I sent my passport in to be renewed January 11th, priority, and was told it would be scheduled to get to Philadelphia on the 13th.

I have the tracking number, and as of January 13th at 4am, it just says in transit to destination (with expected delivery data of January 13th.) Is it possible it did get delivered, but since its to a PO box, it just didn't get scanned? It was last scanned here in Colorado on the 11th, so nothing east of here. My check hasn't been cashed yet.
