SFMTA on Twitter

The SFMTA’s Twitter account, @sfmta_muni, provides real-time alerts about Muni service disruptions, information about the SFMTA’s work and notices about upcoming events that affect transportation in San Francisco.

Staffed Hours

  • Monday - Friday: 5 a.m. - 9 p.m.
  • Saturday - Sunday: 9 a.m. - 6 p.m.*

*Weekend hours may vary to provide staff during special events.

Tweet or Not?

During staffed hours, we provide live Muni alerts and can respond to information requests from Twitter users who mention our handle, @sfmta_muni in their tweet. In providing live Muni service information, we can better assist customers who provide their location, Muni bus route or rail line, direction and their vehicle’s four-digit number. We may be able to provide other general transportation information if it’s readily available.

We also look to Twitter users as additional eyes and ears on the streets. We monitor Twitter for feedback and reports that may help inform our real-time transportation management.

Please submit non-emergency complaints and other customer service requests to 311 for investigation and follow-up. For emergencies, call 911.

Outside staffed hours, please contact 311 for 24/7 assistance all days of the year.
