10 Digit Dialing Transition

There are 37 states and 83 Area Codes that will transition from 7-digit dialing to 10-digit dialing because of the implementation of the 988 access to the National Suicide Prevention Lifeline. If any alarm panels are dialing out seven digits now, they must be re-programed to dial out a ten-digit number which includes the area code plus telephone number.

Such updates or reprogramming must occur between April 24, 2021 and October 24, 2021 (the permissive dialing period).

The mandatory dialing date is October 24, 2021.

No change is needed if the alarm panels are currently dialing out ten-digits, or if they are dialing out a toll-free number (800, 888, 844, etc.) to reach Quick Response.
