What to Do When Someone Goes Missing: Reporting, Search Support, and Reliable Resources

Learning that someone cannot be located can be frightening and disorienting. Start with safety, clear facts, and the professionals responsible for the search. This guide uses U.S. resources; if you are outside the United States, contact your local emergency services and national missing-person authority. Exact reporting rules, alert criteria, and investigative procedures vary by jurisdiction.

1. Call local law enforcement first

If the person may be in immediate danger, call 911 (or your local emergency number). Otherwise, contact the law-enforcement agency with jurisdiction over the place they were last known to be. Do not wait to assemble every detail or to conduct a social-media search before making the report. Say plainly that the person is missing and describe any immediate safety concern: age, health or medication needs, possible exposure to danger, threats, vulnerable circumstances, or a reason to believe they cannot care for themselves.

Ask for the report or case number, the investigator’s name and contact information, and the preferred way to provide updates. Keep those details in one place. The U.S. Department of Justice directs families of missing children to call local law enforcement first. For a missing child, the National Center for Missing & Exploited Children (NCMEC) also advises asking that the child’s identifying information be entered in the FBI’s National Crime Information Center (NCIC) Missing Person File.

An agency’s intake process, records entry, alert decision, and search response depend on local law, facts, and available authority. An AMBER Alert, for example, is not a tool families activate themselves. Ask the investigating agency what steps are appropriate and how it will keep you informed.

2. Preserve the facts while they are fresh

Make a dated, factual record. It should separate what you know directly from what someone else reported. Useful details include:

• The last confirmed date, time, location, and circumstances; who saw or spoke with the person.

• A recent, clear photograph and a description of clothing, footwear, belongings, vehicle, and distinctive features.

• Full name, date of birth, physical description, phone number or online accounts, regular destinations, transportation, and people who may have relevant information.

• Health, communication, mobility, or safety information that could help responders locate or identify the person.

Save original messages, call logs, voicemail, photos, and relevant links; note their date and time rather than rewriting them from memory. Preserve anything that may matter to investigators and follow their instructions about rooms, vehicles, devices, or other possible evidence. Do not alter, delete, or publicly post private material just to make a faster appeal. Avoid guessing passwords, accessing accounts without authority, or independently confronting anyone. Provide the original material and context to law enforcement.

3. Create one reliable channel for updates

Choose one family point of contact, if possible, and keep a simple log: when information arrived, who supplied it, what was shared with investigators, and what follow-up was requested. Give every tip—however uncertain—directly to the investigating agency or the official number listed on a verified poster. A single, calm channel reduces duplicated reports, rumor-driven decisions, and the risk that important details get lost.

Ask before organizing a physical search. Investigators may know of hazards, legal limits, active search areas, or information that should not be shared. Do not enter private property, put yourself at risk, or turn an unverified sighting into a public accusation.

4. Use official resources that match the situation

Law enforcement remains the starting point. Additional resources can support a case, but they do not replace a police report.

For a missing child in the United States, call NCMEC at 1-800-THE-LOST (1-800-843-5678) after reporting to local law enforcement. NCMEC’s case-management team works with families and investigating agencies and may provide case-specific technical assistance, poster support, lead handling, peer support, and referrals. Use NCMEC’s official channels rather than a look-alike page or an unofficial fundraiser.

For missing people of any age, the U.S. Department of Justice’s National Missing and Unidentified Persons System (NamUs) is a national resource and searchable database involving missing, unidentified, and unclaimed-person cases. Public users can submit a missing-person case and search publicly visible records; NamUs notes that a missing-person case requires an active law-enforcement report. Its staff and services can support criminal-justice agencies with case consultation and forensic or analytical resources. Ask your investigator how NamUs fits your case and whether any records or documentation would be helpful.

The FBI supports certain federal child-abduction, kidnapping, and missing-person matters. It is not a substitute for reporting locally. Follow the investigator’s direction about federal involvement and use the FBI’s official missing-person pages only for verified information or tips.

5. Share responsibly—and only what helps

Public sharing can generate useful information, but it can also expose the missing person and their family. Before posting, ask the investigator whether a public appeal is appropriate and whether an official NCMEC or agency poster is available. Share the most recent approved photo, basic identifying information, last-known facts that law enforcement has cleared for release, and the correct official tip contact.

Keep the post focused. Do not publish a home address, private medical or school records, financial information, passwords, live location data, intimate images, or accusations. Do not identify witnesses or speculate about a cause of disappearance. Ask people to send possible tips to law enforcement, not to debate theories in comments or contact people who may be involved.

Treat online claims as unverified until investigators confirm them. Save a useful post, screen capture, or message with its link and time, then forward it through the agreed channel. Correct inaccurate posts promptly, and when the person is found, ask organizers and sharers to remove or update public appeals in coordination with law enforcement. Respecting privacy is part of protecting the person.

6. Be alert to scams and pressure tactics

A crisis can attract people seeking money, data, or attention. Be especially cautious of callers claiming to have a sighting, to represent law enforcement or a hospital, or to need payment for a search, a tip, legal help, or a "rescue." Preserve the message and tell the investigator, but do not send money, gift cards, cryptocurrency, passwords, one-time codes, or identifying documents in response to pressure.

The Federal Trade Commission advises people facing an urgent family-emergency request to slow down and verify independently: use a phone number you already know is correct, contact another trusted person, and resist secrecy or immediate-payment demands. A real tip may still need careful handling—do not attempt a payment, meet-up, or recovery on your own. Report suspected fraud to the FTC at ReportFraud.ftc.gov after notifying law enforcement.

7. Support the family through the process

This is demanding work. Rotate practical tasks, protect time for food, sleep, and child care, and keep a list of who is handling records, media requests, and investigator contact. NCMEC can connect families in missing-child cases with peer support and counseling referrals. The Department of Justice Office for Victims of Crime maintains a directory to help locate victim-service programs and resources.

If you or someone close to the case is in emotional distress or thinking about self-harm, call, text, or chat 988 in the United States for the 988 Suicide & Crisis Lifeline. If there is immediate danger, call 911. Asking for support does not distract from the search; it helps people continue making careful decisions.

A steady next step

In the first hours, the goal is not to solve the case alone. Make the local report, preserve accurate details, use the official resources that apply, and coordinate every public action with investigators. Keep information private unless release serves the search, verify every urgent claim, and accept support. Those measured steps give professionals and the family the clearest possible foundation for the work ahead.
