How the Silver Alert Process Works in California
How California's Silver Alert process works: the five legal criteria, who can request an alert, what to do during one, and tools that reduce wandering risk.
The first thing to know about the silver alert process for missing elderly in California is also the thing families often learn at the worst possible moment: a Silver Alert is not a general missing-person service, and relatives cannot activate it themselves. You call 911 and make a missing-person report. Local law enforcement decides whether the legal criteria are met. If they are, that agency requests activation through the California Highway Patrol, which runs the statewide alert system through its Emergency Notification and Tactical Alert Center, or ENTAC, in Sacramento.[1][2]
That distinction matters when a parent with dementia is gone, the sun is dropping, and everyone in the house is arguing over whether to wait another hour. The Silver Alert can be a powerful amplifier, but it is a backstop. The work that helps police move quickly starts before the alert: a current photo, a real description, vehicle details if the person may be driving, medical risk information, and one person ready to answer calls.

The California Silver Alert chain, in plain English
In California, the path runs from the family to local law enforcement, then to CHP. The public usually sees the last part — the highway sign, phone alert, TV or radio notice, or @CHPAlerts post — but the legal decision has already happened before that broadcast appears.[1][2]

- Call 911. Say the person is missing, give the last known location and time, and explain the dementia, cognitive impairment, age, medical condition, weather risk, or other danger.
- Local law enforcement takes the missing-person report and evaluates whether the Silver Alert criteria are met. Families can ask whether a Silver Alert is being considered, but they do not make the request directly to CHP.
- The local agency uses local resources first. Under the statute, those resources must be exhausted before a Silver Alert is requested.[1][3]
- If all criteria are met, local law enforcement requests activation through CHP’s ENTAC, which operates 24 hours a day in Sacramento.[2]
- CHP disseminates the alert through current channels that can include the Emergency Alert System for TV and radio, highway variable-message signs, @CHPAlerts on X, and Wireless Emergency Alerts to smartphones.[1][2]
The original enrolled bill for California’s Silver Alert law included a January 1, 2016 sunset date, but CHP’s current materials describe the program as active, and California Silver Alerts remain in use in 2026.[1][3] Older descriptions of the system may not match current dissemination channels; current CHP guidance is the source to follow.
The five criteria that decide whether a Silver Alert can be issued
Most family frustration comes from this point: the person can be missing and vulnerable, and still not automatically qualify for a Silver Alert. California Government Code §8594.10 sets five criteria. CHP’s public criteria page lists the same five-part test.[1][3]
| Legal criterion | What it means at the kitchen table |
|---|---|
| The missing person is 65 years of age or older, developmentally disabled, or cognitively impaired. | A person does not have to be 65 if they are cognitively or developmentally impaired. A 65-plus age threshold is one path; documented cognitive impairment is another. |
| The investigating law-enforcement agency has utilized all available local resources. | Police generally need to work the local missing-person response first. A Silver Alert is not the family's first call; it is requested after local resources have been used. |
| The law-enforcement agency determines that the person has gone missing under unexplained or suspicious circumstances. | This is more than being late or not answering the phone. Officers are looking at whether the disappearance cannot be explained in a routine way or raises concern. |
| The person is believed to be in danger because of age, health, mental or physical disability, environment, weather, or other circumstances. | This is where dementia, medication dependence, heat, cold, mobility problems, nighttime wandering, or unsafe driving risk may matter. |
| There is information available that, if disseminated to the public, could assist in the safe recovery of the missing person. | Police need something useful to share: a photo, clothing, vehicle, plate, direction of travel, likely destination, or other identifying detail. |
The last criterion is the one families can influence the most before anything happens. If the only available photo is ten years old, nobody knows the shoes, and the license plate is “maybe starts with a 6,” law enforcement has less to broadcast. A one-page emergency folder is not busywork; it is the public description that may get pushed across California.
Why “local resources exhausted” does not mean “do not call yet”
Families sometimes hear “local resources must be exhausted” and interpret it as a reason to search alone first. That is backward. The law-enforcement agency is the one that uses and evaluates those resources. Your job is to report the disappearance quickly, give useful facts, and keep your phone available.
This is also why a caregiver should not spend the first hour calling every cousin before calling 911. If the person has dementia, is cognitively impaired, is medically vulnerable, may be driving, or may be exposed to heat, cold, traffic, water, or terrain, report it. Let law enforcement decide the alert path.
What to do in the first 24 hours
The first day is not just emotionally important. In a critical review of missing-person programs for wandering elders, Petonito and colleagues reported Koester’s 1998 survival data: all persons with dementia located within 24 hours survived, while survival dropped to about 54% when the person was found after 24 hours.[4] That does not mean every case follows the same pattern, but it does mean “wait and see” is a dangerous default.
- Call 911 as soon as you believe the person is missing and at risk. If dementia or cognitive impairment is involved, say that clearly.
- Give the dispatcher the person’s full name, age, height, weight, hair, eye color, current photo, clothing, medical conditions, medications, mobility limits, language needs, and whether they may resist help or appear confused.
- If a vehicle is involved, give the make, model, color, year if known, license plate, damage or stickers, and likely routes. Do not leave this for later because vehicle information can make an alert much more actionable.
- Check the immediate area without delaying the report. The Alzheimer’s Association says six in ten people living with dementia will wander at least once, advises calling 911 within 15 minutes if the person is not found, and says many individuals who wander are found within 1.5 miles of where they disappeared.[5]
- Assign one person to stay reachable. If police, a hospital, a neighbor, or a transit agency calls, someone needs to answer.
- Write down the timeline as it becomes clear: last seen, last phone contact, doorbell-camera sighting, bank-card use, vehicle sighting, neighbor report. Memory gets worse under stress.
If several relatives are present, give people jobs instead of letting everyone do the same frantic thing. One person talks to police. One gathers the photo and medical list. One checks nearby yards, garages, sheds, walking routes, transit stops, and familiar places. One keeps a written log. Nobody should be driving around with the only working phone and no charger.
Build the emergency folder before you need it
The folder can be paper, digital, or both. What matters is that the person calling 911 can find it in under a minute.
- Recent face photo and full-body photo
- Legal name, nicknames, date of birth, height, weight, hair and eye color
- Diagnosis or cognitive condition, if known
- Medication list and urgent medical risks
- Mobility aids, hearing aids, glasses, dentures, or communication needs
- Common destinations: former workplaces, old homes, church, favorite stores, bus stops, parks, clinics
- Vehicle make, model, color, plate, insurance card copy, and a photo of the car
- Primary caregiver contacts, backup contacts, neighbors with keys, and preferred hospital

