Updating a Pet's Microchip Details

Ensuring a pet's microchip details are current is a critical part of responsible pet ownership, particularly when moving home. A microchip acts as a permanent identification, linking a pet to its owner through a registered database. Without up-to-date information, the chip's purpose is undermined, making reunification difficult if a pet becomes lost.

Step 1: Identify the Microchip Database

The first step involves identifying which of the various UK microchip databases holds the pet's details. Unlike some other countries, the UK operates multiple independent databases. Common databases include Petlog, Animalcare, Smartchip, and MicroChip Central. If the database is unknown, the easiest way to find out is to enter the microchip number into an online microchip lookup tool. A veterinary practice can also scan the chip and provide this information.

Step 2: Locate the Microchip Number

The pet's unique 15-digit microchip number can typically be found on documents received when the pet was chipped, such as veterinary records, vaccination cards, or pet insurance paperwork. If these documents are unavailable, a vet can scan the pet and provide the number.

Step 3: Contact the Database Provider

Once the database and microchip number are identified, contact the specific database provider directly. Most databases offer online portals for owners to manage their details, or provide a customer service telephone number for assistance. It is crucial to go directly to the registered database, as information cannot be updated via a different provider.

Step 4: Update Personal and Address Details

Provide the new address, updated telephone numbers, and any new email addresses. It is advisable to update all contact points to ensure multiple avenues for contact should the pet go missing. Some databases may charge a small administration fee for address changes, particularly if upgrading to a premium service that allows unlimited updates.

Step 5: Verify and Confirm the Update

After submitting the new details, ensure a confirmation is received from the database provider. This might be an email, a letter, or an update visible in an online account. A good practice is to periodically check the details are still correct, especially after a significant life event such as a house move. Consider who else needs a new address, such as the pet's insurance company or local council.

Important Considerations for Pet Owners

  • Moving Home: Updating the microchip before moving house is essential. Pets can sometimes wander during the upheaval of a move, and current contact information significantly increases the chances of a safe return. More guidance on how to help a pet settle in a new home is available.
  • Ownership Changes: If a pet changes ownership, the previous owner must initiate the transfer of microchip details to the new owner through the database. This ensures legal ownership is correctly recorded.
  • Deceased Pets: Should a pet pass away, it is also important to notify the microchip database to update their records.
  • Mandatory Microchipping: In the UK, it is a legal requirement for all dogs over 8 weeks old to be microchipped and for their details to be kept up to date. From June 2024, similar rules will apply to cats. Non-compliance can result in a fine.
