311 Day (often called National 311 Day) is an annual observance on March 11 that promotes the use of the 311 non‑emergency phone line and related apps to connect residents with city services instead of calling 911 for non‑urgent issues.

What is 311 Day?

  • Observed every year on March 11 (3/11) in many parts of the United States.
  • Its main purpose is to remind people that 311 is the number to call for non‑emergency city services, so 911 can stay focused on real emergencies.
  • It highlights the workers who answer these calls and help route requests, sometimes called the “first” first responders for non‑crisis situations.

What 311 is used for

Typical things people report or ask about through 311 include:

  • Potholes, broken sidewalks, or damaged streets and parks
  • Graffiti, illegal dumping, or debris in the road
  • Streetlight outages and blocked sidewalks
  • Noise complaints or non‑emergency public safety concerns
  • Questions about local services (trash pickup, parking rules, city programs, accessibility issues)

How 311 Day started

  • The 311 system itself was first adopted in the 1990s as a way to take pressure off 911 by routing non‑emergency calls elsewhere.
  • National 311 Day as a named observance was launched around 2020 with support from cities like Las Vegas, Los Angeles, Oakland, San José, and Santa Clara County, in partnership with Google.
  • Since then, more cities and counties have promoted March 11 as a day to spread awareness of 311 and related mobile apps.

Why 311 Day matters

  • Using 311 instead of 911 for non‑urgent problems helps emergency responders reach life‑threatening cases faster.
  • It makes it easier for residents to get answers about local government services without needing to know specific department numbers.
  • It encourages people to see themselves as active “eyes and ears” for their community by reporting issues that need attention.

How people observe 311 Day

Common ways cities and residents mark the day include:

  1. Checking whether their city has 311 (phone line, website, or app) and learning when to use it.
  2. Submitting a non‑emergency service request (for example, a pothole or streetlight outage) through 311.
  3. Downloading a city’s 311 app, if available, and trying it out.
  4. Sharing information about 311 with friends, family, or neighbors so they know not to call 911 for routine issues.
  5. Posting on social media using hashtags like #National311Day or #311Day to spread awareness.

Other use of “311 Day” (music fans)

There is also a separate “311 Day” tradition among fans of the rock band 311, where the band holds special concerts around March 11, often in cities like Las Vegas.

So depending on the context, “311 Day” can mean either the civic awareness day about the 311 non‑emergency line or the band’s fan celebration event.
