When should you update a cat’s microchip details?
Update a cat's microchip record after every change in address, phone, email, keeper or emergency contact. The chip helps only when the correct registry can reach someone.

✓ A microchip only helps reunification when the registry can reach the current keeper
✓ Check the registered database after every contact change and ask the clinic to scan the chip at routine visits.
✓ A microchip does not provide GPS tracking; report a missing cat promptly through local channels.
A microchip only helps reunification when the registry can reach the current keeper. Moving, changing phone number or transferring ownership can make old records useless.
Know when to update
Check the record after moving, changing telephone number or email, transferring ownership, adopting, changing emergency contacts or discovering that older details are incomplete.
Verify the chip and registry
Ask a veterinary clinic to scan the chip at a routine visit and note the full number. Confirm which authorised database holds the record, then update details directly with that registry.
Do not confuse identification with tracking
A standard microchip has no battery and does not transmit a live location. It identifies the cat when scanned. A visible collar tag, when safely tolerated, can provide a faster second contact route.
Prepare for a missing-cat emergency
Keep the chip number, registry contact and a current clear photo accessible. Report the cat missing to the registry promptly and contact local clinics, shelters and relevant search services.
Common mistakes to avoid
Do not assume a breeder, rescue or previous keeper completed the transfer, and never post the full chip number publicly. If a scanner cannot find the chip, ask the veterinary team about repeat scanning and next steps.

Questions cat people ask
How do I update my cat's microchip details?+
Find the registry linked to the chip number and follow its official update process. A veterinarian or scanner can help identify the registry if records are missing.
Do microchips track a cat's location?+
No. Standard pet microchips are passive identification devices read by a scanner; they are not GPS trackers.
