Denver 911

Denver 911 operators are trained to ask questions that will help you get the assistance you need as quickly as possible. It is important to stay on the line with your 911 operator until you receive instructions to hang up. If you are in danger, you may be instructed to leave the building, secure yourself in a room, or take other protective actions.

All 911 calls placed within the City and County of Denver's geographical boundaries are received and then screened to determine if the caller has a police, fire, or medical emergency. Police and medical calls for service are processed immediately by the 911 call-taker; all fire related calls are transferred to Denver Fire Dispatch.

Smart 911

Be smart about your safety

Over 90 percent of calls made to 911 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 911 from a mobile phone, the 911 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 911 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 911 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.

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 911. Deaf and hard of hearing community members are encouraged to maintain a TTY machine to access 911 when a text pager or email is unavailable.

Denver's 911 call takers are trained on the use of the TTY and check all 911 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.
