Marking animals with a microchip is the most durable, effective and completely safe method of quick and reliable identification. Every transponder (chip) has a unique number which enables instant identification of the animal and its owner, helping them reunite faster. However, it is important to remember that a chip is just a transponder with an encoded number. It is not a tracking device and contains no data about the animal or the owner!
 
Therefore, in order to identify a chipped dog or cat, it is necessary for a microchip to be registered in a national marked animal database and that all the necessary data is provided during the registration process. The chip's unique number is then assigned to the pet's owner, enabling identification and instant contact. By registering your pet in a database, you give it an identity. It is important that the data you enter is accurate and always up to date. Providing your current phone number is the most important part, as that is the preferred way of contacting registered members. MyMicrochip.org unites national databases from around the world, making identification global.

This means that you do not need to know which database the dog, cat or other pet you've found is registered in.  

This solution facilitates quick and accurate identification of abandoned, lost, found or stolen animals, thus helping combat animal homelessness.
Animal identification using microchips is the most reliable, safe and durable method of animal marking. Unlike other popular methods (such as tattooing), it is impossible to forge or remove the marking, owner data is easy to verify and microchip numbers are completely unique.

Registering electronically marked animals is a reliable and effective method of identification used around the globe, and is recommended for all owners and breeders who care about their animals.
