Can I drop a letter on USPS blue box on Sunday?

Question

I know there is no collection on Sunday and it will be collected on Monday, but does the blue box always have the plastic inside that mailman collects?
Thanks.

Answer 1

Yes. However there was one time my management company either didn't get my rent check, or got it late, when I did it like that. So now I always walk in there, or give it to a mail carrier.

Answer 2

Of course it does Jesus ******* Christ. Use your brain.

Answer 3

Why does it matter what the inside of the box is made of? Good grief!

Answer 4

Yes you can drop it into the box, it will just sit there until it's collected.

Answer 5

Yes. However, there is a slight risk that someone might break into the box and steal your letter.

Answer 6

Yes. When a tray is taken out of the box, a new tray is put in the box.

Answer 7

yes but they won't pick it up til Monday if there's no holiday

Answer 8

yes you can mail your letter any time.
