What must a new tenant do, RE: mail delivered to the previous tenant?

That might work. USPS has this handy COA online form, we’ll put in a change of address for everybody in the neighborhood and have the whole block delivered here! Beautiful!

In all seriousness - my letter carrier told me a common mistake when Susie or Johnnie (finally) moves out of the house, the change of address form has a “Individual” or “Family” block, and for some reason they will check the wrong block - guess what happens? Yeah, the automated sorting machines start forwarding ALL the mail to wherever Susie or Johnnie is living.

I have been writing Addressee Unknown.
Is that okay?

It’s not correct, but it’ll probably work. The definitive answer straight from USPS was up in post #2. You might look at that.

What if the letter is from 1955 and the DeLorean is in the shop?

We have a letter we received a couple of years ago now that was returned to the original sender’s address, which is, in fact, this house. The address it was mailed to appears to have been some sort of summer camp in New York State which no longer exists.

The only postage marks are outgoing from this city in 1955, a 1955 mark in Philadelphia, and then a Canada Post sticker in 2022 returning it to us.

We haven’t opened it, but clearly putting it back into a mailbox would be useless.

I like to imagine it’s just a mother writing to her daughter at summer camp where she was either a camper or employee. The intended recipient’s name is female and the sender’s name is a different first initial than the male homeowners name on our history paperwork.

The family name is, unfortunately , common.

I’d love to get this letter to the intended recipient.

I see mail for several previous tenants in my Informed Delivery, but most doesn’t get delivered to the box. There was one tax form from a credit card company that arrived and looked important. I called the credit card company and told them the person (a minor) was not at this address. They told me to write “addressee unknown,” which I did. It showed up in my box again. I blacked out the address and arrowed to the return address. It returned. I put it in another envelope and sent it to the credit card company. I’m willing to do that with things that are important, at least a few times.

A package of medication was autoshipped to the previous tenant. I dropped it at their realtor’s office nearby. I’d want someone to do the same for me. We got a smiley face note on the front door from the previous tenant, who doesn’t speak much English.
