Is a 224 call a scam?
An area code tells you where a number was first assigned, not where the caller is. Mobile numbers keep their area code when people move, and internet (VoIP) numbers can be picked in any area code — so a 224 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 224 number to people in Illinois because a local-looking call is more likely to be answered. If a 224 call claims to be your bank, the IRS or a delivery company, hang up and call the official number yourself.
About area code 224
224 entered service on January 5, 2002, as an overlay on 847, which had run short of numbers.
It is part of the 224/847 overlay: the codes cover the same area, and a new line there can be given a number in any of them. Two neighbours — or two phones in one household — can have different area codes. That is also why local calls need the full ten digits.
