San Mateo County, CA sheriff non-emergency number

When to call 911 instead

Call 911 if any of this is true right now:

• Someone is injured, unconscious, or threatening to hurt somebody.
• A crime is in progress, or the suspect is still nearby.
• There is a fire, a gas smell, or a crash with injuries or blocked traffic.
• You are not sure. A dispatcher would rather triage one unnecessary 911 call than miss a real one.

Use the non-emergency number for things that have already finished and nobody is in danger:

• A theft, burglary, or vandalism discovered after the fact, including when you need a report number for insurance.
• A car blocking a driveway or hydrant, an abandoned vehicle, a parking complaint.
• Noise, a loud party, fireworks, or a barking dog.
• A minor collision with no injuries where the vehicles have been moved.
• Found property, a follow-up on an existing case, or a general question for San Mateo County Sheriffs Office.

Non-emergency lines are usually answered by the same communications centre as 911, but at a lower priority — expect to hold, and expect to be asked whether anyone is in danger.

Sheriff's office details

311 and 211

311 is for city services rather than policing — potholes, missed collections, street lights, parking, and in some cities non-emergency police reports. Where a city runs a 311 service, the page says so above.

211 is a free nationwide line for health and human services: housing, food, utility assistance, mental health, and crisis support. It is operated by local United Way and partner organisations and is available in most of the country by dialling 211 or through 211.org.
