Yes, all BLD purchases require a signature at the time of delivery. In order to protect your package, an adult of 21 years or older is required to be present to sign for the package at delivery. This is how we guarantee FedEx has verified the identity of the recipient to avoid package theft. This is verified by a driver's license or military ID that shows your legal age. If you have your package held at a FedEx location, the same age restriction will apply.
Any customer can opt out of this by reaching out to our customer service team prior to your system shipping for a regular all-age signature at delivery.
