Register your pet for life

Cat and dog owners in NSW are legally required to microchip and register their pets. Kittens and puppies must be microchipped before they are 12 weeks old or before being sold or given away. They must then be registered before they are 6 months old.

All cats and dogs over 12 weeks old must also wear an identification disc that is engraved with their name and their owner’s contact number, which is attached to their collar when outside their home.


If your pet goes astray and is taken to a vet, pound or shelter by a City of Sydney ranger or a member of the community, we can contact you quickly.

The microchip is only about the size of a grain of rice and needs to be inserted by an accredited microchip implanter (between the animal’s shoulder blade). Rest assured the procedure is almost painless and your pet won’t be harmed.

Once your pet is microchipped, you’ll be asked to fill in a standard form. The implanter will then enter the information into the NSW Companion Animal Register or send it to us to be entered. You will be given the pink copy for your records. Once the information has been entered into the database you should be sent a certificate of identification.


To register your pet, bring your pet’s identification certificate and any other relevant documents to a Neighbourhood Service Centre, or post photocopies. We’ll link your contact details with your pet’s microchip number, which is held securely and confidentially on a state-wide database. A one-off fee applies.
