ONLYKXY Silver House Numbers 0-9 Stainless Steel Garden Door Mailbox Decor Number Sign 2inch Modern Hollow Street Address Number Sticker for Apartment Hotel Building Room Office Brushed Number Sign

A compact, modern way to label mailboxes, rooms, and garden gear

I picked up the ONLYKXY stainless steel house numbers to refresh a tired-looking mailbox and label a couple of utility covers in my yard. This is a small-format set—each digit is roughly 2 inches tall with a hollow, modern design—and it’s aimed more at mailboxes and room doors than big, street-facing house numbers. After a few weeks of use outdoors and indoors, here’s how they performed.

What you actually get

The set includes one of each number from 0–9 and a small packet of matching screws—two screws per digit. That’s enough to create any single-digit label out of the box. For multi-digit addresses that repeat a number, you’ll need more than one set. My house number includes a repeated 3, so I bought a second package to complete the sequence on the mailbox and had leftovers for other labeling jobs.

There’s no adhesive backing, templates, or mounting anchors included. If you plan to mount on metal, plastic, or wood, the supplied screws are sufficient. For masonry or stucco, you’ll want anchors and a masonry bit.

Design and build quality

The numbers are cut from stainless steel with a brushed silver finish. The hollow, sans-serif style reads clean and modern without being flashy. On my black mailbox door, the contrast is excellent, and the brushed surface hides fingerprints and minor scuffs. The edges on my set were cleanly finished—no burrs or sharp corners—and the cutouts are consistent across digits, so the font looks cohesive when the numbers are lined up.

At 1.96 inches high by about 1.25 inches wide, these are small. That’s perfect for a mailbox face, an office door plaque, a storage cabinet, or a garden marker. It’s not a substitute for code-compliant house numbers; many municipalities require 4-inch or larger numerals that are visible from the street. Consider these “close-up” identifiers.

Because of the hollow design, the digits have a bit less visual weight than solid numbers of the same size. On dark backgrounds, they pop nicely. On light siding or brushed steel, they can get lost. If you’re mounting on a light surface, a dark backer plate or contrasting stripe behind them helps.

Installation: quick and tidy if you prep

I installed the numbers on three surfaces: a steel mailbox door, a plastic utility box cover, and a cedar fence slat. Here’s what worked best across all three:

• Plan your layout. I ran a strip of painter’s tape across the mounting surface, used a level to straighten it, and marked the centerlines and hole positions on the tape. This avoids stray pencil marks and gives you a crisp baseline.

• Pre-drill your holes. The digits have small clearance holes that align well with the included screws. For metal, I used a center punch to keep the bit from wandering, then drilled pilot holes slightly smaller than the screw shank. On plastic and softwood, a small pilot hole prevents splitting and reduces the chance of overtightening.

• Hand-tighten the screws. The provided screws are small and match the finish. I found a simple screwdriver gave me better control than a drill/driver and avoided marring the brushed surface. Snug them down until the number sits flush; don’t crank them, especially in plastic.

• Mind your orientation. The 6 and 9 are distinct, but it’s still easy to flip a digit when you’re working fast. A quick dry-fit saves a re-do.

The whole mailbox job—measuring, marking, drilling, and fastening three digits—took about 15 minutes. The numbers sit flat against the surface and don’t wiggle once tightened. There’s no adhesive to fail in heat or humidity, which I prefer for outdoor use.

Day-to-day performance and durability

Outdoors, the stainless steel has held up well to sun and a couple of heavy rains. I haven’t seen any discoloration, lifting, or rust. The screws are also stainless, so there’s no odd galvanic reaction with the digits. The brushed finish sheds dust and water spots better than polished steel, and a quick wipe brings back the sheen.

Legibility at typical viewing distances is good for what these are: small identifiers. From the curb, 2-inch hollow numbers aren’t what you want; from the sidewalk, driveway, or building hallway, they’re easy to read. On the mailbox, delivery drivers can’t miss them, and they coordinate with the rest of the hardware without looking bulky.

I also used a couple of digits to label sprinkler valve covers—an unconventional use, but the small size and screw-mounted design work well for that. They don’t snag, and they’ve withstood lawn watering with no sign of tarnish.

Where they make sense (and where they don’t)

These numbers shine in a few specific scenarios:

• Mailboxes and mailbox posts
• Apartment and office doors
• Cabinets, lockers, and storage
• Garden markers and utility covers
• Indoor signage where a modern, minimal look is desired

They’re less suitable for:

• Primary house numbers meant to be seen from the street
• Low-contrast backgrounds (unless you add a contrasting back plate)
• Masonry surfaces without additional anchors

If you need night visibility, note that the numbers themselves are not reflective. You can pair them with a reflective strip or plate behind them if visibility after dark matters, but out of the box, they rely on ambient light.

Fit and finish details worth noting

• Consistency: The digits are consistent in thickness and finish, so multi-digit sequences look uniform. Spacing relies on your installation; a measuring tape or a simple cardboard spacer helps keep kerning even.

• Hardware: The included screws match the finish and are fine for thin material. If you’re mounting into thick hardwood or need to span a gap, you may want longer screws.

• Packaging: Everything arrived in good shape without scratches or dents. The finish was clean, with no residue that needed polishing before install.

• Cleanability: The brushed surface hides micro-scratches well and is easy to wipe clean with a damp cloth.

What could be better

• Only one of each digit: It’s a common limitation with small number sets, but it bears mentioning—you’ll likely need multiple sets to handle duplicates in most addresses.

• No template or adhesive option: A paper drilling template would make layout even faster, and some users might prefer a peel-and-stick option for temporary installs. As is, you’re entirely in the screw-mount camp.

• Small size limits versatility: I’d love to see a matching 4-inch set in the same hollow style for consistent branding between a house face and a mailbox.

• Contrast can suffer on light backgrounds: A black or bronze finish variant would help in those situations.

Practical tips

• If you’re mounting on metal, a step bit makes cleaner holes with less risk of tearing thin sheet metal.

• For perfect alignment, measure from a fixed edge (top of the mailbox door, door jamb, or panel seam) rather than relying on eyeballing.

• On plastic, stop tightening as soon as the number sits flush—the screws bite quickly.

• If you need nighttime visibility, add a reflective strip behind the numbers before you screw them down.

Verdict

The ONLYKXY stainless steel numbers are a simple, well-made solution for small-format labeling. They’re easy to install, look much more refined than stick-on vinyl, and have held up well outdoors in sun and rain. The modern hollow design brings a subtle update to a mailbox or door without shouting for attention, and the brushed stainless finish plays nicely with most exterior hardware.

They’re not a one-size-fits-all answer. The 2-inch size isn’t meant for street-visible addresses, and the single set of digits means you’ll likely buy two sets for most multi-digit numbers. There’s no template or anchors, so you’ll need a drill and a few minutes of care to get a tidy installation.

Would I recommend them? Yes—for mailboxes, room doors, cabinets, and other close-range applications where you want a clean, durable, and modern look at a small scale. They’re affordable, genuinely stainless, and thoughtfully finished. If your primary need is curbside visibility or high-contrast marking on a light surface, look for a larger size or consider pairing these with a contrasting back plate. Otherwise, these little numbers punch above their size.
