Your First 24 Hours in Argentina

  • ✅ Set up CacaoCash before you fly — takes under 5 minutes, verification may take a few hours.
  • ✅ Load your CacaoCash wallet with USD 200–500 to cover your first few days.
  • ✅ Exchange a small amount of USD cash at the airport or a casa de cambio for immediate cash needs (taxis, tips).
  • ✅ Notify your home bank that you're traveling so your cards aren't blocked.
  • ❌ Don't exchange currency at the official airport exchange counters — rates are the worst in the city.
  • ❌ Don't hand your card to a street vendor or unofficial "cambio" tout on Calle Florida.

Key Terms Every Argentina Traveler Should Know

  • CBU — Clave Bancaria Uniforme. The 22-digit number that identifies an Argentine bank account. Like an IBAN.
  • CVU — Clave Virtual Uniforme. The equivalent identifier for digital wallets (Mercado Pago, MODO, etc.). Works the same as CBU for transfers.
  • Alias — a human-readable name (like "name.word.word") that replaces the CBU/CVU for transfers. Easier to share verbally.
  • DNI — Documento Nacional de Identidad. Argentina's national ID. Required to open local bank accounts and digital wallets.
  • CUIL/CUIT — tax identification number. Issued to workers (CUIL) and businesses (CUIT). Linked to DNI.
  • SUBE — the national transit card used for buses, subways, and trains in Buenos Aires and other cities. Can be loaded at kiosks and Mercado Pago. Not accessible to foreigners without a local wallet.
  • Dólar MEP — legal parallel exchange rate accessible through stock operations. About 1–3% above official in 2026.
  • Dólar blue — informal parallel exchange rate. About 2–5% above official in 2026. Not worth the risk for small amounts.
  • Cepo cambiario — currency controls. Largely dismantled under Milei, though some restrictions remain.

When to Use What

  • Restaurant, café, supermarket → CacaoCash QR
  • Street food, markets, taxis → CacaoCash QR or cash pesos
  • Hotel, car rental, airline → Credit card
  • Large cash purchase → Casa de cambio for pesos, then cash
  • Emergency cash → ATM (last resort, withdraw maximum)

What to Avoid

  • ❌ Airport exchange counters (worst rates in the city)
  • ❌ Hotel exchange services (almost always worse than casas de cambio)
  • ❌ Exchanging money with strangers on the street (counterfeit risk)
  • ❌ Multiple small ATM withdrawals (each one costs $8–15 in fees)
  • ❌ Trying to open a Mercado Pago account without a DNI (it won't work)
