My tracking number says my package was delivered but I have not received it.
Occasionally a USPS carrier will scan a package as delivered before it arrives at the final destination. When this happens, the package is usually delivered within the next few business days.
If possible, check with neighbors or the USPS carrier to ask them about your order. You can also call your local USPS post office and ask about a package addressed to you. Here is a link to find your local USPS office.
Keep in mind that carriers sometimes leave packages in a safe, hidden place like on a side porch, around your garage or behind bushes.
