The chip is your pet's passport number
Every document in a Taiwan pet import — the rabies certificate, the FAVN lab report, the APHIA permit, the export health certificate — is anchored to one 15-digit number. At Taoyuan airport, the inspection starts with a scanner: if the number under the skin doesn't match the number on the file, the file might as well belong to a different animal. That's why the microchip is step zero of the import checklist, before any vaccine, test or form.
What "ISO chip" actually means
Taiwan — like the EU, Japan and most of the world — works with microchips conforming to ISO 11784/11785: a 15-digit number transmitted at 134.2 kHz. The complication is regional: some chips, common in North America over the years, use other frequencies (125 or 128 kHz) and 9- or 10-digit formats that a standard ISO scanner may not read at all.
| Chip type | Format | Taiwan-bound verdict |
|---|---|---|
| ISO 11784/11785 | 15 digits, 134.2 kHz | Correct — proceed |
| Non-ISO (125/128 kHz) | 9–10 digits | Risky — the arrival scanner may not read it; act before vaccination |
| No chip yet | — | Implant an ISO chip first, then start the vaccine and titer sequence |
The order rule that catches people
Regulators only trust identification that existed when the medical event happened. A rabies vaccine given before the chip was implanted can't be proven to belong to your pet, so on paper it doesn't exist — and neither does the titer test that depended on it. The sequence is always: chip → scan and record → vaccinate → titer. Break it, and the fix is re-vaccinating and re-testing on the far side of a restarted calendar.
What to do in each situation
- Pet already has an ISO chip: verify it scans, then make sure every new document copies the number digit-for-digit. Transposed digits on a certificate are a classic arrival-day failure.
- Pet has a non-ISO chip: the standard fix is implanting an ISO chip alongside the old one (they don't interfere) and restarting the vaccine/titer sequence against the new number, with both chips noted on the paperwork. Alternatively, some owners travel with their own ISO-compatible scanner for the old chip — workable, but fragile; ask before relying on it.
- No chip: easiest case — implant ISO, and the whole file is born clean.
- Registration: update the chip registry to your details, with a phone number that will work in Taiwan. The chip is also your reunion tool if anything ever goes wrong in transit — a chip pointing at a disconnected number protects no one.
Thirty seconds of prevention
Next vet visit, ask for a scan and photograph the scanner display. That photo — number, date, your pet in frame — is the cheapest insurance in pet relocation. And if you're not sure what your pet's chip situation means for a Taiwan move, send us the details; auditing the chip-vaccine-titer sequence is the first thing we do on every file.
