Report a missing cat in a set order, because each step makes the next one work: find the chip number from the vet paperwork or read back from the cat's own record, contact the registry it is registered with, have the record flagged as lost, confirm the contact details on the record are current while you are on the call, and ask that your details can be shared with a finder or vet who scans her. A flagged record changes what happens at the worst moment: her chip gets scanned at a practice or rescue, the number is read, and the record it calls up says lost, with your details ready to share. Do those steps in the first hours, while the search is also running, not after it.
Find the Number First
Everything starts with the chip number itself, and there are two reliable places to get it. The first is her paperwork: the vet documents, adoption papers, or registration confirmation from when the chip was implanted or last updated. The second is her own saved record: the number stored with her profile and vet details, read back from the record rather than remembered, because one wrong digit makes the registry search fail silently. A scan, whether at implantation or at a check, yields the chip number only; the details live on the record that number calls up, which is why reading the saved record back, digit by digit, is the careful way to confirm you are working with the right number. Keep the full number off public posts.
Contact the Registry and Flag the Record
With the number confirmed, contact the registry it is registered with, by phone or through its lost pet route, and have the record flagged as lost. If you are not sure which registry holds her chip, the veterinarian who implanted it, or any practice that has scanned her, can usually tell you which registry a number belongs to. Flagging is the step that turns a stored record into an active alert on her file, so the lost status is what anyone checking the number sees first. Ask the registry to confirm the flag is live before you end the call, and note the name of the person who confirmed it and the entry label for the call, such as Monday evening call, in your own notes.
Check Every Detail While You Are on the Call
A lost flag on a record with an old phone number is a doorbell in an empty house, so confirm the contact details on the record are current while you are on the call: the phone number a finder would be given, a second contact if the registry allows one, and the address the record carries. Then ask directly that your details can be shared with a finder or vet who scans her, because some records carry sharing choices made years ago, and a finder who is told the owner cannot be contacted is a reunion delayed by paperwork.
Tell the Vets and Rescues, and Flag Her QR Profile Too
Registries are one net; local knowledge is another. Tell the local vets and rescues the same chip number, in full, directly to them, because a found cat is often scanned at the nearest practice, and a practice that already holds her number and her lost status can match her on the spot. Her collar carries a second route to the same end: her own unique QR profile, through the Verified QR ID Pet Profiles, can carry the same lost flag story, so a finder without a scanner can still reach her profile and see that she is missing. When she comes home, update both flags the same day, registry and profile, so a future scan does not raise a false alarm. Alongside registry calls, your Verified QR ID Pet Profiles entry within KinsLe shows the lost status too, so anyone meeting her can open the profile and contact you through it.
