Sorting by Time Zone with a lookup command

Hello,

Everyday I am constantly creating call lists to reach out to prospects for my company. In my sheets I have the name of the individual/Business and numbers, I have to follow the DNC guidelines and hours I can solicit. With that being said I am trying to maximize my time by calling on est time zone earlier and pacific later. Is there a way I can create a master key where I can list all of the area codes for each time zone and have excel organize them for me?

The entire number is in one cell, is there a formula that can compare the first three numbers in a cell to a master key that then lists which timezone it is in?
