How to Call Brazil from USA: A Step by Step Guide

Planning to call a friend in São Paulo, a family member in Rio de Janeiro, or a business partner in Brasília? International calling can feel intimidating the first time, with different country codes, varying number formats for mobile vs. landline numbers, and time zone arithmetic that can quickly turn a simple phone call into a confusing puzzle.

The good news: once you understand Brazil’s number format and the right dialing sequence, calling Brazil from the United States is straightforward. This guide walks you through every step, complete with examples, a full area code reference, time zone differences, cost breakdowns, and money-saving tips.

Brazil Country Code and Key Details 

Brazil’s country code is +55. It is the largest country in South America, officially known as the Federative Republic of Brazil (República Federativa do Brasil), with Brasília as its capital. 

It uses a structured telephone numbering plan administered by Anatel (Agência Nacional de Telecomunicações). Every number consists of an area code (called DDD- Discagem Direta à Distância) followed by the subscriber number. When calling from outside Brazil, you skip the domestic trunk prefix (0) and any carrier selection code entirely.

So, before dialing a Brazilian phone number, you need to know about the following key details: 

• Country code: +55
• Brazil phone number format: +55 XX XXXX XXXX (landline format) or  +55 XX 9XXXX  XXXX (Mobile number starts with 9)
• International format: 011 (from the US) +55 + XX (2-digits area code) + 9 (if mobile) + 8-digit number

Example: 

• +55 11 1234 5678 (Brazil phone number format locally)
• 011 55 11 1234 5678 (calling internationally)

How to call Brazil from USA (Step-by-Step)

To call Brazil from the USA, you need to use the correct international phone number format. The dialing process can change depending on whether you are calling a mobile phone or a landline. The main difference between the two is the length of the subscriber number.

Here’s the step-by-step guide to call Brazil from USA:

Calling Mobile Numbers

Brazilian mobile (cell phone) numbers always begin with the digit 9 after the area code, followed by the remaining digits of the subscriber number.

When dialing a mobile number from the US, follow these steps: 

• Step 1: Dial 011 (US international exit code), or you can also replace it with the “+” symbol.
• Step 2: Dial Brazil’s country code +55. 
• Step 3: Simply enter the 2-digit area code, i.e., For example, São Paulo is 11, Rio de Janeiro is 21, and Brasília is 61.
• Step 4: Dial the 9-digit subscriber number, as the mobile numbers always start with 9. 

For example: 011 55 11 9 8765 4321 where, 

• 011 = US exit code  
• 55 = Brazil country code  
• 11 = São Paulo area code  
• 9 8765 4321 = mobile subscriber number

Calling Landline Numbers

Brazilian landline numbers have an 8-digit subscriber number, one digit shorter than mobile numbers. The dialing structure is the same as mobile; only the length changes.

Steps to follow while dialing Brazilian landline phone numbers from the US: 

• Step 1: Dial 011 (US International Exit Code) or use “+” on a mobile device. 
• Step 2: Enter Brazil’s country code 55.
• Step 3: Dial the two-digit area code. For example, Curitiba is 41, Fortaleza is 85, and Porto Alegre is 51.
• Step 4: Finally, dial the 8-digit subscriber number. 

For example: 011 55 21 3456 7890 where, 

• 011 = US exit code  
• 55 = Brazil country code  
• 21 = Rio de Janeiro area code  
• 3456 7890 = landline subscriber full number

Brazil Area Codes 

Brazil uses two-digit area codes (DDD – Discagem Direta a Distância) ranging from 11 to 99 to identify specific regions, with major cities generally ending in 1 (e.g., 11 for São Paulo, 21 for Rio de Janeiro). Here is a list of major Brazilian cities and their city codes:

Time Zone Considerations When Dialing Brazil from USA

Brazil is a large country spanning multiple time zones, and the US is too, so the gap between the two countries varies depending on which cities you’re comparing. Brazil does not observe Daylight Saving Time, so the time difference can shift when the US enters or exits DST.

How much does it cost to call Brazil from the US?

