Microchipping is a safe and permanent way to identify your pet, helping to reunite lost animals with their owners. A tiny microchip, implanted just under the skin, contains a unique number linked to the NSW Pet Registry, where the owner’s contact details are recorded. If your pet ever goes missing, this information allows vets, councils and shelters to quickly identify and return them home.
Who is responsible for microchipping?
In NSW, the person selling or rehoming a pet is legally required to ensure it is microchipped. This includes:
✔️ Registered breeders
✔️ Animal rescue or rehoming organisations
✔️ Individuals giving away pets, including accidental litters
Before purchasing or adopting a pet, you should be provided with its microchip number, which you can verify using the NSW Pet Registry buyer’s search.
If you take ownership of a pet that hasn’t been microchipped, your local vet can assist with the procedure.
When should a pet be microchipped?
By law, all dogs and cats must be microchipped before being sold or rehomed, or by 12 weeks of age—whichever comes first. The details provided at the time of microchipping must be recorded by a vet or authorised identifier. These details can only be updated through a formal transfer of ownership, which is the responsibility of the breeder or previous owner.
