What microchip paperwork should go home with a puppy?
Send the microchip number, the manufacturer or database it is registered with, and a plain explanation of how the registration is transferred into the new owner’s name — including anything they must do themselves and by when. The number alone is not enough: a chip registered to a breeder who has moved house is a chip that leads nowhere.
Three things, not one
The number, the database, and the transfer. Owners routinely receive the first and assume it is the whole job, which is how chips end up scanning correctly at a vet’s desk and resolving to a breeder’s old phone number.
The number is usually fifteen digits and it must be exactly right — a single transposed digit produces a number that scans to nothing. Copy it from the chip’s own peel-off label rather than from memory or from a handwritten note, and check it against the label again before it is printed.
Say which database the chip is registered with, because there are several and the new owner cannot tell from the number. And say what the transfer requires of them: whether you have already initiated it, what they will receive, what they must confirm, and roughly when they should chase it if nothing arrives.
Why a wallet card is worth more than another page
The moment the microchip number matters is the moment a dog is missing, and nobody is going to be leafing through an A4 folder. The number needs to be in a wallet, in a phone, or stuck inside a kitchen cupboard.
So the microchip page in a PuppyGoHomePacket packet carries a wallet-sized card on a cut line: the puppy’s name, the chip number, and your phone number as you typed it. Cut it out and it lives in a wallet.
The card also carries a QR code that saves your contact details to the new owner’s phone as a contact card. It is generated on your own machine while the packet is being made — it is not a hosted link, nothing is looked up when it is scanned, and it will still work in five years when this website may not exist. The one thing to check: put your phone number on its own line in your contact block, because that is what the code reads.
What the packet will not do
It will not register a chip, transfer a keepership, or talk to a microchip database. In the UK the keepership transfer is a legal step at handover, and the UK puppy pack page says who has to do what. Those happen on the database’s own site, by you and by the new owner, and the packet’s job is to say clearly what has been done and what has not.
It also will not invent the wording for you. The note about registration and transfer is a field you type, because the correct wording depends on which database you use and which country you are in, and a generic paragraph would be wrong for most readers in a way that is hard to notice.

Make this packet without retyping it eight times
PuppyGoHomePacket is a puppy go home packet maker for breeders: you enter the litter once — sire, dam, pedigree, weights, vaccinations, feeding plan — and it generates a finished packet for every puppy, a ZIP of the litter, and your own litter record. The editor is free and there is no account: build the whole thing and preview every page with your own dogs in it before deciding anything.
