You do realize that you are blocking the entire area of DC right? 202 is the legitimate area code for DC. If i blocked it my sister couldn't call me. me giving any kind of advice if you have no clue what you're talking about
Good call blockers & call blocking apps. will have the ability to allow certain numbers through from blocked area codes. Sometimes called "White lists". I have several area codes blocked on my personal phones. 202 is definitely one of them. The people I want to speak to from DC are entered in to those "White lists". All other calls from that area code go straight to VM. When recognized as fraudulent, a callers number will go on a "Black list". Meaning that the call will be refused & will not even go to VM. Basically the caller will be immediately hung up on.
Call blockers are indispensable. Frauds & scammers hate them. Real people can no longer live without them.
Be Safe. Be Aware.
