For tourism in Argentina and Paraguay, Brazilians may use a valid passport or a physical national ID card (RG or CIN) in good condition with a photo that clearly identifies the holder. Driving licences (CNH), professional cards and certificates are not accepted.

Under Brazil’s CNJ Resolution 131, a Brazilian child or teenager leaving the country without both parents (with only one, with third parties or alone) needs a travel authorisation, shown to the Federal Police on leaving Brazil in two originals (one is retained). If no validity is stated, it is valid for two years. Use the official CNJ form and guidance.
