I had this problem as well. I used to live in an apartment complex with a key entry that UPS, USPS, and FedEx had access to, but not Amazon. I never knew when they were going to arrive and they kept saying that they tried but couldn't deliver the package (we didn't have a code, only key entry). Since I couldn't guarantee what carrier would be used, I eventually had to use Amazon Locker only. I live in a house now and no longer have this problem.
