Make an appointment with your veterinarian for microchipping if your pet isn’t already microchipped (then make sure that your pet’s chip is immediately registered).
Check your already-microchipped pet’s registration information in the microchip manufacturer’s database, and make sure it’s up-to-date.
Updating your pet’s microchip registration
To update your pet’s registration, you’ll need your pet’s microchip number. If you haven’t already created an account with the manufacturer, you’ll need to do that as well so you can access the registration in the future to update the information. Make sure that all of the information, particularly your phone number(s) and address, are correct.
There are many databases that allow you to register your pet’s microchip, but the one that really counts – the one that animal shelters and veterinarians will search – is the database maintained by the manufacturer of your pet’s microchip. AAHA’s Universal Pet Microchip Lookup Tool is linked to the registries of the majority of microchip manufacturers and allows a quick database search of any microchip made by these manufacturers. In addition, a number of public microchip registries have also been linked to the AAHA Universal Pet Microchip Lookup Tool to make it easier to find a microchip’s registration.
