Denver's Digital Pulse: How SMS Messaging Shapes the Mile High City

Denver's communication landscape has undergone a remarkable transformation since the first SMS message, a simple "Merry Christmas," was sent on December 3, 1992.

 

Today, the city leverages advanced messaging systems to keep its residents informed and connected.

 

In April 2022, Denver expanded its use of the Everbridge platform to enhance citizen safety amid increased wildfire risks.

 

This system allows officials to deliver timely alerts via SMS, landline, and mobile app, ensuring that over 700,000 residents receive critical information during emergencies.

 

Neighborhoods like RiNo, Cherry Creek, Five Points, and The Highlands utilize messaging platforms to organize events, share updates, and foster community engagement.

 

In a city where residents are constantly active and mobile, texting has become the preferred method of communication.

 

However, the reliance on digital communication is not without challenges.

 

In March 2025, it was revealed that the encrypted messaging app Signal was not approved for use on city-issued devices, raising concerns about transparency and compliance with open records laws.

 

Additionally, in December 2025, a cyberattack disrupted the CodeRED alert system in at least two Colorado counties, highlighting the vulnerabilities in digital communication infrastructure.

 

Despite these challenges, Denver continues to innovate and adapt its communication strategies.

 

The city's journey from the first SMS to today's sophisticated alert systems mirrors its broader evolution—a testament to its resilience and commitment to keeping its community connected and informed.
