The Chip Stays Put, the Registration Moves
A microchip itself never needs replacing when a cat is adopted. The tiny chip under her skin keeps its number for life; what changes is the registry record attached to that number, which still names the rescue, breeder, or previous owner until you transfer it. Until that transfer is done, anyone who scans her, from a vet to a shelter to a finder, will be directed to the old contact details, which is why this job belongs in the first days of adoption rather than on a someday list.
Start by getting two things from whoever you adopted her from: the chip number itself, usually on her adoption paperwork or vaccination card, and the name of the database company holding the registration. Reputable rescues often begin the transfer for you or hand over a transfer form, so ask directly what they have already done before assuming nothing has been started.
Making the Transfer With the Registry
Contact the registry and follow its transfer process, which typically involves confirming the previous keeper's details or a transfer code, then registering your own name, address, and at least one phone number you answer reliably. Some registries charge a small administration fee or offer upgraded accounts, but the essential task is simple: the record for her number must end up pointing at you. Give an email address you check often as well, since registries increasingly send scan alerts and confirmation messages electronically.
When the registry confirms the change, save that confirmation with her adoption papers and check the record reads exactly as you gave it, digit by digit on the phone number especially. A single wrong digit survives unnoticed for years and only reveals itself on the worst possible day, so this two-minute check is the most valuable part of the whole process.
Verify the Number at Her First Vet Visit
Ask your vet or nurse to scan her during her first check after adoption and read the number back to you. Match it against the paperwork and the registry confirmation. Occasionally the number on a handed-over card belongs to a previous pet or was transcribed with two digits swapped, and catching that now, while the rescue still has its records open and remembers her, is far easier than untangling it later.
That visit is also the moment to confirm the registry has your vet's details recorded if it offers a secondary contact field. A clinic that knows her is an excellent backup contact because its number is answered during working hours even when your phone is off, lost, or out of signal.
Keep the Record Alive as Life Changes
A transferred chip only stays useful if the record keeps up with you, so treat any change of phone number, address, or email as a prompt to update the registry the same week. If she is ever rehomed again, pass the chip details and registry name to the new owner and encourage them to transfer promptly, just as you did, so the chain of contact never breaks.
With the registration settled in your name, her KinsLe Pet Pass gives you her verified ID card to show anywhere, carrying her identity and your contact details in a form that backs up the chip record whenever paperwork is asked for.
