A package sent to my UPS box was addressed to a PO box and has been tracked to the Santa Rosa Post Office. How can I go about locating it?

I would recommend going into their location to speak with them about the issue. Make sure to bring ID for proof.

Speak with the post master or he's ever in charge. Anybody at the counter will build help you too but don't call them that's a waste of time if you know it's at the main post office office going person Go in person during regular business hours
