Dog Microchipped but Missing? What To Do...


Microchipped but Missing? The Critical Step Too Many Pet Owners Forget

As National Microchipping Month reminds us this June, it’s not enough to chip your pet. Keeping those details up to date could be the difference between lost and found, writes Caroline Zambrano, Pet Journalist.

When Eliza Kennedy’s dog Mazzy wriggled through a loose section of fence in her Brisbane yard, she had no idea how quickly things could spiral. The one-year-old Australian Shepherd wasn’t wearing her ID tag at the time — it had recently fallen off her collar. By the time Eliza realised she was missing, the curious pup was already several blocks away!

Thankfully, Mazzy crossed paths with a dog walker, Daniel Da Rocha Silva, who spotted her while out on his rounds. Daniel immediately posted Mazzy’s photo in the local Facebook community group and took her straight to the nearest vet to have her microchip scanned.

The search for missing Mazzy was cut short thanks to her microchip & up-to-date registry details

In the meantime, Eliza was frantically searching for Mazzy in the neighbourhood until a neighbour spotted the Facebook post and let her know. But by then, the microchip (linked to Eliza’s contact information) had done its job!

“When the vet called me, Daniel was still there and close enough to bring her straight home,” said Eliza. “I was flooded with relief and gratitude! We think our dogs are secure, that their tag is in place, that they won’t run … but if the worst happens, microchipping means the best chance of getting them home.”

In a sweet turn of events, Daniel has been Mazzy’s dog walker ever since!

June is National Microchipping Month — a timely reminder for Australian pet owners to not only microchip their animals, but to also check, update and verify that the information linked to that chip via a registry is accurate and accessible.

So, what exactly is a microchip and how does it help bring pets home? A microchip is a small rice-grain sized chip that is placed just below the skin in the back of the neck of dogs and cats. It causes no discomfort, but can speak volumes when it matters the most!

Microchipping dogs and cats is mandatory [1] in every state in Australia except Northern Territory (although it is required within the City of Darwin). Your pet’s microchip could be registered on one of seven microchip registries currently active in Australia – five private and two state government-run.

  • PetCloud (not currently recognised under Australian microchip registry legislation)

Pet owners can choose to register their pet with more than one registry for added peace of mind. However, this applies in all states except Victoria where legislation states that a microchip can only be registered with one registry.

To tell which register your pet is on, you can use Pet Address, the online search tool that allows vets, shelters/pounds and pet owners to look up microchip numbers across the established private registries – excluding the two government-run registries.

Newly launched microchip registry

PetCloud Microchip Registry is newly launched by Australian pet management platform PetCloud, combining microchip registration with the company’s growing network of pet professionals, breeders, veterinarians and councils. 

In a press release, Deb Webber, CEO of PetCloud, stated, "We're proud to launch a first for Australia — Pet Management platform, plus a Microchip Registry where pet owners are in control and their data is easily kept current through a simple, opt-in process.

"Lost pets are a national issue — and outdated contact details in microchip registries make reunions harder. Many pet owners don't even know which registry their pet is on. We're giving Australians a convenient, simpler way to manage their pet's microchip info and get found faster when every second counts."

While the platform aims to simplify the microchip management process and empower pet owners, there are some important limitations to be aware of during this early stage.

PetCloud Microchip Registry is not listed in the current Australian legislation as one of the compliant registries under the relevant state and territory laws. This means PetCloud Microchip Registry is not integrated with Pet Address – so if your pet’s microchip is registered exclusively with the company, it will not appear in a Pet Address search.

Watch out for microchipping scams!

More urgently, pet owners are being warned about scams targeting microchip registrations!

Watch out for an international pet scam run by a group called Petchip, which preys on pet owners by sending fraudulent emails asking for payment for “microchip registration expiration”. The emails include a threat that pets will be listed as “unregistered” if a fee is not paid.

Concerns around microchip security don’t stop at scams. 

Earlier this year, the sudden collapse of the once-operational West Australian-based microchip registry, HomeSafeID, left thousands of pets at risk of becoming untraceable. 

The shutdown also highlighted broader issues with Australia’s pet identification system, including inconsistent state registry rules and the all-too-common problem of outdated owner contact details.

