How to Update Your Pet’s Microchip Details
A microchip is a permanent form of identification, but the contact record linked to its unique number can become out of date. It is not a GPS tracker and cannot show a pet’s live location. If a pet goes missing, a scanner can identify that number and authorised organisations can use the linked registry record to try to contact the owner. Keeping that record current gives a lost pet a better chance of being reunited with home.
It is worth checking the details after a move, a new phone number or email address, or a change of ownership. Make this part of the to-do list when life changes, rather than waiting until your pet is missing. If your pet is also registered with a local council, check separately what information that registration needs: council registration and the microchip registry record are separate records.
Find the registry that holds the record
Start with your pet’s microchip paperwork, adoption documents or previous registration correspondence. These may name the registry and show the microchip number. If you have the number but do not know the registry, Pet Address is a public search tool that can direct you to a participating database. In Victoria, government information also lists registries licensed to accept dog and cat records.
Do not assume every search result will answer every situation. Registry arrangements can differ, and records for some pets may not be found through a particular search. If you cannot locate the number or registry, contact your veterinarian, local council or an animal welfare shelter to ask whether they can scan your pet and help identify the next step.
Update the details with the registry
Once you have identified the registry, contact it directly and follow its current change-of-details or change-of-ownership process. If your pet changes hands, the new owner should make sure the registry receives the transfer and current contact details. Check the spelling of your name, your mobile number, email address and home address before submitting the update. Where the registry allows it, consider whether a second reliable contact person would be helpful if you cannot be reached.
Keep a copy of the confirmation and the microchip number with your pet’s important documents. This can save time if you move again, transfer ownership, or need to check the record later. If you are moving interstate, contact the registry and the relevant local authority to confirm what needs updating; registry pathways and local requirements can vary.
Why current information matters
A microchip cannot help someone reach you if the phone number or address attached to it is no longer yours. Veterinary clinics, councils and animal shelters may scan a found animal; an accurate registry record is the link between that number and an owner who can be contacted.
Updating the record is a small job, but it is useful preparation before travel, a house move or an unexpected separation. It complements—rather than replaces—safe containment, current identification tags and a plan for what to do if your pet is lost.
Frequently asked questions
Do I need a new microchip when my contact details change?
Usually, the update concerns the registry record linked to the existing microchip number. The registry can tell you if it needs any particular information or documents.
What if I do not know my pet’s microchip number?
Ask a veterinarian, council or animal welfare shelter whether they can scan your pet. The number can then help you identify the relevant registry.
