USPS Delivery Problem

[norcalcamaro]

Just got home around 8pm pacific & a package I was expecting was not here. Checked the tracking & it says notice left. There was no notice left anywhere. I tried calling the PO but they closed at 7:30. Wondering if I am going to have a problem trying to pick up the package at the post office with no notice of attempeted delivery?
I was planning on bringing my id & the tracking numbers. Anyone have this happen before? I am wondering if I should just have them try to redeliver so I can get the attempted delivery notice so I can at least bring that in to the PO so I can pick up the package.
