PetScanner is built to support both pet keepers and professionals, including vets, rescues and local authorities, we combine registration and scanning in one system. This helps reduce delays in identifying pets and increases the likelihood of a safe and quick reunion. As a DEFRA-compliant microchip database, we allow keepers to securely register their pet’s microchip details for a small fee. Registration includes unlimited contact detail updates for life and optional subscription benefits giving you exclusive perks on top of your DEFRA registration. Alongside registration, the PetScanner app pairs with the PetScanner smart microchip scanner to provide fast and effective identification of microchipped animals. The scanner reads FDX-B (15-digit) microchips in dogs, cats and other animals, instantly displaying the unique microchip number within the app. Please note, a PetScanner smart microchip scanner is required to scan your pet – you cannot scan the microchip with your smartphone alone. When a pet is scanned, PetScanner guides you through the next steps based on the microchip’s registration status. If the microchip is registered with PetScanner, the keeper’s contact details will be displayed, making it easy to get in touch. If the microchip is registered with another database, PetScanner will identify the relevant database and provide the appropriate contact information. If no registration is found, the chip number is still shown, allowing the pet to be identified and registered if needed.
