If they wander off, you find out first.
Anyone who scans your pet's tag can notify you by email instantly, no contact details shared either way. WhosPet is invite-only for now while we test it with a small group.
Not just a boring tag
Personalised with their name
Every tag is printed with your pet's name — pick it when you claim your tag.
A range of designs
We're starting with one simple 3D-printed shape and building out more styles from there.

Vital info, right when it's needed
Allergies, medications, and your vet's contact details sit on your pet's profile and show up the moment anyone taps or scans the tag — whether or not your pet is marked lost. A stranger who finds a diabetic cat, or an old dog on medication, doesn't have to guess.
If it actually happens, say more
One tap on your dashboard marks a pet as lost. The scan page switches to an urgent alert and shows finders whichever contact details you pick: phone, email, WhatsApp, or address. You can also leave those details on the public tag page all the time, from the pet profile.
Mark them found again any time to turn the alert back off. Contact details stay visible only if you've chosen to show them. You can also print a poster with a scannable QR code straight from your dashboard.

How it works
Tap or scan
A finder taps the tag with any modern phone, or points their camera at the QR code on the back — no app required. If neither works, the tag's code and website are printed on it too, so they can just type it in.
Finder says hi
They see your pet's profile and can leave a message and their location, if they choose to share it.
You get notified
An email lands in your inbox within seconds, with everything the finder shared.
Why not a microchip or an old-school tag?
Both have real gaps — WhosPet is built around exactly those.
Microchips need special equipment
Only a vet or shelter can read a chip, so whoever finds your pet can't do anything until someone takes them in. A tag works instantly, with any phone.
Old tags broadcast your details
A traditional tag exposes your phone number or home address to anyone who picks it up — permanently, even after you've moved. WhosPet relays messages without sharing either.
Always up to date
Changed your number or want a new photo? Update the profile online — no re-engraving, no new tag.
Ready when they need it
WhosPet is invite-only for now. If you've been given a tag, set it up in a minute.
