We provide delivery services and we store or register the addresses of people on our system in a way that addresses are linked or related to phone numbers. I would like to merge those to question?
Would you like us to contact you on the number you are calling from?
Would you like the delivery guy to arrive at the address that's registered with the phone number you're calling from?
I came up with this but I'm not sure if that's the shortest and correct question :
Are delivery and contact related to this number?