If you receive or see a Silver Alert
For the public, the instruction is simple: if you see the missing person, the vehicle, or something matching the alert, call 911. Give the location, direction of travel, time seen, person description, vehicle description, and license plate if visible. CHP tells the public not to approach the person.[1]
That “do not approach” line is not cold. A missing elder may be frightened, confused, medically unstable, or standing near traffic. A good 911 call with a precise location is more useful than a well-meaning stranger trying to handle a situation alone.
What successful alerts can look like
CHP’s success stories include a 78-year-old man who was reported missing after leaving home in a vehicle. CHP describes the alert being issued, the vehicle being located, and the man being found alive after officers and allied agencies coordinated the response.[6] The useful part of that story is not that an alert magically solved everything; it is that a report, vehicle information, public dissemination, and police follow-up lined up.
A more recent Northern California case shows how far that chain can reach. In March 2026, an 83-year-old Shasta County man was found about 200 miles away in Solano County after a Silver Alert and automated license-plate reader information helped authorities locate him, according to the Redding Record Searchlight.[7] For families in rural counties, that matters: a missing driver may cross jurisdictions long before relatives finish searching the usual streets.
Still, recovery after an alert does not prove the alert alone caused the recovery. Petonito and colleagues cautioned that it is “impossible to tell” how many recoveries are directly attributable to the alert rather than other search activity; in Florida data they reviewed, only 51 of 377 recoveries were reported as alert-attributable.[4] That is the honest frame: the Silver Alert is a powerful layer in a larger search, not a guarantee.
The prevention layer belongs in the same plan
A good Silver Alert plan does not begin with the alert. It begins with reducing the odds that someone can leave unnoticed, unidentified, or impossible to locate.
The Alzheimer’s Association’s wandering guidance puts the scale plainly: six in ten people living with dementia will wander at least once.[5] MedlinePlus recommends practical home-safety measures such as identification bracelets, door alarms, signs on doors, and securing unsafe areas.[8] Those tools are not glamorous. They are the difference between hearing a door chime at 6:40 p.m. and discovering an empty bedroom at 7:25 p.m.
For a deeper look at prevention technology, compare options in dementia monitoring systems that work for wandering risk. GPS trackers, passive sensors, and phone-based location sharing raise consent and dignity questions, especially early in cognitive decline, but they also give families and first responders more than a guess.
Home changes matter too. A dementia-aware house can use visual cues, safer exits, lighting, reduced trip hazards, door alerts, and calmer layouts. If wandering risk is rising alongside falls, start with dementia-friendly home modifications by stage rather than waiting for the first police report.
Emergency planning should include wandering, especially during evacuations, power outages, storms, heat events, or family disruptions. A person who is usually safe at home may leave when routines break. The same emergency folder used for a Silver Alert belongs with the household’s senior storm preparedness checklist.
Free help for eligible Los Angeles County residents
Los Angeles County’s L.A. Found program offers eligible residents access to tracking technology, including Project Lifesaver radio-frequency bracelets and Theora GPS smartwatches. The county says more than 1,800 devices have been distributed and 29 reunions have occurred through the program; families can call (833) 569-7651 for information.[9]
Other counties may have their own local programs, registry options, or sheriff’s-office resources. Ask before there is an emergency. In the middle of a disappearance, nobody should be learning the phone tree from scratch.
The part families can control
You cannot force a Silver Alert. You can report quickly, give law enforcement the facts needed to evaluate the five criteria, keep vehicle and description information ready, search nearby without delaying 911, and make sure the person is easier to identify and locate before a crisis. In California, that is the practical order: know the criteria, know the chain, prepare the information, act fast, and build enough prevention that the alert remains the backup plan.
