Pet Microchip FAQs

An RFID (Radio-Frequency Identification) pet microchip is a tiny passive electronic transponder about the size of a rice grain. The chip is implanted painlessly by a veterinarian under the pet’s skin and requires no battery since it’s only activated when scanned. When a scanner passes over the chip, it uses radio waves to power up the chip momentarily, which then transmits a unique identification number back to the scanner.

A microchip is NOT a GPS tracker – it simply stores a permanent ID number that links to owner information in a registry database.

When you have your pet microchipped, your vet should confirm whether they have registered the chip for you. If not, you will need to do this as soon as you leave the vet. It is crucial every pet’s microchip is registered with the owner’s contact information.

Click here to register a microchip with PetLink or enter the microchip number in the field above to check your chip is registered and your details are up to date.

Without registering your pet, the microchip won’t have your contact details associated with it, which prevents you being reunited with your pet if it ever goes missing. Register your chip with PetLink today:

Each microchip is assigned a unique identification number. A veterinarian or animal shelter professional is able to scan the chip to display the ID number, which is then used to search a database. The database will show the pet’s information as well as their owner’s information – which is why it is crucial as a responsible pet parent to always keep your contact details updated in your PetLink account.
