Mandatory 10-Digit Dialing Coming to 406 Area Code

The Federal Communications Commission (FCC) has mandated that10-digit local dialing be adopted for all 3 Rivers customers in the 406 area code (and many others throughout the country) starting July 16, 2022, in order to enable 988 as a new three-digit number to be used nationwide to reach the National Suicide Prevention and Mental Health Crisis Lifeline. Customers must continue to dial 1-800-273-TALK to reach the Lifeline until July 16, 2022. 

This means you will need to change the way you dial local calls.