To explore how these issues impact pets and their families, and what pet owners can do to better protect their animals, I reached out to veterinarian Dr Bronwyn Orr, former President of the Australian Veterinary Association (AVA) and founder of Pawl, a veterinary technology company focused on preventative health. 

Based in Canberra, Dr Orr also operates an after-hours urgent care clinic and provides consulting and lecturing services to the veterinary profession.


Also contributing is Fra Atyeo, Operations Manager at Bendigo Animal Relief Centre (BARC) in Victoria, who brings frontline perspective from one of the busiest council-funded pounds in the state, also operating as a shelter, providing animal adoptions both locally and interstate. 

Their message is clear: microchipping is just the first step. What you do next could be the reason your lost pet makes it home!

Importance of microchipping

“If your pet goes missing, their microchip is the crucial link in bringing them home,” said Dr Bronwyn. 

“Vets and shelters can scan the chip, search the state or national registries, and quickly access the owner’s contact information. Pets with microchips are far more likely to be reunited with their families than those without.

With reuniting missing pets with their families a priority, Fra sees the results of scanning microchips first-hand every day at BARC, the council-funded pound service for the City of Greater Bendigo that provides shelter, food and medical treatment to animals who have become lost, seized or surrendered each year.


“Rangers in Bendigo scan dogs they collect before bringing them to BARC, and if the pet’s microchip details are up-to-date, there is a good chance these pets can be returned to owners by the rangers right away!” she explained.

“In the past five months, Council Rangers have returned over 50 dogs directly to their homes. If the Ranger is unable to get the owner on the phone right away, they bring the dog to BARC, and we follow up with more phone calls and emails.”

It’s also not uncommon for someone to walk into BARC with a dog they’ve just found wandering in their street.

“We scan the pet and call the owner within minutes of the pets’ arrival. Sometimes the owner comes straight in to collect them, and the dog never even makes it to a kennel. They hang out at reception with the staff waiting for their lift back home!” said Fra.

At the time of interview, BARC had four stray dogs in care without microchips. A further three stray dogs had microchips which link back to the breeder or a previous owner who no longer owns the dog.


All dogs with up-to-date microchips were already reunited with their owners. “None of them spent last night in the shelter. They were all at home with their families, where pets belong,” said Fra.

These cases are far from isolated — in fact, BARC’s data paints a clear and alarming picture. Fra reviewed a sample of the last 250 stray animals that came into their care and found that 64 (25%) had no microchip at all. Of the 186 animals that were microchipped, a staggering 76 – more than 40% - had outdated information that did not lead to their owner!

“Only 110 (44%) of the 250 stray animals had microchips with current information linked to them,” said Fra. 

“Keeping pets microchip details up to date is just as important as the ‘chip itself!”

The B.I.G. problem with outdated microchips

One recent arrival at BARC highlights the risk of outdated microchip details — a big, friendly boy nicknamed ‘The B.I.G.’, described as a loveable goofball who knows some cool tricks!

“We have called him ‘The B.I.G’ because we don’t know the name his family gave him,” said Fra. “He came into our care with a microchip, but it still had the breeder listed as the owner, and unfortunately, they were unable to tell us who they sold this dog to.

“His owners probably assumed he was microchipped to them, and someone would call them if their pet was ever found. We find this happens a lot, and many people don’t actively look for their pet when they go missing. This is an example of how microchips only work if they are up to date!”

Unfortunately, The B.I.G.'s story is far from uncommon. More than half of the microchipped pets that come into BARC’s care have outdated information, making it difficult — and sometimes impossible — to track down the owner.

“Most people are very surprised when we finally track them down and tell them that their microchip details are out of date,” said Fra. 

“The responsibility is on the owner of a pet to update the microchip, not the breeder, the person you purchased the animal from or your vet.”

Fra advised all dog and cat owners to record their pet’s microchip number and the registry it is listed in a safe place, and get into a routine of checking your details and alternative contact’s details at least once a year.

“Check your smoke alarm, check your pet’s microchip! If you don’t know your pet’s microchip number or registry, ask your vet or local shelter for help,” she said.

But keeping details up to date is only part of the challenge. For many people, getting their pet microchipped in the first place can be more difficult than expected. Fra explained that cost remains the biggest barrier to microchipping, followed closely by access and transport.

“Some vets will require an owner to obtain a Register Source Number under Victorian legislation, which has additional costs to getting a microchip,” she said. 

