Usually only high dollar packages or deliveries to houses with previous lost package claims (a claim made after the package had been scanned as delivered) really require signatures. Otherwise they'll leave the package on the porch or as designated regardless if anyone is home.
Depends on area
If it is , UPS will leave a notice. You can then choose to have it delivered elsewhere.
depends on how carrier sent it or if you have specific instructions; other than that, they may leave it or provide a slip (if it's their final attempt for delivery)
