What documentation do I need to cross to Brazil?
Argentine citizens
Argentines can enter Brazil with a valid national ID card (DNI) only. Important: the ID must be the plastic card format, not the old green booklet. The ID must not be expired.
It is recommended to carry your passport as a backup document, especially if you plan to cross through multiple border checkpoints or if your ID is close to expiring.

A valid passport is required. Some countries require a visa to enter Brazil as tourists. We recommend checking with the Brazilian consulate for your nationality before traveling.
Minors (under 18)
- Traveling with both parents: only need their ID.
- Traveling with one parent only: notarized authorization from the other parent is required.
- Traveling alone: notarized permission signed by both parents (no more than 90 days old).
