So because 248/947 are Oakland County overlay area codes, do you always have to call the 1+Area Code+7 digits... even if the number you are dialing is the same area code that you are calling from ??...
Yes, 10-digit dialing is now required, even if you and the called party are both in the same area code/NPA. The prefix 1 is no longer required when placing the call from cell phones.
