CHECK IN FASTER Amazon Relay helps truck drivers save time at Amazon Fulfillment and Sort Centers. Use the app to pre-register your loads and get gate passes right on your phone. HOW IT WORKS Download the FREE Amazon Relay app. When picking up or dropping off at Amazon facilities, enter load information to get your Gate Pass in advance. Once you arrive at the gate, simply scan your Gate Pass for fast, easy check in. If you have received an invite code from your carrier, sign in to unlock more features such as notifications if a load gets added or cancelled and detailed instructions about your load. (Contact your motor carrier and ask if they participate in this program).
