The 401 area code is Rhode Island.
We have had the 401 area code blocked for over a year.
Their call was blocked BEFORE they robodialed our office. Our phones did not ring and our office was not disturbed.
These criminals can change phone numbers all they like but if they call from the 401 area code, they are BLOCKED.
Please purchase a call blocking phone or a blocking device that can block entire area codes - we have both.
BTW - each area code has the POTENTIAL for 8,000,000 - 10,000,000 phone numbers!