The cost of calling Brazil from the US depends on the method you use, from expensive traditional carriers to completely free internet-based or VoIP apps. Here is a breakdown of each option:

• Traditional carriers: Rates for calling Brazil from the US through traditional mobile and landline providers typically range from $0.20 to $1.50 per minute, with mobile numbers usually costing more to call than landlines. Most carriers also charge additional international call fees, though adding an international calling package to your plan can noticeably lower the per-minute rate.
• Calling cards: Calling cards are prepaid and advertise low rates of call costs $0.02 to $0.15 per minute, but hidden fees, such as connection charges, maintenance fees, and per-call rounding, mean the real cost is often much higher than printed. They work without an app or internet connection, making them convenient for occasional calls, but the PIN entry process and inconsistent call quality are common drawbacks.
• VoIP services: VoIP services like KrispCall, Aircall, and Google Voice route calls over the internet, offering rates as low as fractions of a dollar per minute or flat monthly plans with unlimited calling to Brazil. Beyond low costs, they also include business-grade features such as call recording, call routing, analytics, and CRM integrations, making them the best option for businesses that call Brazil regularly.
• Free apps: Apps like WhatsApp, Facebook Messenger, FaceTime, and Viber allow free voice and video calls to Brazil, as long as both parties use the same app and have a stable Wi-Fi or data connection. While they are perfect for personal calls, they are not always the best fit for structured business workflows that require call tracking, routing, or integration with professional tools.

How to make calls to Brazil cheaper?

There are several practical approaches to reducing the cost of calling Brazil from the US. Each has its own trade-offs in terms of setup, call quality, and flexibility. Here are a few options that offer affordable calling options to Brazil: 

1. Use a VoIP service (e.g., KrispCall, Google Voice)

VoIP services route your call over the internet rather than traditional phone lines, offering per-minute rates that are a small fraction of carrier rates. VoIP service providers like KrispCall, for instance, provide Brazil virtual phone numbers with competitive international rates and business-grade call quality, ideal for both personal and professional use.

2. Call via WhatsApp or Messenger (Free Over Wi-Fi)

WhatsApp is extremely popular in Brazil; many Brazilians use it as their primary communication app. If both parties have the app and a decent internet connection, calls are entirely free regardless of distance. This is the most budget-friendly option for personal calls.

3. Choose an international calling plan

Major US carriers offer optional international add-on plans that significantly reduce per-minute rates. If you call Brazil regularly, a monthly add-on (typically $5–$15/month) can pay for itself after just a few calls compared to pay-per-minute rates.

4. Get a Brazil virtual phone number

A Brazil virtual phone number lets the Brazilian recipient call you at local rates, eliminating international charges for them, while you manage the number from the US. This is especially useful for businesses with clients or partners in Brazil.

Common mistakes to avoid when calling Brazil

Even experienced callers make errors when dialing internationally. Here are the most frequent mistakes people make when calling Brazil from the US, and how to avoid them:

1. Including the trunk prefix “0” or carrier code

In Brazil, domestic long-distance calls require a leading 0 followed by a 2-digit carrier code (e.g., 0 21 11 XXXX XXXX). When calling from the US, omit both entirely. Dial 011 55 [area code] [number], nothing else before the area code.

2. Dialing only 8 digits for mobile numbers

Brazilian mobile numbers have 9 subscriber digits (starting with 9), not 8. If you’re using an older contact that shows only 8 digits for a mobile number, add a 9 at the beginning of the subscriber number. Brazil added this digit to all mobile numbers in 2012.

3. Forgetting the US exit code (011)

To place any international call from a US landline, you must start with 011. Skipping it means your call will not route internationally. On mobile phones, you can use “+” instead, but you must have one or the other.

4. Confusing the country code with the area code

Brazil’s country code is 55, and São Paulo’s area code is 11; they’re different numbers with different roles. Always dial both: 011 (exit) → 55 (country) → 11 (area) → subscriber number. Omitting or combining these will result in a failed call.

5. Expecting toll-free numbers to work

Brazilian 0800 numbers are free within Brazil, but they may not accept international calls at all, or may charge you standard international rates even if they do connect. Always use the regular geographic number when calling from abroad.

6. Ignoring the time zone difference

Brazil is 1–4 hours ahead of the US. A 9:00 AM New York time call is 11:00–12:00 AM in most of Brazil, which is still fine for business. But calling in the early morning US time could wake someone up in the middle of the night in Brazil. Always check the time before dialing.

Wrapping Up

Calling Brazil from the United States is simple once you know the formula: 011 + 55 + area code + subscriber number. The key differences to remember are that mobile numbers have 11 digits (and always start with 9 after the area code), while landline numbers have 10 digits. Never include the domestic trunk prefix or carrier code; those are for calls made within Brazil only.

For the most cost-effective calling, consider using a VoIP service like KrispCall, a free app like WhatsApp, or a virtual phone number in Brazil if you communicate with Brazil regularly. Always check the international phone number format guide for the country you’re calling from when making international calls.
