USPS “Arrived at Unit” — what it actually means
It's at your destination post office. "Unit" = your local station. Out-for-delivery is usually the next morning.
Why packages get stuck here
- The unit's morning sort volume
- Carrier capacity — occasionally bumps to next day
How long it usually lasts: Typically next delivery day.
What to actually do
- You're at the finish line
- If the unit has it 2+ days with no movement, call your local station directly — the 800 line sees nothing useful
