You misunderstand slightly. All the calls from the area code matching your phone number are more likely to be spam (spammers matching you to appear legit). So unless you call people in that particular area, you won't be matching their area code, so you won't look like a spammer. And unless you happen to know a lot of people in that area, you won't get calls from that area that appear to be spam.

You're misunderstanding them too, I suspect. One could equally assume that a call coming from an area code they've never been to, 5 states away is spam - so this trick works if you do not make a lot of calls.

Not equally. I have an area code from the opposite coast. If I get a call from that area code, it is 100% spam. Spammers just love outing themselves by spoofing the same area code of the person they are calling.

A call from any other area code is only 30% chance of being spam.
