Yes, the order matters, and it runs by who would need the record in an emergency: update the chip registry first, then the vet's file, then the city license, checking the collar tag separately afterwards. Moving week raises the exact risk the registry exists for. Boxes, open doors, visitors carrying furniture, and a dog unsettled in an unfamiliar street all make an escape more likely, while the new neighbourhood holds nobody who recognises her. If she is found and scanned in those first days, the registry record is the route home.
First: The Chip Registry
Understand what you are updating. The chip itself, sitting under the skin, carries only its number; it does not store your address and it is not edited by the move. The details live in the registry record linked to that number, and that record is what you change. Contact the registry the chip was enrolled with, by its website or phone line, and update your mobile number first, then a second contact who does not live at the new address, then the new home address itself. A mobile that travels with you matters more than a landline tied to either house. When you finish, do not assume the change landed. Ask for confirmation, or log back in and read the record as a stranger would: the number, the phone, the address, exactly as a finder would be given them. If an old number still shows, fix it before you move on to anything else, because a half-saved update looks identical to a completed one until the day it is needed.
Second: The Vet's File
With the registry current, update the practice that treats her. The vet's file needs the new address and your current phone so invoices, reminders, test results, and urgent calls reach the right house, and so her clinical record matches the dog presented at the desk. If the move takes you to a new practice, register there promptly and ask for her history to be transferred, rather than waiting for the first illness to force a paper chase between two clinics. Tell the practice the chip number on file too, and ask them to check it against the number their scanner reads at her next visit, so the file, the chip, and the registry all describe the same dog.
Third: The City License, and the Tag as Its Own Layer
Licensing comes last because it reunites nobody: it is a local administrative record, often tied to your address and to proof of rabies vaccination, and it should still be done promptly under whatever local deadline applies. Missing it risks a fine or a lapsed registration, not a lost dog staying lost, which is why it queues behind the two records that protect her directly. Treat the collar tag as a separate physical layer rather than part of any of the three files. If the tag shows your mobile number and that number has not changed, it still works untouched. If the move came with a new phone number, or the tag carries the old address, replace the tag, because a tag is read by a neighbour with no scanner at all. Registry, vet record, license, and tag fail in different ways, and a move is the moment to check each layer on its own terms.
A Simple Move-Week Sequence
Before the vans arrive, do the registry update and read it back. During the first week in the new house, update the vet's file and order any replacement tag. Within the local window your area allows, complete the license change and file the confirmations together: registry read-back, vet details, license receipt, and a note of the tag wording. KinsLe gives those confirmations a permanent home within its Pet Passport section, alongside vaccination history, ready whenever another address change begins.
