The chip is the document; the database registration is what actually brings the dog back. The difference is critical: thousands of chipped but unregistered dogs fail to reach their owners each year simply because the number is linked to nothing.
Dog: Chip and Database Registration
The microchip is mandatory in many states, and database registration (Tasso, Findefix) is free and finds a lost dog. Plus the EU pet passport for travel.

I registered the chip with Tasso the day I picked up the puppy — 10 minutes online, free. A year later a neighbour found the escaped dog in an hour thanks to exactly that record.

Planning EU travel? Get the pet passport with a current rabies vaccination a month ahead: the shot must mature 21 days before entering another EU country.
FREQUENTLY ASKED QUESTIONS
Are the chip and the tax tag the same? ▾
No: the tax tag is about city tax, the chip about nationwide and EU identification. Both needed, they do not replace each other.
The dog is chipped but not in Tasso — is that not enough? ▾
No: a chip without database registration is useless when found — the scanner shows the number but not your contacts. Registration is free and done online in 10 minutes.
Moved or changed number — must I update? ▾
Absolutely: outdated Tasso contacts are the main reason chipped dogs are not returned. Update the data at every move.
