Instructions
Find out what company manufactured the microchip that's implanted in your pet. You can determine this by asking whoever implanted it, such as your veterinarian or the shelter where you adopted your pet. If you are unsure who implanted it, or are not even sure whether your pet has a microchip, most veterinarians and animal shelters will have the technology to scan your pet and retrieve the information you need.
Contact the manufacturer of the microchip directly. You can ask your vet or local shelter for the contact information, or you can find it on the manufacturer's website. Ask the manufacturer if they or another company keeps track of the information found on microchips. Sometimes manufacturers outsource this job to a third-party company.
Contact the third-party company or correct department of the company that manufactured the microchip to update your contact information. This contact information for the correct company or department will be provided by the manufacturer of the microchip. Be sure to supply your updated contact information through the proper format. You may be required to mail in a contact update form, or you may be required to fill out a form on their website. The information for how to find this form will be provided to you over the phone. Be prepared to pay a fee; some companies offer varying rates, with a discount for lifetime coverage.
How to Update a Microchip
Pet owners want to make sure their pets are always safe and secure. Sometimes, this can be accomplished using the latest in pet technology. You now have the option of having the veterinarian implant a microchip just under your pet's skin, usually between the shoulder blades. This microchip contains your contact information, which can be read by any shelter or vet's office that happens to end up with your pet should it ever get lost. To ensure your pet's ongoing safety, you need to update the microchip if your contact information should ever change.
