Chip check

Find out who holds a pet’s microchip record, and what to say when you call.

What’s happening?

1. Find the chip number on your pet’s papers, or get it from the clinic or shelter that scanned the pet.

2. Enter it in AAHA’s free microchip lookup. AAHA lists any companies that hold the chip, most recently updated first.

3. Contact the first company listed. If your pet is missing, ask them to mark your pet missing and confirm your phone and email. If you found a pet, they’ll usually contact the owner. If a found pet’s chip isn’t found, ask the company that made it for a “trackback”.

Sources and notes

Chip check runs on your device. We don’t save or send the chip number unless you choose to save it to your own pet, and reloading the page clears it.

AAHA’s lookup is for adults. If you’re under 18, a vet clinic or shelter can look it up with you.

Hints come from public sources. A chip’s first digits name who probably made it, not where it’s registered now. AAHA’s lookup is the reliable way to see that. Last checked 2026-10-05.
