How do I check if a microchip already has a registered owner

How do I check if a microchip already has a registered owner?

Enter the microchip number in the Microchip Lookup tool at the top of petlink.net — if the chip is registered, the pet's name and owner details will appear.

If the number is correct, your vet, shelter, or rescue may have already registered your pet for you. Go to https://www.petlink.net/account/forgot-username/ and enter your pet's microchip number to find the account and receive a code in the email registered.
