Next step

A 705 number tells you where it was issued, not what it is now.

Mobiles, landlines and VoIP lines share area codes, and numbers move between carriers. A live line-type and carrier lookup on every number in your list says which is which, and that decides which calling and texting rules apply. It's in the Email + Phone plan.
