Green or Blue? Picking Your 6x18 Reflective Address Sign

Picture a pizza delivery driver at 7:40 on a December night. Snow is blowing sideways, every mailbox on the road looks the same, and your house number is hiding behind a bush. Somewhere out there a pizza is getting cold. A reflective address sign is the cheapest way to make sure it isn't yours.

This guide is about one specific sign: the 6x18 reflective address sign, available in a green or blue background with white reflective numbers.

What's in the box

Green or blue?

The two colors are the same sign with a different background, so it comes down to taste and surroundings.

Whichever you pick, look at the post and the background behind it. You want the white numbers to pop and the sign to look different from what's around it.

Where to mount it

Put the sign at the point where your driveway meets the road, on the side drivers approach from, facing traffic. Keep it clear of branches, snow piles and mailbox flags. Because the numbers are on both sides, you don't need to worry about the direction a driver is coming from.

Mounting tips

  1. Pick a post that is solid and won't sway in the wind.
  2. Hold the sign against the post and mark the pre-drilled holes.
  3. Use rust-resistant screws or bolts that suit your post material.
  4. Step back to the road and check that it's level and readable from a driving distance.

Why not wait for spring

Evenings are getting darker now that the clocks have changed, and winter storms make house numbers harder to find for delivery drivers and for anyone who needs to find you quickly. The signs are in stock and ship the next business day, and standard shipping is free on U.S. orders over $55. It's a practical gift for a new homeowner, too.
