9-1-1 ECC 

Bill Ferretti, Director

The Montgomery County, Maryland Police Department 9-1-1 Emergency Communications Center (9-1-1 ECC) is a nationally recognized center, the largest in Maryland, and one of the 50 largest in the United States.

Montgomery County inaugurated a new 9-1-1 Center in July 2003 incorporating all new state-of-the-art technology systems. The equipment includes: a 9-1-1 Emergency and Non-Emergency Telephone system, a Computer Aided Dispatch system, an 800 MHz radio system, a Graphical Information (mapping) System, an Automatic Vehicle Location via Global Position Satellite system, a Mobile Data Terminal system, and other ancillary systems.

Personnel of the 9-1-1 ECC are the “1st of the First Responders” with whom the public has contact in times of emergency.

Non-Emergency Line – 301-279-8000


Montgomery County residents Make the Right Call by using:

  • 9-1-1 only for emergencies,
  • 301-279-8000 only to report non-emergencies, and
  • 3-1-1 for general Montgomery County government information.

Having a better understanding of when to call each of these three important phone numbers will help ensure that your specific need is most effectively met.
