New puppy basics
How do I choose microchip registration details for my new puppy?
Last updated 23 September 2026 · How we write and check this
Short answer
Confirm whether your puppy is already microchipped by the breeder or shelter, then register or update your own current contact details, including phone number and address, on the relevant database as soon as possible, since an outdated or unregistered chip is of little use if the puppy is ever lost.
Check what you have inherited first
Most puppies from breeders or shelters already carry a microchip, but it is commonly still registered to the breeder or organization rather than you, so updating ownership details promptly is an important early task rather than something to leave for later.
Keep the details current going forward
A phone number or address change after registration is easy to overlook, but an outdated contact detail defeats the purpose of the chip entirely if your puppy is ever found by someone else. Set a reminder to review the registration whenever your details change.
Practical steps for getting this right
Ask your vet at the first visit to scan the chip and confirm the number matches what is on any paperwork you were given, since a mismatch or an unreadable chip is far easier to sort out early than after months have passed without anyone checking.
Register a second contact, a family member or close friend, alongside your own details where the database allows it, since a missed call during a busy workday is exactly the kind of gap that can delay a reunion if your puppy goes missing and is found quickly by someone nearby.
Keep a note of which specific database your puppy's chip is registered on, since several different registries operate in most countries, and confusion between them is a common reason a found puppy takes longer than necessary to be reunited with its owner. A five minute check now is a small price for that peace of mind later.
Key takeaways
- Check whether your puppy already has a microchip and confirm who it is currently registered to.
- Update ownership and contact details on the relevant database as soon as possible after collection.
- Review and update the registration again any time your phone number or address changes.
