Pet Exchange Register FAQs

The Pet Exchange Register (PER) is an online database where individuals, organisations and businesses can register for a source number. It promotes responsible pet breeding and improves the traceability of dogs and cats being sold in Victoria.

All advertisements to sell, rehome or give away a dog or cat must display each animal’s microchip number and a unique source number from the PER.

A source number is required when implanting a microchip into a dog or cat born after 1 July 2020

  • identifies an individual, breeder, business or organisation
  • is generated once an individual enrols on the PER
