Combined with a collar and current name tag, a microchip increases the likelihood of a lost pet being safely reunited with its owner. However, even with a microchip scanner, identifying the correct pet recovery registry to contact can be challenging because microchip manufacturers and pet recovery services use different microchip technology and databases.

To alleviate the guesswork for veterinary hospitals, animal control facilities and shelter staff members, the American Animal Hospital Association (AAHA) created the AAHA Universal Pet Microchip Lookup Tool. The tool is possible through an unprecedented collaboration between the participating microchipping and pet recovery companies. Although the launch of this tool represents a ground-breaking achievement for those working to reunite lost pets with their owners, AAHA acknowledges that the tool is a work in progress and will periodically review its functionality.

AAHA provides an internet-based application that enables veterinarians, humane organizations, pet owners or other persons to search various Pet Recovery Service registries and identify those registries on which a particular microchip is registered. AAHA is not affiliated or involved with any specific microchip registry and has no relationship, financial or otherwise, with this Participating Pet Recovery Service Registry (“Registry”). This Registry has given AAHA permission to search the Registry’s database in order to assist pet owners in being reunited with their pets. AAHA does not maintain a database of microchips of its own. It only links to registries such as this one. The AAHA Universal Microchip Lookup Tool only searches the databases of companies that elect to participate in the program.

The AAHA Universal Pet Microchip Lookup Tool works by checking the databases of the Participating Pet Recovery Service registries to determine which has registration information available for a microchip. Once a microchip identification number is entered into the tool, a list of all the registries with microchip registration information available, along with the registries’ contact information, appears in chronological order with the registry with the most recent update appearing first. If the microchip has not been registered with any Pet Recovery Service Registry, the result returned will default to the microchip’s manufacturer or distributor. While the tool will not return the pet owner information contained in the registries’ databases, it will identify which registries should be contacted when a lost pet is scanned and a microchip is found.

Since the tool works by checking the databases of participating pet recovery services to determine which has registration information available for a microchip, pet owners should contact their pet recovery service. The American Animal Hospital Association will be unable to assist pet owners with their microchip registration and/or problems.

To protect the privacy of pet owners, the tool will display all the registries with microchip registration information available, along with the registries’ contact information. The information will appear in chronological order; the registry with the most recent update appears first. Additionally, the pet recovery services have trained experts, resources and infrastructure to efficiently and effectively contact the owners of lost pet.

Microchip technology and regulations can vary by countries. The AAHA Universal Pet Microchip Lookup Tool was created to primarily serve chips distributed in the United States.

The tool has been unanimously endorsed by the Coalition for Reuniting Pets and Families. Members of the coalition include: AAHA, American Humane Association (AHA), American Society for the Prevention of Cruelty to Animals (ASPCA), American Society of Veterinary Medical Association Executives (ASVMAE), AVMA, Humane Society of the United States (HSUS), National Federation of Humane Societies (NFHS), and the Society of Animal Welfare Administrators (SAWA).

AAHA and the Coalition for Reuniting Pets and Families encourage all veterinary practices, shelters and animal control facilities to bookmark or link to www.petmicrochiplookup.org, and use it every time a lost pet is scanned.
