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.

Yes, the 15-digit pet microchip is the international standard (see ISO 11784:1996 and ISO 11785:1996). If you travel to or move outside of the United States with your pet, consider having a 15-digit microchip implanted. ​

However, in the U.S., the Animal Welfare Act does not authorize the USDA-APHIS to regulate private pet ownership and concluded that it cannot mandate a national standard for pet microchips or scanners. Therefore, in the U.S., there are multiple microchip companies with multiple scanners, multiple radio frequencies, and multiple registration databases.

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.

A “failed search” means that the registry could not be checked for the microchip you entered. This is out of AAHA’s control, and you will want to try your search again at a later time.

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.

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.
