What is a microchip?

A microchip is a small electronic chip, the size of a grain of rice, that is implanted under the skin between the shoulder blades. It contains a unique number that can be read by a scanner. Your pet's microchip is not a GPS tracker.

How does it work?

When using a scanner, we can read the unique number that identifies your pet. We can then connect it to your contact information, which is kept in a secure database. If your pet goes missing or is stolen, having them chipped offers the best chance of them being returned to you.

Make sure your pet is registered on a government-approved database. These are:

AnimalData

Animal Microchips

Animal Tracker

Chipworks

HomeAgain

Identibase

Lost Paws

MicroChip Central

MicroDogID

My Animal Trace

MyPet

National Veterinary Data Service

Pet Chip Register

Petlog

We Trace Pets

Please note that some rules and databased approved companies are different if you’re in Scotland, Wales or Northern Ireland.

The government can fine you up to £500 if your pet is registered on a database that is not on their list.

When to get your cat microchipped

Your cat must have a microchip, by law in England, by the time it's 20 weeks old. Microchipping is quick and simple to do, just like an injection.

Dogsmust also be microchipped by law. The microchip must be implanted in your dog by the time it's 8 weeks old or over.

Where to get your pet microchipped

Microchipping your pet can be done by your vet or the local council. They might charge a fee. Cat rescue organisations may also be able to help with this.

Keep your details up to date

It is your responsibility to keep your pet’s microchip information up to date. Contact the database company if you need this to be updated, for example, if you move home.

Occasionally, your vet will do this for you, but there is usually a charge for this service.

What if you're getting a pet that already has a microchip?

Find out where your pet is registered. You can check which database your pet is registered in here. If you do not have the microchip number, you can ask a vet, a dog warden or a rescue centre to scan your pet.

Getting a cat

You should ask for proof a microchip has been fitted before getting a dog or cat.

You can ask to see any of the following as proof:

  • microchip certificate

  • vet records

  • pet passport

  • pet insurance papers
