If a child goes missing:
• If your child is missing from home, search the house checking closets, piles of laundry, in and under beds, inside large appliances and inside vehicles, including trunks — wherever a child may crawl or hide.
• If you still cannot find your child, immediately call your local law enforcement agency.
• If your child disappears in a store, notify the store manager or security office. Then immediately call your local law-enforcement agency. Many stores have a Code Adam plan of action — if a child is missing in the store, employees immediately mobilize to look for the missing child.
• When you call law enforcement, provide your child’s name, date of birth, height, weight, and any other unique identifiers such as eyeglasses and braces. Tell them when you noticed that your child was missing and what clothing he or she was wearing.
• Ask that your child’s name and identifying information be entered immediately into the National Crime Information Center Missing Person File.
• After you have reported your child missing to law enforcement, call the National Center for Missing & Exploited Children at 800-THE-LOST (800-843-5678).
