Animal Microchipping

Pet microchipping

Being able to identify your pet is very important in ensuring the quick and safe return to you if it gets lost. When Council collects a pet that is lost they make the best effort to return it straight to back to the owner rather than taking it the impound facility and microchips aid this process.

Microchips are implanted under you pet's skin. They are encoded with an identification number which can be read by scanners. If your pet loses its collar and tag, council's Rangers will still be able to find out where it comes from and contact you provided your details are kept up to date with the microcrochip database.

All cats or dogs registered with a Council for the first time must be microchipped prior to registration.


Source numbers

As of 1 July 2020, new state laws came into effect around the details recorded on microchip records. All dogs and cats born and microchipped after 1 July 2020 must have a source number from the Pet Exchange Register listed with the microchip details.

What is a source number?

A source number:

  • identifies an individual, breeder, business or organisation

  • is generated once an individual enrols on the Pet Exchange Register

  • is automatically allocated to domestic animal businesses and foster carers following registration with Council.

Why do I need a source number?

The source number will identifiy where the animal was bred and can help prevent illegal breeding businesses, monitor animal welfare standards and trace hereditary medical conditions in licenced breeding establishments.

If you are selling or giving away a cat or dog you will also need to include the source number in the advertisement. It is illegal to advertise or to publish an advertisement without a source number. Penalties apply. 

Can I get my pet microchipped without a source number?

No. Licenced implanters can face penalties for failing to include the source number with the prescribed information recorded with the microchip.

How do I get a source number?

You can apply for a source number at Pet Exchange Register or call Animal Welfare Victoria on 136 186.

More information can be found at Central Animal Records or at Animal Welfare Victoria

How to get your pet microchipped


Veterinary clinics are able to implant microchips.

When the identity chip is implanted, you will have a unique ID number assigned to you and your ownership details will be maintained on the microchip company’s database.

If you change your address, your phone number, or take ownership of an animal from a previous owner, make sure you contact the company your details are recorded with immediately to have your pet's information updated. If you are not sure which database your details are listed with, visit:

and enter your pet’s microchip number. This will tell you what database you need to contact to update your information. 

Some information can be updated online on the microchip company’s website.
