For starters, if you are dealing with a USPS/FedEx SmartPost "says delivered in mailbox but no package is physically there" situation you’re going to want to do a couple of things before reaching out to the post office themselves.
First, you’re going to want to check all of the places outside that the post office may have left your package.
A lot of times packages can be delivered by someone on your mail route that isn’t the “regular” mail delivery person, and they may not know that your packages should be left next to the garage, on your front steps, just below your mailbox, etc. the way that your regular mail delivery person takes care of things.
Plenty of people find that even though tracking says delivered but no package was found in their mailbox, it's only because the package itself was left at another doorstep, in the bushes, or set somewhere that they weren’t expecting.
It’s always a good idea to check no matter what.
If, however, you didn’t receive your package from USPS/FedEx SmartPost and can 100% verify that it is not on your property – even though the tracking information says that it was delivered – you’re going to want to reach out to the post office or FedEx ASAP.
The overwhelming majority of missing package situations usually involve packages or parcels that were scanned but not put on the vehicles for delivery, that “slip through the cracks” and just weren’t delivered on time, or that simply were overlooked or not delivered in a timely manner for one reason or another. Lastly, sometimes mail just gets left inside of the delivery vehicles even though they scanned it as delivered earlier.
We ask that you wait a few days to see if your package is delivered before filing a claim. If after 5 business days, your package still hasn't arrived, please call us for additional assistance.
