A Silver Alert is a state-run public notification that broadcasts the description of a missing vulnerable adult, most often a senior with Alzheimer’s disease or dementia, so the public can help find them. Most states run their own program, and when one is activated, the person’s details go out across television, radio, highway message signs, and social media. The rules for who qualifies and how the alert travels depend entirely on the state.
Who Qualifies
Eligibility varies by state, but most programs share the same core criteria. The missing person is usually 60 or 65 and older, though many states also cover younger adults with a documented cognitive impairment such as Alzheimer’s, dementia, or a developmental disability. Before issuing an alert, law enforcement typically needs to confirm three things:
- The disappearance poses a credible threat to the person’s health or safety.
- Officers have enough description of the person, and of any vehicle involved, to make a public alert useful.
- Someone has filed a missing person report with a law enforcement agency.
Some states extend eligibility to any adult whose disappearance suggests endangerment, regardless of cognitive status. Others hold to strict age cutoffs. There is no federal Silver Alert law, so the standards are whatever your state has written.
How an Alert Gets Issued
It starts with a phone call to local police or the sheriff’s office. There is no required 24-hour or 48-hour waiting period before you can report an adult missing. That belief is a persistent myth, and acting on it costs time that could save a life when someone with dementia has wandered.
Once the report is filed, officers evaluate whether the facts meet the state’s Silver Alert criteria. If they do, the agency coordinates with state-level partners to push the alert out. Speed is the decisive factor. Research on dementia-related wandering shows outcomes worsen the longer someone is missing, especially in extreme weather or near highways and water.1National Library of Medicine.

How Alerts Reach the Public
An active Silver Alert spreads through several channels at once. Commercial TV and radio stations broadcast the person’s description. Highway variable-message signs display vehicle details and plates in participating states. Law enforcement and state emergency management agencies post to social media. If the person is believed to be on foot, some jurisdictions use reverse-911 or local emergency notification systems to reach nearby residents.
One point of confusion is worth clearing up. Silver Alerts do not go out through the federal Wireless Emergency Alerts system, the technology behind the loud buzzing notifications on your phone. WEA is limited to four categories: presidential alerts, imminent threat warnings, AMBER Alerts for missing children, and public safety messages.2Federal Communications Commission. Wireless Emergency Alerts (WEA) A Silver Alert reaches a cell phone only through an opt-in state notification app, social media, or a local emergency call system. That gap in distribution is the single biggest limit on the program’s reach.
What to Do If You See a Silver Alert
A Silver Alert will give you the person’s name, age, physical description, what they were last wearing, where they were last seen, and a description of any vehicle along with the license plate.
If you spot someone who matches, call 911 or the number listed in the alert. Give the dispatcher your exact location and describe what you’re seeing. Don’t approach the person yourself. Someone with advanced dementia may not understand that you’re trying to help, and the contact can trigger panic or cause them to run. Let trained responders make the approach.
Alerts stay active until the person is found or the agency formally cancels them. When a missing person is located, the issuing agency pulls the alert back through the same channels that carried it.
What to Do If Your Family Member Goes Missing
Call local police or the sheriff’s office immediately. You don’t need to request a Silver Alert by name. File a missing person report and give officers everything you can:
- The most recent photograph you have.
- Height, weight, hair color, and what the person was last wearing.
- Any diagnosed cognitive condition, with documentation if you can produce it.
- Where they were last seen and when.
- Make, model, color, and plate of any vehicle they have access to.
- Places they return to out of habit: former workplaces, childhood neighborhoods, familiar stores.
Law enforcement decides whether the facts meet Silver Alert criteria. If your state has no Silver Alert program, police still work the case through their standard missing-person process. The alert system is a broadcast tool on top of that investigation, not a prerequisite for a search.
How Silver Alerts Compare to AMBER and Ashanti Alerts
The country runs several missing-person alert systems, each covering a different population.
AMBER Alerts cover abducted children under 18. They have federal backing and are distributed through the Wireless Emergency Alerts system, which pushes notifications to every nearby cell phone without any opt-in.2Federal Communications Commission. Wireless Emergency Alerts (WEA) That reach is unmatched by any other missing-person alert.
Silver Alerts cover vulnerable adults with cognitive impairments. The programs are state-operated, with no federal mandate and no WEA access, so effectiveness depends on the media partnerships, highway sign networks, and notification systems each state has built.
Ashanti Alerts fill the gap between the other two. Created by the Ashanti Alert Act of 2018, this system set up a voluntary national communication network through the Department of Justice to help find missing adults over 17 who don’t fit AMBER or Silver criteria.3Bureau of Justice Assistance. Ashanti Alert Act National Notification System The law covers people with documented mental or physical disabilities, along with anyone missing under circumstances suggesting their safety is at risk or their disappearance was involuntary.4GovInfo. Ashanti Alert Act of 2018 As with Silver Alerts, states, territories, and tribal authorities run their own reporting and alert processes.
Reducing the Risk Before Someone Goes Missing
If you care for someone with dementia, the most useful thing you can do is prepare for wandering before it happens. A Silver Alert is a recovery tool. Prevention is better.
GPS tracking devices built into watches, pendants, or shoe inserts transmit a person’s location to your phone in real time. Standard GPS works best outdoors, since buildings and heavy tree cover can block satellite signals. Network-assisted GPS, which combines cell towers with satellites, tracks more reliably indoors and in dense urban areas. Some services let you set a geofence that triggers an automatic alert when the person leaves a defined area.
Medical identification jewelry or clothing labels listing the person’s name, condition, and an emergency contact number help strangers and first responders identify someone who can’t speak for themselves. Door and window alarms, childproof locks installed unusually high or low, and motion sensors near exits can buy you time before someone slips out.
Check whether your local law enforcement agency has a vulnerable adult registry. Those programs let you pre-load a photograph and descriptive details so officers already have the information on file if the day comes. Tell your neighbors too. A short conversation letting the people next door know that your family member has dementia and might wander turns them into an informal early warning system that can react faster than any official broadcast.
