Phone number is so our couriers can call the pickup or delivery contact directly should the need arise. It helps to get the job done more efficiently rather than having them call Gophr HQ and Gophr HQ calling you. We also ask for the email address so they can be sent a link to track the delivery live, much like you can once you book. Again, this is so they know when the courier is arriving so it speeds up the process of delivery. Should you not want the person in question to receive a tracking link simply leave the email field blank.
