Pet Microchip Lookup Tool


AAHA Universal Microchip Lookup Tool

The AAHA Universal Pet Microchip Lookup Tool is NOT a microchip registry—it is an internet-based application to assist in the identification of those registries on which a particular microchip is registered, or otherwise provide the chip’s manufacturer. The tool works by searching the databases of participating companies. It will not return pet owner information contained in the registries’ databases, instead it will identify which registries should be contacted when a lost pet is scanned and a microchip number is identified.)

The American Animal Hospital Association does not maintain a database of microchips of its own. To register a microchip or update contact information for a microchip, pet owners should contact their pet recovery service. AAHA is unable to assist pet owners with their microchip registration and/or problems.

What is a microchip?

HomeAgain microchip is your pet’s permanent ID. A pet microchip is the size of a grain of rice and placed under your pet’s skin between the shoulder blades. This chip can never be removed or become impossible to read. The scanner uses this ID to contact you and reunite you with your pet.

How much does it cost to microchip your pet?

According to, the average cost to have a microchip implanted by a veterinarian is around $45. This one time fee includes the registration into the database.

If you adopted a pet from a shelter or rescue, please note that your new pet will likely already come with a microchip. Be sure to ask.

Are microchips GPS tracking devices?

No. They are radio-frequency identification (RFID) implants that provide permanent ID for your pet. Because they use RFID technology, microchips do not require a power source like a GPS. When a microchip scanner is passed over the pet, the microchip gets enough power from the scanner to transmit the microchip’s ID number. Since there’s no battery and no moving parts, there’s nothing to keep charged, wear out, or replace. The microchip will last your pet’s lifetime.
