While most smart devices already include the numbers, it will soon be mandatory to dial all ten digits when calling any local phone number.
South Dakota Public Utilities Commission Chairman Chris Nelson says the move is to make way for a national suicide hotline.
Nelson says those three numbers have to be able to stand alone.
Nelson says the change to ten digits will start soon.
Starting in July of 2022, calling 988 will route your call to the National Suicide Prevention and Mental Health Crisis Lifeline.
