Blog: What is Microchipping? Your Pet’s Permanent ID for Life

Your pet means the world to you. A microchip is one of the simplest, most reliable ways to make sure they can always find their way back to you – for life.

What is a microchip?

A microchip is a tiny device, roughly the size of a grain of rice, that is implanted just beneath your pet’s skin – typically between the shoulder blades. It’s a quick procedure, similar to a routine injection and most pets barely notice it.

Each microchip contains a unique identification number. That number is permanently linked to your contact details in the PetLink database, so if your pet ever goes missing, anyone who finds them – a vet, shelter, or animal control officer – can scan the chip and trace them back to you.

No batteries. No signals. No expiry date. Just permanent, lifelong protection.

How does it work?

1. Your pet is microchipped by a vet or trained professional.
2. You, your vet or shelter register your chip on PetLink.net, linking your pet’s unique ID number to your contact details.
3. If your pet goes missing, a vet, shelter, or rescue organisation scans the chip with a standard reader.
4. They contact you using the details stored on the PetLink database, and your pet comes home.

It really is that straightforward – but only if your details are up to date. That’s why it’s so important to log in to your PetLink account and check your information regularly.

Why is microchipping so important?

Unlike a collar or tag, a microchip cannot fall off, be removed or wear out. It’s a permanent form of identification that stays with your pet throughout their entire life – making it one of the most trusted and widely used forms of pet ID in the world.

In many countries and states, microchipping pets is a legal requirement. But regardless of the rules where you live, it’s simply one of the best things you can do for your pet.

Good to know: Microchipping is just the first step

A microchip is essential – but it only works once your pet has been found and scanned. Think of it as your pet’s safety net. For even greater peace of mind, PetLink offers a complete range of pet safety products that work together:

PetLinkGPS Tracker

While a microchip helps reunite you after your pet is found, a GPS tracker puts you in control to help you find them before it’s too late. The PetLinkGPS tracker lets you track your pet’s location in real time, straight from your smartphone – so you can act fast the moment they wander.

Personalized ID Collars & Tags

A microchip requires a scanner to read. But a personalised ID collar or tag means that any member of the public who finds your pet can contact you immediately – no scanner needed. It’s an instant, visible way for a good samaritan to get your pet home quickly.

The complete pet safety combination

Each pet safety product plays a unique role:

• Microchip Permanent lifetime ID – can’t be lost or removed
• PetLinkGPS Tracker – Real-time location tracking – find your pet fast
• ID Collar & Tag – Instant visible ID – anyone can contact you

Together, they create the strongest possible safety net for your precious family member.
