Our booths do require a signature to be dropped off. When FedEx makes an attempt, they typically leave a ‘door tag’ at the point of entry, which is essentially like a big sticky note. This tag explains the missed delivery, and also allows the recipient the option to sign it and leave it on the door, effectively giving FedEx permission to drop it off  on the next delivery attempt without a recipient present. If enough attempts are missed, they will hold the package at the local hub for up to 10 days (it is available for pick up in this time!) before returning the shipment to us.
