55 Country Code: Brazil (+55)
Country code 55 (+55) belongs to Brazil. Brazil uses the international dialing code +55, assigned by the International Telecommunication Union (ITU) under the E.164 standard. The ISO 3166-1 alpha-2 code is BR.
You will see the same code written several ways depending on origin: +55 (universal + prefix, works from mobile), 0055 (from countries that use 00 as their international exit code — most of Europe, Asia, and Latin America), 011 55 (from the US and Canada), 0011 55 (from Australia), or the bare 55. All refer to the same Brazil country code.
Other ways people search for the same thing: "country code for brazil", "brazil country code", "brazil international code", "brazil phone code", "brazil dial code", "brazil dialing code", "brazil country prefix", "+55 country code", "55 country code", "0055 country code", "how to call brazil from us", "what is the country code for brazil", "what country code is 55", "brazilian country code", "brasil country code", "codigo de pais brasil". All of these resolve to +55 for Brazil.
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.

Calling Brazil Successfully: Common Mistakes & Best Practices
Most failed calls to Brazil come from one of four mistakes, not from network problems. The most common is mishandling the leading 0: domestically, Brazil numbers are written with 0 at the front (e.g. 011912345678), but that 0 is the domestic trunk prefix and must be removed when calling from outside Brazil. Dial +55 followed directly by the local number without the 0.
The second is misreading the area code on landline numbers — Brazil area codes are not uniform length (São Paulo 11, Rio de Janeiro 21, Brasília 61), so confirm the city before dialing. The third is dialing during off-hours — Brazil uses Portuguese business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +55 is the legitimate Brazil country code, and most unsolicited calls from +55 numbers are legitimate calls from Brazil-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +55 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
