Enter the microchip number here to search the PetLink database.


This search is used to find lost and found pets, and will return pet information for microchips registered with PetLink. This search also utilizes the AAHA Universal Pet Microchip Lookup Tool to search other U.S. based microchip registries.

The AAHA Universal Pet Microchip Lookup Tool will not return pet owner information contained in the registries’ databases since it is only a lookup tool.  Instead it will identify which registry should be contacted when a lost pet is scanned and a microchip number is identified.

If the pet could possibly originate outside the U.S. you may want use the PetMaxx search engine which searches more than 32 international microchip registries to determine if the pet has been registered in another country.

How to Find Your Pet’s Microchip

There are a couple of options for locating your pet’s microchip number. You can simply locate the barcode sticker or microchip registration you received from the veterinarian who placed the microchip or from the animal shelter the pet was adopted from. If you no longer have any documentation containing the microchip number, bring your pet to a veterinarian or animal shelter and have them scan the chip.

Microchip Input Search Results

Using PetLink’s pet microchip lookup is very simple. All you need to do is enter the microchip number in the search box. The results will show your pet’s name, species, breed(s), gender, and color(s). 

The lookup tool also allows you to report a found pet. The form requires the date found, type of finder, finder name, email, and phone number. You will also need to report the organization, the physical state the pet is found in (injured, uninjured, etc.), and the pet’s location.

Importance of Pet Microchips

Microchipping your dog and pets is crucial to keeping them safe. Without a microchip, identifying found animals relies solely on physical characteristics and the presence of a collar/tag with its owner’s information. Unfortunately, it is very common to find pets without tags. This often leads to pets being placed in shelters, hoping their owner will find them. When a pet has a microchip, it can be scanned by a veterinarian or animal shelter, regardless of the condition the pet is in. Microchips in cats and dogs are the quickest and easiest way to identify lost animals and return them to their owner. By reuniting lost pets with their owners, microchips directly impact and reduce the number of cats, dogs, etc., that have no choice but to be placed in shelters.     


Pet Microchip FAQs

What is a pet microchip?

A pet microchip is a tiny, scanable transponder implanted into a pet’s skin by a quick injection performed by a veterinarian. Microchips are used to identify a pet and retrieve both owner and pet information to return lost animals.

Are microchips already registered?

Pet owners are required to register their pet’s microchip with their information. Click here to register a microchip with PetLink. 

How does a pet microchip work?

Microchips are assigned a unique identification number. A veterinarian or animal shelter professional scans the chip to relay this ID number, which is then used to search a database. The database will show the pet’s information as well as their owner’s information.

Is a microchip the same as a GPS tracker?

A Microchip is not a GPS tracker. It cannot locate an animal’s precise location. Microchips do not require a power source. They only provide an identification number when scanned using a separate scanning tool.   

Can a microchip be removed or tampered with?

Microchips are considered a safe and permanent solution to identifying lost pets. 

When the microchip is professionally implanted, it cannot be tampered with. A veterinarian could surgically remove a microchip, but there is typically no reason for this to be required.
