Sorry I don't know what board to post this on. What exactly does "Arrival at Unit" mean using the Postal Service's delivery confirmation tracker? It says it got to my town at 2:04 PM. Does that mean that it's at the post office now waiting to be sent to my house tomorrow, or does it mean that it supposedly arrived at my house at 2:04? HELP! ...then feel free to move or delete the topic.
If they tried to deliver it at your house it would say "Delivery attempt made." Right now it is at one of your local mail handling buildings and a delivery attempt at your house is imminent.
