Ask your post office, if they will allow you to use their physical address. I had to sign an authorization for them to receive UPS & FedEx shipments.  Their street address plus your box number (which FedEx/UPS accepts as a suite or apartment number) works. My insurance company (Farmers) uses both addresses - mailing and garage.

The latter is probably because the rate is in part dependent on the physical address, some locales being riskier than others.  Living in an exurban area where mail theft is common, and mail delivery is "rural," I use a PO box for all important mail.
