"Missent" means that the first sort facility put the package in the wrong bin based on the zip code.
After that the address is not looked at until it arrives at the local Post Office.
"Arrival at unit" means the local Post Office, not the addressee.
So the local Post Office realized the mistake and probably now is rerouted.
For sure it was not delivered to a wrong person.
Thank you. I feel relieved now. ![Wink ;)](https://www.playingcardforum.com/Smileys/aaron/wink.gif)
You are welcome.
Another thing is that Registered Mail, usually moves slower in the US, because the extra handling they put in.( I talk with a Postmaster, about a year ago, and he said that all Registered Mail is stored in a different area under a lock)
I'm confident that the package will show up next week.
As a side note: If you see that it's no movement on your package by checking your tracking number, you can inquire e-mail updates on the USPS website.Usually that shakes the package off the limbo in the system.
It worked out five out off six times when I was thinking the package was lost(10 days+ on a 2-4 days estimated delivery time).
Sadly, the USPS sometimes is loosing packages...but that is very rare...in three years, sending hundreds of packages a year, I've experienced only 3 missent, 1 damaged and none lost packages.
Hope that helps and everything is going to be fine!
