Post wrong address - return to sender!

FirstIn

Folks,
I'm in C'land and quite often I receive post addressed to my house but for someone else, i.e someone I have never heard of. Maybe this happens to you guys also.

Anyways, if there's a return address I do send the letter/card back.

This time I have a letter, sent from Alicante Espana and I can't for the life of me make out the return address. So do I

1: Wander round all houses with the same number as I have in Wood, Court, etc etc hoping to find the right person.
2: Fire the name up here of the intended recipient and hope someone will know the person and PM the proper address.
3: Make a stab at the return address and hope it makes it way back, with a note enclosed saying please phone the recipient and get the right address.

What do you think?

So you are opening other people's post? The correct action is mark it unknown at this address and post it. It is the post office's job to return it if possible, and they are legally allowed open it.

To be clear I don't open it. When I say a note enclosed , I refer to a note in the envelope I send back.

Thanks for the advice, I'll fire it back to the post office.

Put a note on it

"not at this address" and stick it in the postbox

Just mark it as "unknown at this address" and pop it back in the post. No stamp or anything. That's all you're expected to do.
