Not sure where your pet's chip is registered?  Visit the AAHA Universal Pet Micropchip Lookup Tool at PetMicrochipLookup.org.

To update your pet's registration, you'll need your pet's microchip number.  If you haven't already created an account with the manufacture, you'll need to do that as wel so you can accress the registration in the future to update the information.  Make sure all of the information, particularly your phone number(s) and address, is correct.
