TLDR: If your pet has two compliant microchips, both numbers must be recorded on all lab reports, health certificates, and import applications. Both must be scanned at every single vet visit. A single incorrect digit on any document will halt the import. Australia also explicitly refuses microchips that start with '999' because they are not unique.
Some pets end up with two microchips. This can happen if a chip was implanted overseas and another was added later, or if a previous chip stopped scanning and a new one was placed. If your pet has two compliant microchips, Australia has specific rules for how they must be handled.
Australia requires an ISO-compliant microchip (10 or 15 digit) to be implanted and scanned before any tests, treatments, or vaccines are administered.
The exact microchip number must appear on every lab report, vaccination record, and health certificate. A single incorrect digit will halt the import.
If your pet has two compliant microchips:
Both numbers must be recorded on all lab reports, health certificates, and import applications
Both must be scanned at every single vet visit
This is not optional. If one microchip number is missing from any document, or if only one chip is scanned at a vet visit, the documentation will be incomplete and the import can be halted.
Australia explicitly refuses microchips that start with '999' because they are not unique.
