Cultural Tip
In Brazil the official emergency numbers are 190 (Polícia), 192 (SAMU – ambulance) and 193 (Bombeiros). Misusing them can result in a fine, so only call when there is a genuine emergency. In Portugal the single number 112 connects you to all emergency services. Knowing the local number and the correct phrasing shows respect for local protocols and can save lives.
