Custom Field to capture "Sales Area" based on Account ZIP

Hey dev com...

Looking for the best solution to populate a field based on the Account State/ZIP.
Maybe a formula field with a CASE statement? Maybe a workflow? Process Builder?

For example;   If Account Billing State = MI and Account Billing PostalCode starts with 465 or 466 or 467 or 434, then label the field "Great  Lakes" sales area.

If you have all these rules, then a formula is a possibility -  all formula has limitations such as 5000 chars so if that is not a problem then you are good.  Otherwise, workflow, process builder, etc are good alternatives based on your requirements and whether one or another have restrictions.
