Abstract: Systems and methods for integrating, managing and using electronic and tangible data relating to animals, especially data corresponding to official documentation. A secure, centralized repository for storing animal characteristic information, owner information, health information, official status information and the like is provided that may be used by a multiplicity of different user classes. Tangible counterparts of the electronic data also are provided, including documentation as well as fixtures that may be attached to an animal. A unique animal identification code is stored in the database and preferably appears on the tangible counterparts. The code serves as a primary key with respect to an animal's electronic records and allows records to be easily associated with a particular animal.
