Microchips are a great, permanent form of identification, however; microchips are only effective if they have been registered with a microchip registry
If your pet is microchipped, be sure the microchip is registered and the information is kept current
Most major microchip manufacturers allow information to be updated free of charge, regardless of membership status. Additionally, Found Animals Registry is a free microchip registry. Any brand of microchip can be registered with Found Animals. Visit their website at www.foundanimals.org
