If you’ve lost or found a pet, Fi Nano’s secure messaging system helps reunite them safely - without sharing any personal contact information. Anyone can use this feature, even without a Fi Profile.
Every Fi Nano microchip is also searchable through the AAHA Universal Pet Microchip Lookup Tool and links directly to our registry, making it easier and faster to bring pets home.

If You Lost Your Pet
When your pet’s microchip is scanned, the finder can reach out through Fi’s secure messaging system without accessing your personal information. Their message will be delivered to the email and as a text to the phone number linked to your Fi Nano registration.
Note: Fi Nano does not currently have a feature to flag microchips as "lost" in our system.
Make sure you can be reached
