A submitted form feels like a finished job: you typed the new address, pressed save, and saw a thank-you message. None of that proves the change survived. Requests fail quietly — a mismatched chip number, an account held with a different registry, a form that was received but never processed. The only confirmation worth having is the saved record itself, read back after the change, showing your new details in place of the old ones.
Submitted Is Not Saved: The Read-Back Test
Run the check in this order. First, submit the address change through the registry that holds your cat's record, keeping any reference the system gives you. Second, log out completely, then log back in afresh — a fresh login forces the site to show the stored record rather than the form you just filled. Third, open the record and read every field: the address, each phone number, and any secondary contact, exactly as displayed. If you confirm by phone instead, ask the agent to read the saved address and numbers back to you word for word, and ask whether a written confirmation or reference exists for the change. A fresh login showing the new address is proof; a submission receipt is only evidence that you asked.
What the Chip, Scanner and Registry Each Do
Owners often picture the address living inside the chip. It does not. The chip implanted under the skin holds one thing only: a unique number, which it reveals when a scanner passes over it. The chip carries no address, no phone number and no tracking capability. The registry is the database that links that number to your contact details, and it is the registry — not the chip, and not the scanner — where an address change must be saved. This is why the read-back test targets the registry record, and why a vet scanning your cat can only ever confirm the number, then use it to look the record up. Knowing which layer holds what stops owners updating the wrong place and relaxing.
The Separate QR Layer
A collar QR tag works differently, and the difference matters here. Scanning the tag opens your cat's profile — a page you control, which you can edit instantly at any hour, showing the contact details and notes you choose to publish. That speed is its strength for a finder standing in the street with your cat in their arms. But the QR profile and the registry record are separate layers maintained in separate places: editing the profile does not write anything to the registry, and updating the registry does not refresh the profile. After a house move, both need the new address, checked separately, because a finder may reach you through either route — and a vet or shelter who scans the chip will follow the registry route only.
When the Read-Back Shows the Old Address
If a fresh login still displays the old address, work through the causes calmly. The request may still be processing, so note the reference and repeat the read-back after a short interval. You may hold accounts with more than one registry — cats are sometimes registered twice, by a breeder, rescue or vet, and the duplicate record under the old address survives untouched unless you update that registry too. Or the chip number on your paperwork may not match the number the registry holds, which a quick scan at your vet can settle. Keep proof of every submission, re-submit where needed, and re-check until the saved record itself shows the change. Keeping both layers current matters, and KinsLe separates them clearly: Verified QR ID Pet Profiles for instant finder contact, while the registry alone holds the chip record.
