Updated 6/24/2019 5:25:53 PM by Comcast Expert


Short code dialing, also known as N11, provides you with quick and easy access to emergency services, local community resources, utilities, traffic information, and other useful services. Although Comcast equipment is already capable of supporting Short Code dialing, any third party equipment, such as PBX systems, may need additional programming for compatibility. Please work directly with your equipment provider to ensure that short code access is enabled for your business. Please see a list below of all the codes supported by Comcast if enabled by your county/state.

911 Emergency Calls

In most major cities, emergency police, fire and medical services can be reached by dialing 911. Enhanced 911 (E911) automatically provides the emergency service with your telephone number and location when you dial 911 from your business phone. Comcast Business Voice and VoiceEdge Select services may have E911 limitations as specified below:

  • In order for your 911 calls to be properly directed to emergency services, Comcast must have your correct service address. If you move your Comcast Voice service to a different address without Comcast approval, 911 calls may be directed to the wrong emergency authority, may transmit the wrong address and/or Comcast Voice service (including 911) may fail altogether.

  • Comcast Business Voice and VoiceEdge Select services use the electrical power in your office. If there is an electrical power outage, 911 calling may be interrupted if the battery backup in the associated multimedia terminal adapter is not installed, fails or is exhausted after several hours.

  • Calls, including calls to 911, may or may not be completed if there is a problem with network facilities, including network congestion, network/ equipment/power failure or other technical problems.

  • Prior to changing your address or moving your service, or if you have any 911-related questions, please call Business Customer Support at 1-800-391-3000. Comcast will need several business days to update your new service address in the E911 system.
