Are Mailboxes Magnetic?

Have you ever strolled past a mailbox adorned with magnetic decorations and wondered, “Are mailboxes magnetic?”

Truth is, mailboxes are usually made of materials like steel, aluminium, or plastic, which are not inherently magnetic.

However, there are often magnets on or inside mailboxes used for various purposes, such as holding the door closed or displaying magnetic decorations.

In this quick post, we’ll take a closer look at the materials used to create mailboxes, the role of magnetic add-ons, and the delightful world of magnetic mailbox decor.

Mailbox Materials

The appearance, durability, and, yes, even the magnetic properties of mailboxes depend largely on their material.

Whether a mailbox is post-mounted, wall-mounted, or part of a multi-unit setup, it is worth noting that every mailbox you encounter is typically made of one of these materials.


Steel mailboxes are common in many neighborhoods, and modern options like the Ecco E1 & E2 are particularly loved for their sleek design, durability, and robustness.

However, while steel is magnetic, plain steel mailboxes, especially thinner ones, may not exhibit strong magnetic properties compared to materials like iron.

If you’re looking to decorate a steel mailbox with magnetic accessories, it is best to choose a thicker one because magnets stick better to them than thinner ones.


Aluminum mailboxes are popular for their lightweight and corrosion-resistant qualities. High-quality options like the Supreme Letter Locker provide good security and can hold up to 4-weeks of mail.

Here’s the thing, though. Plain aluminum isn’t magnetic, so you won’t be able to stick magnets on them without a little extra help.

And even at that, aluminum won’t sustain magnetism after you remove the magnet because it is a paramagnetic material with unpaired electrons.


Plastic mailboxes are great at resisting the elements and come in various shapes, sizes, and colors. As you might guess, plain plastic is not magnetic, but the good news is it’s easier to add magnetic features to plastic mailboxes due to their lightweight nature.

For example, you can add a mailbox cover with magnetic strips to your plastic mailbox, beautifying your mail receptacle.


While the USPS has certain restrictions regarding wood, it is a common choice for adding a touch of rustic charm to mailboxes.

Like plastic, wood is typically not magnetic unless mixed with magnetic materials. However, this is not a common practice in mailbox construction.

That’s another way of saying if you’re looking at magnetic decorations on a mailbox and wondering, “Are mailboxes magnetic?” chances are, you’re looking at a metal or modified plastic mailbox and not a wooden mailbox.

Magnetic Mailbox Accessories

If mailboxes are generally not magnetic, how do magnets end up on them? The secret lies in magnetic mailbox additions.

These accessories can include magnetic door latches, address numbers, and various decorative magnets designed to enhance your mailbox’s look.

Here are the common mailbox magnetic accessories that make these mail containers not only boost the functionality of these mail containers but also infuse them with personality and charm.

Magnetic Door Latches

Ever wondered why your mailbox door stays securely closed, even when it’s a non-locking model? It’s thanks to a magnetic door latch.

These trusty little magnets ensure your mail stays safe and protected. When the mailbox door is closed, the magnetic latch holds it in place, preventing any surprises, like your important mail falling out of the mailbox.

Magnetic Address Plaques

With magnetic address plaques or numbers, mail carriers can easily find your mailbox, and visitors can quickly locate your home.

These easy-to-see numbers are not only convenient but also allow you to customize your mailbox with a personal touch. Just slap on these magnetic digits, and your postal carrier will know exactly where to deliver your mail.

Decorative Magnets

Decorative magnets can add character to your residential mailbox. They come in various designs, including seasonal themes, sports teams, animals, and landscapes, and can be easily attached to the mailbox using magnetic strips or adhesive.

Whether you choose a cheerful seasonal design or a quirky figurine ― decorative magnets are a fantastic way to bring a smile to your face as you collect your mail.

There’s more to mailbox décor than meets the eye. Magnetic decorations can turn your mailbox into a canvas for expressing your style and celebrating the seasons.

Here’s how magnetic mailbox decorations work and why they’re a fun addition to any mailbox.

Seasonal and Holiday-Themed Magnets

One of the fantastic things about magnetic mailbox decorations is their versatility. You can easily choose a decoration to match the season or celebrate a holiday.

For instance, you can adorn your mailbox with festive decorations like Christmas trees, snowflakes, or colorful ornaments during the holiday season.

You can use warm autumn leaves décor in the fall. It’s a simple yet effective way to bring the spirit of the season to your mailbox.

Adding a Personal Touch

Decorative magnets are not limited to just holidays; they can be a canvas for expressing your personal style year-round.

Whether you’re a nature lover, sports enthusiast, or someone who appreciates art, there’s a magnetic decoration for you.

You can choose from a wide range of designs, or, if you prefer, you can even paint your mailbox to reflect your individuality.

Easily Change Your Mailbox Décor

The best part of magnetic decorations is that they are a breeze to change and store. When the season changes or you want to switch up your style, you can simply remove one magnet and replace it with another.

You can neatly store the unused decorations until you’re ready to bring them out again.


Are mailboxes magnetic? Not inherently, they are not. However, adding magnetic accessories to a mailbox can enhance its functionality and aesthetics.

Magnets can keep your mailbox door tightly shut, securing your mail. They can also help identify your address and allow you to express your personal style.
