They could possibly flag it and show up when its supposed to be delivered, but you can always just not open the door, you are not required to (please review your rights as well) depending on your state, I would use the search bar and search US welfare checks for other's experience, as I know I've seen people post about it. I feel like it could also come down to where you live in the US. Does where you live have a lot of extra bodies in the PD for welfare checks?? For example, my cities police department is so overrun by murders etc that we no longer even have a narcotics department and on the back of parking tickets is a "WE ARE HIRING" bs. My city ain't checking on me when I choose to order it.
