- Capital
- Jakarta
- Language
- Indonesian (Bahasa Indonesia) nationally, alongside hundreds of regional languages; English is widely spoken in tourist areas.
- Currency
- Indonesian rupiah (Rp, IDR)
- Cards and cash
- Cash still matters outside big cities and malls, though card and e-wallet payments are increasingly common in Bali and Jakarta.
- Entry and visas
- Visa-free or visa-on-arrival entry for up to 30 days for many nationalities including the US, Canada, Australia and UK, extendable once at an immigration office.

- Emergency number
- 112 for general emergencies nationwide, or 110 (police) and 118/119 (ambulance).
- Tipping
- Not obligatory, but appreciated — rounding up or leaving 5-10% at restaurants without a service charge is common practice.
- Safety
