How to Sign Up for Los Angeles County Emergency Alerts - and What the System Actually Does
How do I sign up for emergency alerts in Los Angeles County?
Los Angeles County residents can register for NotifyLA, the county's opt-in emergency alert system, through the Los Angeles County Office of Emergency Management at lacounty.gov. Registration is free and lets you choose to receive alerts by phone call, text, or email based on your registered address. Cell phones and email addresses are not automatically enrolled and require manual sign-up.
Is Wireless Emergency Alert registration required in Los Angeles County?
No registration is required for Wireless Emergency Alerts, the federal system that automatically sends alerts to cell phones located in an affected geographic area. However, WEA only covers broad emergencies and doesn't reach landlines or email. To receive neighborhood-level evacuation orders and localized alerts, Los Angeles County residents should separately enroll in NotifyLA at lacounty.gov.
What is the difference between an evacuation warning and an evacuation order in LA County?
In Los Angeles County, an evacuation warning means residents should prepare to leave and that those with medical needs, mobility limitations, or animals should go immediately. An evacuation order is a legal directive to leave the area at once. Both are issued through NotifyLA and Wireless Emergency Alerts, and the specific category is stated in the alert message itself.
Will LA County automatically have my cell phone number for emergency alerts?
No. Los Angeles County's NotifyLA system may have landline numbers on file through public records, but cell phone numbers and email addresses are not automatically included. Residents must manually register their cell number and preferred contact methods at the NotifyLA portal through lacounty.gov to ensure they receive neighborhood-level emergency alerts on a mobile device.
Does NotifyLA work for people who live in cities like Pasadena or Burbank inside LA County?
Yes, NotifyLA covers all of Los Angeles County, including incorporated cities like Pasadena and Burbank. However, those cities may also operate their own city-level alert systems and can issue evacuation orders through their own emergency management offices. Residents in incorporated cities are generally encouraged to enroll in both NotifyLA and any city-specific alert system their municipality offers.

Wildfires, earthquakes, flooding, hazardous materials incidents - Los Angeles County runs one of the largest and most complex emergency alert systems in the United States, covering more than 10 million residents across 88 cities and unincorporated areas. But the system only works if you're registered, and a significant number of county residents aren't. Here's how to get signed up and what to expect when an alert goes out.

The Two Systems LA County Uses
Los Angeles County operates two overlapping alert systems. The first is Wireless Emergency Alerts (WEA), the federal system that automatically pushes alerts to cell phones in a geographic area - no sign-up required. If you have a cell phone with WEA enabled and you're physically inside the affected area, you'll get the alert as a loud, buzzing text-style message. WEA is handled at the federal level and covers broad threats like active wildfires and tsunami warnings.
The second system is NotifyLA, which is the county's own opt-in platform. NotifyLA is run by the Los Angeles County Office of Emergency Management and can reach you by phone call, text message, or email at an address the county has on file for you. This is the system that fills in the gaps - neighborhood-level evacuation orders, local road closures, utility emergencies, and other incidents that are too localized for a county-wide wireless blast. It's also how the county reaches landlines, which WEA doesn't cover.
How to Register for NotifyLA
Registration is through the NotifyLA portal, which is managed by the Los Angeles County Office of Emergency Management. You can reach it at lacounty.gov or search "NotifyLA registration" directly. The sign-up process asks for your address, which is how the system determines which alerts are relevant to your specific location, and then asks how you want to be reached - phone, text, or email - and at what numbers or addresses.
If you own a home or are a long-term renter with a landline registered to your address, the county may already have your number in the system through public records, but that's not a guarantee. The county's Office of Emergency Management recommends confirming your registration regardless. Cell phone numbers and email addresses are not automatically enrolled - those require manual sign-up.
There's no fee to register. The process takes a few minutes. You can add multiple contact methods and multiple addresses, which is useful for people who want alerts for a second property, an aging parent's address, or a child's school area.
What Happens When an Alert Goes Out
During an active emergency, NotifyLA sends alerts in tiers based on your address's proximity to the incident. The county uses four main categories that residents should know: Evacuation Warning (leave if you need extra time or have special needs), Evacuation Order (leave now, this is a legal directive), Shelter in Place (stay indoors, close windows), and an informational notice for lower-level advisories. These categories appear in the alert text itself.
The Los Angeles County Sheriff's Department and the county's Operational Area Emergency Operations Center coordinate the actual issuance of evacuation orders. For fires in incorporated cities like Pasadena or Burbank, the city's own emergency management office may issue orders under their own authority and may use their own alert channels in addition to NotifyLA - which is why residents in incorporated areas are sometimes encouraged to sign up for city-level alerts as well. Unincorporated areas rely entirely on county systems.

WEA alerts, when activated, come with a specific tone and vibration pattern distinguishable from regular texts. You can check your phone's settings under "Emergency Alerts" or "Safety and Emergency" (the label varies by device and carrier) to confirm WEA is enabled on your phone. Some users have inadvertently turned it off.
Additional Resources and Special Needs Registration
Los Angeles County also maintains a program for residents with access and functional needs who may require additional assistance during an evacuation. The program is coordinated through the county's Office of Emergency Management and connects residents with mobility limitations, medical equipment dependencies, or other barriers to self-evacuation with local emergency services. Registration for this program is separate from NotifyLA enrollment - contact the Office of Emergency Management or your local city emergency management office for current details on how to apply, as the process and eligibility criteria can vary.
The county's Office of Emergency Management publishes preparedness guides in multiple languages at lacounty.gov/emergency, and the Los Angeles County Fire Department maintains its own public information page with fire-specific resources, including real-time incident maps during active fires. The county also encourages residents to bookmark ready.lacounty.gov, which aggregates preparedness checklists and current emergency information in one place.
This is general information, not legal or financial advice - check the Los Angeles County Office of Emergency Management at lacounty.gov/emergency and the NotifyLA registration portal for guidance on your specific situation and the most current enrollment process.
