Short answer
No, there is no Brazilian consulate in the Azores. Brazilian citizens in the islands are served by the Brazilian Embassy in Lisbon and its consular section, which handles passports, notarial acts and other services, usually by appointment and sometimes by post. For urgent matters, check the embassy's official website for current procedures and whether any mobile consular service visits the Azores.
