Passport? Good.

Compared across countries

What number do you call in an emergency?

For a trip that crosses borders — the same question, answered country by country.

The pattern

119 is the closest thing to a constant — fire in four of the six, and the ambulance too everywhere except China. The police number is what changes at every border: 110, 112, 113 and 191 all mean the same thing in different countries.

eSIMs, rail passes, and airport transfers — the things worth booking before you land.
