An Endangered Missing Advisory is a public alert that law enforcement issues to help find a missing person who is in immediate danger but doesn’t fit the narrow criteria for an AMBER Alert. It covers older adults with dementia who wander, people with physical or intellectual disabilities, and anyone whose disappearance points to a serious risk of injury or death. The alert pushes a description and photo out through media, highway signs, and other public channels so ordinary people can help locate the person quickly.
The design difference matters. An AMBER Alert requires a reasonable belief that a child 17 or younger has been abducted and faces imminent danger.1Office of Justice Programs. Guidelines for Issuing AMBER Alerts An Endangered Missing Advisory has no such requirement. There doesn’t need to be a suspect, an abduction, or any evidence of a crime at all. The focus is entirely on the missing person’s vulnerability and the circumstances of the disappearance.2Office for Victims of Crime. Guide for Implementing or Enhancing an Endangered Missing Advisory
When Law Enforcement Can Issue One
Each state sets its own rules, but most plans follow federal guidance built around three criteria. All three have to be met:3Office of Justice Programs. Guide for Implementing or Enhancing an Endangered Missing Advisory
- The disappearance is unexplained or suspicious. A planned trip doesn’t qualify. Walking out of a care facility in the middle of the night without a coat does.
- The person is believed to be in danger. Age, health, a mental or physical condition, the weather, or the people they may be with have to create a real risk of serious injury or death.
- There is enough identifying information to help the public — a usable description, a photo, or vehicle details. Without that, an advisory can’t do its job.
No crime needs to have occurred. That’s what separates an EMA from an AMBER Alert, and it’s why the system exists: a 78-year-old man with Alzheimer’s who walked away from an assisted living facility in January is clearly endangered, but he doesn’t fit the AMBER framework at all.
How to Request an Advisory
You can’t trigger an advisory yourself. Only the law enforcement agency investigating the case, or an agency designated to issue advisories in that area, can authorize activation.3Office of Justice Programs. Guide for Implementing or Enhancing an Endangered Missing Advisory Report the person missing to local police, and they decide whether the circumstances meet the criteria.
Come to that report ready with specifics. The more complete the information, the faster an advisory can move:
- Name, age, height, weight, and distinguishing features like scars, tattoos, or birthmarks.
- A current, clear photograph. Without it, an advisory loses most of its effectiveness.
- What the person was wearing when last seen.
- If a vehicle may be involved, the make, model, color, year, and license plate number.
- Any medical conditions that establish why the person is in danger — dementia, insulin-dependent diabetes, a seizure disorder — and whether they are without medication they rely on.
- Where and when the person was last seen, their usual routes or destinations, and any suspected direction of travel.
This information also feeds the missing person record in the National Crime Information Center (NCIC). Federal law requires immediate NCIC entry for anyone under 21, with no waiting period. Agencies should enter adults over 21 promptly too, and many state EMA plans require the NCIC entry before the advisory process can move forward.3Office of Justice Programs. Guide for Implementing or Enhancing an Endangered Missing Advisory
Where the Alert Actually Shows Up
Once activated, the advisory travels through whatever channels the state has set up. The mix varies, but the ones a member of the public is most likely to encounter include:3Office of Justice Programs. Guide for Implementing or Enhancing an Endangered Missing Advisory
- Television and radio broadcasts through local and regional stations.
- Electronic highway signs displaying the description or vehicle information to motorists.
- Lottery terminals in several states, which print missing person information on terminal displays and customer receipts.
- Social media posts and agency websites for rapid sharing.
- Automated phone calls, including reverse-911, targeted to residents in a specific area.
Many state plans set the default duration at 24 hours. After that, the investigating agency can renew, update, or cancel the advisory.
The 2025 FCC Alert Code
A national piece fell into place in 2025. The FCC established a dedicated “MEP” (Missing Endangered Persons) event code for the Emergency Alert System, effective September 8, 2025. Tribal, state, and local law enforcement can now select MEP as an event code type when originating alerts through EAS.4Federal Communications Commission. Missing Endangered Persons Emergency Alert System Code Before this, no standardized EAS code existed for missing endangered adults, and agencies had to improvise with less targeted options.
Why Your Phone May Not Buzz
The Wireless Emergency Alert (WEA) system that pushes notifications to cell phones is a separate system with a narrower scope. Participating wireless carriers are only required to transmit four classes of alerts: Presidential Alerts, Imminent Threat Alerts, Child Abduction Emergency (AMBER) Alerts, and Public Safety Messages.5eCFR. 47 CFR Part 10 – Wireless Emergency Alerts An Endangered Missing Advisory for an adult does not have its own WEA category. Some missing-child cases can reach phones through the AMBER/Child Abduction class, which includes lost, injured, or otherwise missing children and endangered runaways. A missing 70-year-old with dementia won’t trigger the same phone alert. That is a large part of why the EAS television and radio code matters.
How This Compares to AMBER, Silver, and Ashanti Alerts
The alert systems overlap enough that people mix them up. An AMBER Alert is the most restrictive. It requires a reasonable belief that an abduction has occurred, that the victim is 17 or younger, that the child faces imminent danger of serious injury or death, and that the child’s information has been entered into NCIC before the alert goes out.1Office of Justice Programs. Guidelines for Issuing AMBER Alerts Miss any of those, and an AMBER Alert isn’t available no matter how urgent the situation feels.
Silver Alerts overlap with Endangered Missing Advisories but aren’t identical. Roughly 42 states and the District of Columbia have Silver Alert laws, and most target older adults or people with cognitive impairments. Minimum qualifying ages run from 18 to 65 depending on the jurisdiction. Some states run Silver Alerts and EMAs as separate programs with different activation rules; others use the terms interchangeably.
The Ashanti Alert Act created a national communications network for missing adults who are too old for AMBER Alerts. Under the statute, a “missing adult” is someone older than the AMBER age threshold in their state, identified as missing by law enforcement, and meeting that state’s requirements for designation as a missing adult.6Office of the Law Revision Counsel. 34 USC 21901 – Definitions Ashanti provides federal coordination, but activation still depends on state and local plans.
When the Person May Have Crossed State Lines
There is no automatic reciprocity that extends an advisory into a neighboring state. The investigating agency has to contact the relevant agencies along the suspected route and ask them to activate their own alerts. Each state controls its own activation based on its own criteria.
The NCIC entry helps here because it’s a national database any law enforcement agency can access. If a patrol officer in a neighboring state runs a license plate or encounters someone matching the description, the NCIC flag identifies the person as the subject of an active missing person case. Federal coordination through the Ashanti Alert network is designed to speed up this cross-state communication for missing adults, though how well it works still depends on the state plans in place.6Office of the Law Revision Counsel. 34 USC 21901 – Definitions
If You See Someone From an Active Advisory
Call the phone number listed in the alert right away. Don’t approach the person yourself, especially if the advisory mentions a potentially dangerous companion. Give the dispatcher your exact location, the direction the person was heading, and anything you noticed that wasn’t in the original description.
Law enforcement cross-references tips against the case file and dispatches officers to the area. Most agencies prioritize these leads heavily in the first 24 hours, when the chance of a safe recovery is highest. Once the person is found, the investigating agency cancels the advisory and pulls it from active channels.
