There are several web sites (Child Shield, USA and Code Amber to name two) and many published documents relating to the prevention of child abductions. However, these are a few of the things that we felt applied to our situation: Memorize your license plate number, or know where it can be found in your files, quickly. For us, not knowing the license plate number delayed the police by over a half-hour - precious time when you're searching for a missing child. Keep a record of your car's vital statistics - make, model, year, VIN number, etc. - in your wallet or someplace outside of the vehicle. Have family pictures taken on a regular basis. If your child wears glasses, take an occasional photo of them without their glasses. Know where current photos and/or videos can be found for police and the media. Carry a current photo of each child with you. Have your child fingerprinted and/or have a DNA sample taken. There are numerous organizations that perform these services, many of them at no cost to you. If you carry a cell phone in your car, keep it on. If your cell phone is on, the police may be able to track it to get an approximate location. In our case, the cell phone was off and in Grandma's purse, so it didn't help. Know what credit cards you are carrying so if they are stolen with your vehicle, you will be able to report them. You may want to consider installing an electronic tracking system such as Lo-Jack, which allows the police to track the vehicle if it's reported stolen. GM's OnStar system could also be a life saver in a car-jacking or abduction situation.
