If you would like any documents, information, or materials on this website translated into another language, please send an email with the document name and language information to safetylanguageaccess@denvergov.org

Denver’s 9-1-1 Communications Center is staffed by public safety professionals who are trained to answer 9-1-1 emergency and non-emergency telephone calls, as well as dispatch police, fire and paramedic resources. Our dedicated Emergency Call Takers gather critical information from callers and send the information via computer to police, fire and or paramedic dispatchers who are responsible for relaying the information to the first responders. The 9-1-1 team works in partnership with Denver Police, Denver Fire and Denver Health Paramedics to ensure the safety and quality of life for residents, businesses and visitors in the City and County of Denver.

What to Expect When you Call 9-1-1 

Important Notes

  • Staying on the line does not delay emergency response. Emergency responders are dispatched simultaneously while you speak with the Emergency Call Taker. 
  • Do not hang up. If you are placed on hold, hang up, and redial- you will be sent to the back of the queue causing further delay. 

Call Process

  2. Know your location and be prepared to provide it 
  3. State your emergency and the number of people involved to the best of your ability 
  4. Follow the Emergency Call Taker's instructions. Simultaneously, dispatchers are sending the appropriate emergency response to your location.  
  5. Stay on the line until emergency responders arrive or until instructed to hang up. 


Text 9-1-1

How to Use Text to 9-1-1

  1. Enter the numbers "911" into the "To" field as you would any text message (do not include dashes). 
  2. In the message field, state the location of your emergency and a brief summary of the situation. The most important information is your location, be specific and give a street address if possible. (EXAMPLE: I'm at 1234 Main St, APT 10. Intruder is in my apartment.)
  3. The Emergency Call Taker will respond via text with a series of questions. Answer all questions and follow the instructions given to the best of your ability.
  4. Help is on the way, continue to respond to texts until the Call Taker ends the conversation. 

Important Considerations

  • Do not use abbreviations or slang, as the meaning could be misconstrued or create a delay in the arrival of emergency services. 
  • Be as attentive as possible to the text conversation with short and timely responses. 
  • Do not delete the messages or turn off your phone until the call taker concluded the conversation.

When to Use Text 9-1-1

Text to 9-1-1 supports individuals who are deaf, hard of hearing, or have a speech disability. It can also be used when people are: 

  • Unable to speak as a result of an injury or medical emergency 
  • Facing a threatening situation where a voice call could increase the threat or compromise safety 
  • In an area where a text message is the only option to request emergency services due to limited coverage 
  • In an area where phone lines and cell towers are overwhelmed and only a text can get through to request emergency services. 

What Else You Should Know

  • If you attempt to send a text to 9-1-1 in an area outside of Denver where the service is unavailable, you will be sent a "bounce-back" message advising you to contact emergency services by alternative means (Call 9-1-1). In this circumstance, Text to 9-1-1 is not available. 
  • Photos and videos cannot be sent to Denver 9-1-1 at this time. 
  • Text to 9-1-1 does not work with applications that do not support texting to and from U.S. phone numbers. 

Non-Emergency Services

Non-Emergency Line

 Non-Emergency Line: (720) 913-2000

Starting late June, Denver 9-1-1 will use a smart integrated voice response (IVR) system for non-emergency calls. This means that callers will reach an automated system designed to assist callers and direct them to the best resources for their needs rather than directly connecting callers to a call taker.

Over 90 percent of calls made to 9-1-1 come from mobile phones. While mobile phones can be an important public safety tool, they can also create unique challenges for emergency responders. 

When you dial 9-1-1 from a mobile phone, the 9-1-1 call taker has very little information to help you - only your phone number and a very general sense of your location. Denver's solution is Smart911.

Smart911 is a private, secure service that allows you to create a safety profile that provides 9-1-1 and emergency responders with important information you want them to know about yourself, your family members and pets, your home and your vehicles in any kind of emergency. The information you provide automatically displays on the 9-1-1 call taker's screen when an emergency call is placed from a phone number connected to your profile. These details can save seconds or even minutes during an emergency.

Services for People with Disabilities

9-1-1 services for Deaf, Hard of Hearing and Residents with Speech Disabilities

Denver 9-1-1 offers deaf, hard of hearing, and/ or individuals with speech disabilities Text 9-1-1 to access emergency response services within the City and County of Denver.  

Teletypewriters (TTY)

TTY is an electronic device for text communication with individuals who are deaf. The device uses a series of tones that allow users to communicate via a keyboard and telephone interface at 9-1-1. Deaf and hard of hearing community members are encouraged to maintain a TTY machine to access 9-1-1 when a text pager or email is unavailable.

Denver's 9-1-1 call takers are trained on the use of the TTY and check all 9-1-1 hang-ups and “silent” phone calls or “open lines” using both voice and TTY commands to verify if a member of the deaf or hard of hearing community is on the line.
