The majority of spam calls come from the same area code as my phone number, but its not the area code that I live in. I'd love this feature to be area code specific - it would give the granularity I need to block spam but allow for unknown numbers from where I now live.

Number Shield on iOS will allow you to block all calls beginning in an area code, but lets through any numbers in your contact list.
