Postal Letter

What does arrival at unit mean on the USPS tracking info page?

I have a package that should be delivered today. On the USPS tracking page after I enter my trackin info it states that at 7:41 my package "arrival at unit" does this mean that it has arrived at the post office? If so will I receive my package today?

1. If the unit location is in your town, I would say you should expect the delivery today.
2. The "unit" is the postal facility. Normally that kind of phrase would mean that the item is at your local post office or the district office and will be at your local office for delivery w/i 24 hours.
