May I recommend reading

and
https://telemarketing.donotcall.gov

For more than 5 area codes, you will have to pay to access the data - it
seems you can download number lists then to compare to your customers
phone numbers list. 5 or less area codes are free.

If you call nationwide prepare to pay some 17k$ for the lists for all
area codes.