“Many people also have pets who don’t travel well and may arrive at a vet clinic quite agitated. I think we can all appreciate how nervous our pets can get at veterinary clinics. Being able to take your dog to the local dog park for his microchip is much more convenient.”

Making microchipping easier and free

To tackle these barriers, BARC launched a free microchipping program in 2021.

“Our goal is to make microchips accessible to everyone, and one of the biggest ways we can do this is by removing the cost barrier,” said Fra. 

“We also run microchipping events at other locations, such as dog parks, livestock sale yards (to reach the working farm dogs) and community houses in rural areas so that we can help people who may not have the ability to transport their pet to our shelter.”

BARC has provided more than 1,000 free microchips to pets in the local community!

While grassroots efforts like BARC’s are helping remove practical barriers, and organisations like CAR and AAR send reminders to update details, confusion around microchip registration persists. 

Dr Bronwyn said many people mistakenly believe council registration and microchip registration are the same thing, and that their details are automatically updated.

Daniel Wyld, Managing Director at Global Micro Animal Registry, agrees that education is a major gap in the current system.

“One of the biggest challenges in pet identification is lack of awareness and education,” he explained. “The microchip must be registered with a recognised registry and the owner’s contact details must be kept up to date. That doesn’t always happen, and when it doesn’t, it increases the risk of a pet not being returned.

“There are also multiple registries across different states, with slightly different processes. This can cause confusion, not just for pet owners, but also for vets, breeders, councils and rescue groups. When people aren’t sure what to do, it’s easy to put it in the “too hard basket”, which puts pets at risk.”

Despite the challenges, Daniel sees real potential for improvement through national coordination.

“The biggest opportunity, I believe, is to create a single national educational resource – a clear source of truth for everyone, no matter where they are,” he said. “This would also help with things like puppy farming and online scams involving animals. Most registries, including national ones like ours, already contact their users to confirm or update details, but a more coordinated national effort would improve things further.”

Daniel’s call for a unified national education effort echoes broader concerns about inconsistency within the system – concerns also shared by veterinary professionals and leaders involved in companion animal policy.

Microchipping lacks national oversight

Despite microchipping being compulsory for cats and dogs, “animal microchip registries are not governed by a national set of laws or guidelines, and instead each state has to try and grapple with the private registries themselves. It's why NSW and South Australia have created their own registries,” Dr Bronwyn explained.

“We need avenues at the national level to discuss companion animal issues, and currently outside of the Animal Health Committee or Australian Animal Welfare Strategy (AAWS), there aren't any structures that facilitate this. The federation strikes again!”

To better understand the likelihood of reform, I contacted the Animal Health Committee (AHC), which operates within the Australian Government Department of Agriculture, Fisheries and Forestry (DAFF). In response to a request for comment on whether national oversight or reform of microchip registry systems is being considered, a spokesperson for DAFF said:

“The principal objective of the Animal Health Committee (AHC) is to maintain and improve animal health outcomes, manage animal biosecurity risks and facilitate trade through national leadership, strategic direction and collaboration with stakeholders. AHC is not considering national oversight or reform of microchip registry systems, as it falls outside the scope of AHC responsibilities. The management of pet microchip registry systems within a state or territory, including any potential reforms, falls within the remit of the respective state or territory government.”

To Dr Bronwyn, an ideal system for pet microchip management in Australia would be a national set of guidelines, agreed upon by all states and territories, giving states a common framework to follow.

“Outside of a national microchip registry like they have in New Zealand, the next best thing would be at least a backup being available to governments and agreed operating guidelines,” she said. 

“There would be real benefits to a national, government-owned microchip registry, however given the lack of companion animal leadership at a national level in Australia, the reality is, this is a far off dream.”

Dr Bronwyn anticipates that more states will follow NSW and South Australia’s lead by launching their own registries – a move that, while practical, could create further complications.

“This has unintended consequences for pet owners, however, given that some states don't readily allow vets and shelters to access their registry if they are interstate (e.g. ACT vets or QLD vets accessing NSW registry),” she said.

Fra also wishes for a more unified system, but added that stronger government oversight alone isn’t enough to prevent registry failures like HomeSafeID.

“If a private company is in the process of collapse and chooses to keep it private and not warn their customers, I’m not sure increased government oversight would make any difference. However, I do believe there should be a better system in place which would minimise the fallout,” she said.

