Tips on Choosing

When choosing a security mailbox you’ll want to purchase something that works well for your needs.

USPS approved

You want to make sure you get a USPS-approved mailbox so you know that it will work well for your mailman too. If you’re unsure about USPS-approved boxes, you can check out their website for minimum standards. Your mailbox should be easy for you to use.

Easy to Use

If you don’t have the full function of both hands, you will need a mailbox that you can easily unlock and open with a single hand. In further disability cases, you might think about getting a mailbox you can mount lower for wheelchair access or one that opens at eye level so you don’t have to worry about kneeling. You might also need a box that is closer to the front door instead of out by the road.


Choosing a durable locking mailbox is important. The mailbox for you will not have a place for mail to escape, will not fall apart, and the box will be big enough to place your mail in but not your hand.


Make sure you have enough keys and make sure you get the right-sized box for your mailing needs.

Factors to Consider

Size of mail:

Consider the size of the mail you plan on receiving in this locking box, if it’s packages, parcels, or larger envelopes, you will need a box that is large enough to receive those types of products. Keep in mind you need a functional box so you can retrieve the packages from the box without damaging them as well.

Type of box:

Do you have specific types of incoming mail such as rent checks, flyers, or magazines? You need a mailbox that can also function as a drop box.


Do you have specific types of incoming mail such as rent checks, flyers, or magazines? You need a mailbox that can also function as a drop box.


Think about where you need the mailbox placed. Do you need it to be a stand-alone box or something that can be mounted? Do you need to place it inside or outside? Interior wall mailboxes can be pretty small and may not have to be heavy-duty like the ones you would place outside your home.

They evaluated what their needs were and they made a choice. You might find someone who has needs similar to yours and if their mailbox purchase worked well for them you might want to purchase the same locking mailbox.


What is the recommended post size?

Post size depends on your needs. You want to be somewhat flush with your neighbors if they have a roadside mailbox as well. Most of the mailboxes we reviewed recommended a 4×4 post for mounting, but if you use an inground post, you will need some length. Make sure your inground post has a cemented base so your mailbox doesn’t float or fly away. The type of posts you’ll want to use include plastic, wood, or steel.

What if I build my mailbox?

Building your mailbox is fine, but you have to make sure you have a mailbox that meets USPS standards. Meeting the USPS requirements will cost you a great deal of time and money. You can find the required specifications on the USPS website. If you need help building or installing your mailbox you can find tons of examples online.

Is there a way to guarantee anti-theft?

No. The truth is, if someone wants to get into your box they will find a way to pry it open. Locked mailboxes are there to keep the average thief from getting in there and quickly taking your mail. Some thieves will roam at night with tools.

If there is a high level of mailbox theft in your area you might want to report any incidents to the local police department for extra surveillance. A good tip to avoid a chance of your mailbox failing is to pull your mail as soon as it arrives. Don’t leave it sitting overnight or for weeks at a time.

Is there a weatherproof mailbox?

Manufacturers have gone to great lengths to secure some of the mailboxes, but in some cases, a tiny opening still makes a big difference. If you like a particular box but you can readily see it may have an issue with rain consider whether or not you can add something to the mailbox to prevent your mail from getting wet.
