Agree with Jackie.
Microchip is not a GPS gadget and can’t track your pet on the if it gets lost. But chances are still there that when a pet is found and taken to a shelter or veterinary facility, one of the first things they do is scan the pet for a microchip. On the chance that they discover a microchip, and if the microchip registry has correct data, they can rapidly discover the pet’s holder.