Fra’s vision aligns with Dr Bronwyn’s: a single, government-managed database that consolidates all microchip records into one central, accessible and secure platform. Currently, vets, shelters and pounds require accounts with all the different registries in order to manage microchips. Pet owners may also require different accounts for different pets.

“They may have a cat microchipped with AAR, a dog microchipped with CAR and a retired Greyhound microchipped with Greyhound Racing Victoria. If this owner needs to update their details, that’s three different companies they need to contact, follow three different processes, and potentially pay three different sets of fees,” said Fra.

“If the government managed everything from a central database, it would streamline the process for vets, shelters, pounds and breeders as well as for owners of the pets.  

“An easy process will mean less mistakes and errors, and greater compliance, resulting in more up-to-date microchips! In addition, a government database would be safer than a private one from collapse or closure.”

Key message to pet owners during National Microchipping Month  

Dr Bronwyn’s key message to pet owners this National Microchip Month is to check your pet's microchip details are up to date.

“If you ever change your phone number, you MUST update your pet's microchip details, as that is the primary way shelters and vets will reunite you with your pet!” she added. 

Also, next time you visit the vet, ask them to scan your pet’s microchip and confirm that the number matches what’s listed on the registry, Daniel suggested.

“Mistakes can happen, and even a small error can stop a pet from being returned home,” he said. “Check your pet’s microchip details todayContact your registry and make sure your phone number and address are correct. It only takes a few minutes, but it could make all the difference if your pet goes missing.” 

Reinforcing the broader message behind National Microchipping Month, Dr Bronwyn reminded pet owners that microchipping is not only a legal requirement but also “the smart thing to do.”

“You can now link your pet's history with their microchip through companies like Vedi, and there are thermal microchips which allow your pet's temperature to be taken with just a scan. These advancements are unlocking the potential of your pet's microchip,” she said.

But while technology is advancing, the heartache of a missing pet hasn’t changed.

“Losing a pet is a gut wrenching feeling and never having them come home is even worse,” said Fra. 

“Don’t take the risk. Get your pet a microchip and check your details regularly. It’s a very small price to pay to have your pet reunited with you.”

And if you think your pet will never get lost, think again, she cautioned.

“I would say that EVERYONE who has lost a pet without a microchip has thought this, and they were all mistaken!” said Fra. “Right now, in Bendigo, nearly 17 owners a month lose a pet they thought they would never lose. If 17 people in our community were winning the lotto every month, I would be liking those odds and buying quite a few tickets!”

Northern Territory [8]

Microchipping is not legally required across NT, except in City of Darwin, where it is mandatory. Where required, pet owners must register with a national registry.


To tell which register your pet is on, simply hop on to 
Pet Address and enter in your pet’s microchip number.  Pet Address is a search engine that allows you to search for the microchip number of a pet in various animal databases. It’s not a registry.

Pet Address only searches the databases of private microchip registries — it does not include the government-run registries in New South Wales and South Australia. So, if your pet’s microchip doesn’t show up on Pet Address, it may still be listed with a state-based registry.

What happened to HomeSafeID?

In early 2025, HomeSafeID — a private microchip registry once used by thousands of pet owners across Australia — ceased operations without formal public notice. While its online search function remained temporarily active, the company stopped processing updates or new registrations.

This meant that pet owners could no longer update their contact information, new microchips couldn’t be registered with HomeSafeID, and existing microchips became increasingly at risk of being untraceable if the website went offline.

To avoid losing access to important microchip data, the Victorian government secured HomeSafeID’s database and eventually transferred management to one of Australia’s largest national microchip registries, Central Animal Records (CAR).

CAR is now responsible for managing all new microchip registrations previously intended for HomeSafeID, updates to existing records and the ongoing ability to search and access owner details.

If your pet was originally registered with HomeSafeID, you’ll need to manually transfer their registration to ensure they remain traceable.

Find your pet’s microchip number on your pet’s paperwork or ask your vet or local shelter to scan your pet.

Use www.petaddress.com.au to check your pet’s microchip registry.

If it shows HomeSafeID, re-register your pet’s microchip with Central Animal Records (CAR).

Visit CAR’s website and follow the instructions to update your contact information.

Keep a record of your pet’s microchip number and new registry name. Check your details annually – just like checking your smoke alarm!
