determine what type of curbside mailbox you prefer by analyzing the most common mail you receive. For those who receive only envelopes and magazines, SM7 mailboxes with Post or locking mailboxes with combination and Post would be a good fit for your needs. The following models would be a better choice if you have small to medium packages: Lockable Curbside Mailbox or Lockable Mailbox with Hopper Door. Locking mailboxes like this one have hopper doors similar to post office drop boxes. Mail can be dropped into the mailbox by opening the door, but the back closes to prevent people from reaching in from behind and taking it. After the mailbox door is shut, the mail can fall into the lockbox.

Quantity of Mail

A secure mailbox must be able to store a sufficient amount of mail. A curbside mailbox holds one or two weeks of mail on average, there are several models available that hold up to six months. The Locking Mailbox with Hopper Door can hold up to three weeks’ worth of mail, allowing travelers to keep the mail while traveling. It can also be upgraded for higher security. An upgrade to your door and lock can bring you peace of mind.

Cost of the Mailbox

In addition, we take into account the cost of your mailbox. If you are considering buying a lockable mailbox for your residence, however, you may want to spend a bit more for the extra security. In addition, metal mailboxes are likely to last for a long time. A lockable mailbox generally costs more than one that does not lock. Your mail and your identity will be protected for years to come with a secure locking mailbox.

Do all buildings have keys for the mailmen?

Each mailpiece is delivered to its destination by thousands of USPS employees across the country. Because post office drivers are government-employed, they can enter offices, schools, and residences with a master key.
