Find the number
It is on the implant paperwork, on the rabies certificate if the vet recorded it, or your vet or a shelter can scan for it in seconds. Log it in PawPass on the pet’s microchip tab.
Find the registry
Chips are registered with a registry, not with the vet. Look the number up in a universal lookup tool to see which registry holds it. If none does, register it yourself with the manufacturer’s registry or any of the major ones.
The checklist
- The chip is registered, not just implanted.
- It is registered to you, not the breeder, shelter or previous owner.
- Your phone number and email are current.
- There is a second contact who would answer if you did not.
- The address is your current one.
When you move or change numbers
Update the registry the same week. It is the step most people miss, and the one that decides whether a found pet comes home.
Travel and renting
Some countries require a microchip before the rabies vaccination for it to count, and some landlords ask for the number on the pet addendum. Keep it with the record so it is on the page you already share.

Rules and guidelines change, and businesses set their own policies. Confirm with your vet and with whoever is asking.
