WhitehallProducts 11245 Nite Bright Ironwork Reflective Address Post Sign, Black/White

Q: How many of each number is included with this kit?

Six of each digit were included in my kit.

Q: I have duplicate numbers in my address. Does this come with multiple copies of numbers?

It includes six of each number but beware mine was missing its hardware and I read other reviews of people saying the same thing and I’m not talking hardware to mount it on a wall I mean the hardware just to put it together as shown in the picture.

Q: Is the sign constructed in a way that I could attach it to a tree instead of the post that comes with it?

Yes! I think it looked better at our place (single unit condo) when we attached it to the post at our front porch. And more secure too. I couldn't post a picture because it's "Not supported"- whatever that means!
