The details
Built for the post at the end of your driveway
A slim 18" x 3.5" acrylic plaque that mounts flat to a 4x4 post, a mailbox or a wall. The reflective finish uses the same 3M sheeting found on road signs, so deliveries and emergency responders find you after dark.
Number sizing adjusts to how many digits you have, so the address always fills the plaque cleanly. Two-pack option covers both sides of a post.

Why it lasts
Built to outlast the house paint
Cast acrylic and PVC don't rust, rot or peel. That's why we use them instead of the materials most address signs are made from.
0.25" matte finished cast acrylic backer with 0.125" cast acrylic characters — UV-stable color through the material, chemically welded, not glued on.
Compared to typical alternatives
- vs. metal
- Aluminum and steel signs oxidize, streak rust down siding and chip at the edges once the powder coat is scratched.
- vs. wood
- Wood swells, splits and needs re-sealing every couple of seasons. Acrylic ignores freeze-thaw cycles entirely.
- vs. vinyl
- Printed vinyl decals fade, curl and lift within a season or two. Our characters are solid material, so the color can't wear off.
Installation guide
Installing your acrylic address sign
Sized for a 4x4 post, mailbox or narrow wall column. Mounts with two fasteners and stays put through freeze-thaw seasons.
- 1
Choose the face
Mount on the side of the post or mailbox that faces oncoming traffic, or on a wall column beside the door.
- 2
Mark the holes
Hold the sign level in position and mark through the pre-drilled mounting holes.
- 3
Drill pilot holes
Drill pilot holes for wood posts, or use anchors for masonry and hollow mailbox panels.
- 4
Fasten and check
Drive the included screws until snug, then step back to the street and confirm it reads clearly.
Installer tips
- — Mount at 3.5–4 ft so it clears snow banks in winter.
- — Reflective versions light up under headlights at night.
- — Check fasteners once a season on posts that move with frost.

Our sign was everything we wanted and more! Beautiful craftsmanship, flawless design, and the shipping was incredibly fast, despite it being holiday season. It matches perfectly with our newly built home!! It truly is the perfect finishing touch!!

Premium Large Address Sign (Black 20 Inch Vertical)
Exactly what I've been looking for! I did the two hooks attached on the back and it was easy to hang. I previously had a wooden one that did not stand up to the weather (from a different seller) and I like the pvc material of this one and the design is nice. I also liked the fact that the numbers lay flat on the backboard that way under the porch light you don't get a shadow effect.

My first sign was damaged by shipping and I emailed and received another sign right away, with great customer service. The product (sign) itself is awesome and you can see it well from the road. I will be honest and I am not a big fan of the D hanger on the back as the sign moves easily with the wind, other than that it is an awesome product.

We love our new house number and it looks great on our carport/balcony. The sign looks like it will last for many years and we love the design. Wish there was a lighted version…I'm buying if you make one!

Premium Large Address Sign (Black 20 Inch Vertical)
Came as ordered & great quality! Worked well for covering over where old street numbers left their mark. White background makes numbers much more visible from the street. Just what we needed....thanks!

The door number sign matched the description, looks great and arrived very quickly after I placed my order! I used 10x2" screws to install it in the pre-drilled holes.
