The robo calls use your area code and exchange then 4 random numbers. No way to block that. The random numbers are new every call.

With the call blocker I use, I can block by using the area code, exchange & #### which will block ANY number starting with the same numbers as the area code/exchange. I can also block just by area code. There is the option to change from the default setting (allows all calls except those you block) so my blocker is currently set up to do the opposite - block ALL numbers except those I invite. My area code is invited .... so for these new scammer calls, I can then block them using the exchange.
