One option is to use your social security number since it can be traced by humane shelters. Of course, you may not be comfortable with your social security number floating around on a lost dog.
Microchipping is done by your veterinarian. A microchip about the size of a grain of rice is implanted by injection between the dog's shoulder blades. The microchip has its own code and can be scanned by humane societies to locate you. Most dog microchip scanners will work with other microchip brands and related registries. When your dog is microchipped, you will also receive a dog tag that says so. Because there is no discomfort to the animal, this is considered a safe and efficient method of dog identification.
