Change of address and ownership for pets

When you purchase a companion animal or have been given a companion animal, ensure that the previous owner or breeder sends the local council a signed and completed Change of Owner/Details C3A Form

If you sell or give away a companion animal, it is your responsibility as the 'old owner' to update the new owner's details on the Companion Animals Register at your local council, otherwise penalties may apply.

Selling or giving away a cat or dog? The rules have changed.

From 1 July 2019, people advertising kittens, cats, puppies or dogs for sale or to give away in NSW will need to include an identification number in advertisements. The identification number can be either:

  • a microchip number
  • a breeder identification number, OR
  • a rehoming organisation number.

The rules will apply to all advertisements, including those in newspapers, local posters, community notice boards and all forms of online advertising, including public advertisements on websites such as the Trading Post, Gumtree and social media sites.

For more information visit the Department of Primary Industries website.



Change of address or contact details


If your address or phone number changes you can lodge a Companion Animal Register Enquiry request online with Council. Our Officers can update these details on your pet's microchip.
