Microchipping and Registration in Australia: The Basics
A microchip is one of the most important pieces of kit your dog will ever have, yet it only works if the details behind it are kept up to date. This guide explains what a microchip actually does, how to transfer ownership when you bring a puppy home, and why council registration is a separate job entirely.

What a Microchip Is (and Is Not)
A microchip is a tiny electronic implant, about the size of a grain of rice, placed under the skin between your dog's shoulder blades. When a vet, pound or rescue scans it, the chip returns a unique 15 digit number. That is all it does. It is not a GPS tracker, it does not store your address on the chip itself, and it cannot tell anyone where your dog is right now. It is simply a permanent ID number that cannot fall off the way a collar tag can.
The number only becomes useful when it is matched against a registry database that links it to your name, phone number and address. Most puppies from responsible breeders are microchipped before they go to their new homes, and in most parts of Australia microchipping is a legal requirement, though the details vary by state, territory and council, so check your local requirements.
The Registry Matters More Than the Chip
Here is the part many owners miss: the chip is only half the system. A perfectly implanted microchip attached to a disconnected phone number or an old address is close to useless. Pounds and shelters regularly scan lost dogs, find a chip, and then hit a dead end because the contact details on the registry are years out of date.
Whenever you move house, change your mobile number or change your email address, updating the microchip registry should be on the same to do list as updating your electricity account. Your vet can scan the chip and tell you the number and which registry it sits on if you have lost the paperwork.

Transferring Ownership from Your Breeder
When you bring a puppy home, the microchip will usually be registered to the breeder. Transferring it into your name is your job as the new owner, and it is worth doing in the first few days, not the first few months. A good breeder will make this easy for you. They should provide:
- The microchip number, usually on a certificate or in the puppy's paperwork
- The name of the registry the chip is listed with
- A signed change of ownership form, or confirmation they have started the transfer online
If a breeder cannot tell you the chip number or which registry it is on, treat that as a warning sign and ask more questions before committing. Our guide to selecting the right breeder covers the other paperwork you should expect, and you can read what other owners have experienced with individual breeders on our breeder profiles. Remember that reviews reflect the opinions of individual reviewers, so use them as one input alongside your own checks.
"A microchip with outdated contact details is like a letterbox with no house behind it. The chip is permanent, but it is your details that bring a lost dog home."
Council Registration Is a Separate Thing
This trips up plenty of new owners: microchipping your dog and registering it with your local council are two different obligations. The microchip registry is about identification and reunification. Council registration is about your local government knowing which dogs live in its area, and it typically comes with an annual or lifetime fee and a registration tag for the collar.
Having one does not mean you have the other. In most areas you need both, and councils often ask for the microchip number and proof of desexing when you register. The rules, fees and deadlines vary by state, territory and council, so check your local requirements as soon as your puppy comes home. Desexed dogs usually attract lower registration fees; if you are weighing up the timing of desexing, talk to your vet about what is right for your dog's breed and age.
Your First Fortnight Checklist
Here is a practical list to work through in the first two weeks with your new dog:
- Confirm the microchip number matches the paperwork: ask your vet to scan it at the first health check
- Complete the change of ownership with the microchip registry so the chip points to you, not the breeder
- Double check every detail on the registry: phone, email, address and an emergency contact if the registry allows one
- Register your dog with your local council and find out when renewals fall due
- Attach the council tag and an ID tag with your phone number to the collar, because a tag gets your dog home faster than a chip scan
- File the microchip certificate, registry login details and council paperwork somewhere you can actually find them
- Set a reminder to update the registry and the council whenever you move or change numbers

None of this is glamorous, but it is the admin that reunites thousands of lost dogs with their families every year. Sort the transfer, keep your details current, and register with your council, and you will have covered the basics that matter most.
