This will prevent a burglar from loading your valuables into a vehicle in the seclusion of your garage. Be sure to lock all vehicles you're leaving behind. Mark your valuables with Operation Identification. The number you engrave on your property makes it identifiable to law enforcement officials anywhere in the United States. Although serial numbers theoretically do the same thing, many people don't keep records of the serial numbers on their valuables.

You can sign up for your free Operation Identification kit at your local Police Department. If you'll be driving, try to load your vehicle in the attached garage to avoid advertising to passersby that you are leaving.

Use only your initials and your business address on your luggage tags.
