A Purple Alert is a state-issued public notification used to help find a missing adult with a cognitive, intellectual, or developmental disability who doesn’t fit the criteria for an AMBER or Silver Alert. It fills the gap between those two systems: AMBER Alerts cover abducted children, Silver Alerts focus on older adults with Alzheimer’s or dementia, and the Purple Alert is designed for adults in the middle, including people with autism, Down syndrome, or a traumatic brain injury.
Who a Purple Alert Covers
Eligibility varies by state, but the laws share a common frame. The missing person must usually be 18 or older and have a qualifying condition. That typically includes:
- An intellectual or developmental disability such as autism spectrum disorder or Down syndrome
- A traumatic or acquired brain injury that impairs cognitive function
- Other cognitive or emotional disabilities not caused by substance abuse
Substance abuse is the key exclusion in most statutes. If the impairment stems from drugs or alcohol, the person generally doesn’t qualify. Alzheimer’s and dementia-related disorders are also excluded, because those cases are routed through the Silver Alert system instead. Some states add an upper age limit. Texas, for example, defines an eligible adult as someone between 18 and 64 and uses Silver Alerts for anyone older.
Disability alone isn’t enough. Law enforcement must also determine that the disappearance presents a credible threat of immediate danger or serious bodily harm, and that the person is unlikely to return safely without intervention. A usable physical description has to be available, and the person’s information must be entered into a state or national crime information database before the alert goes out.
How a Purple Alert Gets Issued
Families and caregivers can’t activate a Purple Alert directly. The request runs through law enforcement, and each step filters out cases that don’t belong in the system.
It starts when someone reports the person missing to local police. Officers conduct a preliminary investigation to confirm the disappearance, verify the qualifying disability, assess the level of danger, and rule out a Silver Alert as the more appropriate tool. Once the criteria check out and the missing person’s details are in the crime database, the agency requests activation from the state body that manages the alert.
Some states scale the alert geographically. Florida distinguishes between a local Purple Alert, which targets the immediate area where the person is most likely to be, and a statewide alert, which goes out when the person may have traveled farther. That tiering keeps the notifications relevant to the people most likely to spot the person.
How the Alert Reaches You
Once activated, a Purple Alert pushes out through several channels at once so it reaches as many people as possible.
Wireless Emergency Alerts are usually the fastest. These are the loud, buzzing notifications that appear on cell phones. They aren’t a subscription service: if your phone supports WEAs, you receive them automatically based on your location, even when you’re traveling.1FEMA. Wireless Emergency Alerts
The Emergency Alert System delivers the information through television and radio.2Federal Communications Commission. The Emergency Alert System Alerts also go out through news coverage, social media, and digital highway message signs. The point is redundancy. Someone who misses the phone notification may still see the highway sign or hear a news bulletin.
What to Do if You Get a Purple Alert
Read the alert instead of swiping it away. It includes a physical description, what the person was last wearing, a likely direction of travel, and sometimes a vehicle description. A few seconds of attention is enough to register the details, which matters most if you’re in the area named.
If you spot someone who matches, call 911 right away. Tell the dispatcher your exact location, the direction the person was heading, and anything else you noticed. Speed matters: people with cognitive disabilities can cover surprising distances and may not respond to their own name or recognize danger around them.
Don’t approach the person or try to stop them yourself. Someone with a cognitive disability may become frightened or disoriented when confronted by a stranger and could run or walk into traffic. Be the eyes, not the responder. Keep unverified sightings off social media too, because false leads pull searchers in the wrong direction.
What Caregivers Should Do Before Anything Happens
If you care for someone who may wander, prepare now. Stress makes it hard to assemble details once the person is missing, and the information searchers need is much easier to gather on an ordinary day.
Keep current photos ready. A practical habit is to take a quick picture each morning showing what the person is wearing that day. Searchers need today’s clothing, not a portrait from last year. Save the photos somewhere easy to pull up on your phone.
Learn the person’s patterns. People with cognitive disabilities often follow their own internal logic when they wander. They may head toward a childhood home, a former workplace, or a place tied to a strong memory. Some are drawn to water or to mechanical sounds. Sharing those patterns with police can shrink the search area significantly.
Technology helps when it’s chosen for the right purpose. GPS tracking devices made for this situation, like Project Lifesaver transmitters worn on the wrist or ankle, give law enforcement a direct way to locate someone. GPS-enabled smartwatches can work too, though they rely on cellular coverage. Basic Bluetooth trackers such as AirTags have limited range and don’t give real-time location, so they’re not reliable for wandering. Door and window alarms or motion sensors can warn you the moment someone leaves the house.
When a person does go missing, call 911 before you start searching on your own. Every minute of delay cuts the odds of a quick recovery. Ask responders to search the home first and thoroughly, including closets, under beds, and any confined space, because people with cognitive disabilities sometimes hide rather than wander. Give searchers the person’s current medications, medical conditions, usual destinations, and any nearby water sources, since bodies of water are a particular danger. After the person is found, a medical evaluation is standard: they may have fallen, been exposed to heat or cold, or missed critical medication.
Which States Have a Purple Alert
Purple Alerts are created state by state. There is no national Purple Alert, so availability depends on where you live. As of 2025, states that have enacted Purple Alert legislation include Florida, Texas, Connecticut, Mississippi, Maryland, and Kansas, with other states considering similar bills.
Florida was one of the first states to formalize the system and is the model other legislatures look to. Texas enacted a related law known as Cain’s Law in 2019, establishing a statewide alert for missing adults 18 to 64 who face imminent danger. Connecticut expanded its missing person clearinghouse statute to specifically cover individuals with intellectual and developmental disabilities. Criteria and procedures differ from state to state, so look up your state’s law and the activation process before you ever need it.
If your state doesn’t have a Purple Alert, law enforcement still has tools for missing persons cases, and some states use broader endangered-missing-person protocols that serve a similar function without the Purple Alert label. In those states, calling local police immediately and giving them full details remains the fastest route to help.
