- Currency
- The Brazilian real (BRL). Bank cards, including contactless, are accepted in most shops, restaurants and hotels, but cash is useful at beach stalls and small markets.
- Sockets
- Sockets of types C and N are used. Voltage depends on the state: 127 V or 220 V, frequency 60 Hz. Check that your charger is rated for 100–240 V and bring an adapter.
- Emergency
- Main numbers: 190 for police, 192 for ambulance, 193 for the fire service. Save them and your accommodation address before a trip into nature.
- Time difference
- Time in Brasília and most resorts is 8 hours behind Kazakhstan: when it is noon in Astana, it is 04:00 in Rio. Brazil does not switch to summer time, but in the Amazon the difference with Kazakhstan is 9 hours, and on Fernando de Noronha 7 hours.
- Language
- The official language is Portuguese. In tourist places staff often speak English, but elsewhere you will need a translator or a few memorised phrases.
- Beach and humidity
- Take your phone to the beach in a waterproof case and carry few valuables. Humidity and sun drain the battery fast, so a power bank is useful.
- Water and tipping
- Many travellers drink bottled water. Restaurants often add a service charge to the bill, so check the receipt before leaving a tip.
- Entry
- Check current entry rules for citizens of Kazakhstan before the trip.
