Verizon now requires we include the area code on all calls

I got a message from Verizon, my cellular provider, that starting on 10/24/21, I must include the area code on all calls I make, including local calls. I don’t know why Verizon can’t make it easier and simply assume that if I’m making a call and I don’t include the area code, I’m trying to dial locally, but that’s on Verizon, not Apple. My question is, how does this work with the Apple address book? Do I have to go in and add an area code on all local entries in the address book or is there some setting that can automate this?
