55 Country Code: Brazil (+55)
+55 is the country code for Brazil. If you searched "55 country code", "country code 55", "0055 country code", or "+55 country code" — they all refer to Brazil. The code is also called the 55 dialing code, 55 phone code, or 55 ISD code, and is assigned by the International Telecommunication Union (ITU) under the E.164 standard.
Brazilian phone numbers use a 2-digit area code (DDD) — São Paulo 11, Rio 21, Brasília 61 — followed by the local number. Since 2016, all Brazilian mobile numbers have been 9 digits, always starting with 9 (so an 11-area-code mobile looks like +55 11 9XXXX-XXXX). Landlines remain 8 digits after the area code. The domestic long-distance format uses a carrier selection code (e.g. 0 21 21 for Rio via carrier 21), but these are never dialed internationally.
