Do you also receive a call and wonder, ’ Which operator is this number?’ In Brazil, tracing the owner of a phone number is relevant, considering the portability of numbers and differentiated calling rates. To help you spend less time and money, it is often wise to check the carrier to avoid being charged some money without prior knowledge of who you are calling.
Luckily, one can find a lot of trustworthy and legitimate sources of getting this information, including official portals, apps, and regional service codes. This is a Brazilian user guide that explains all the methods to query cell phone operators in detail, step by step.
Why Check the Operator Before Calling?
Knowing the carrier before making a call in Brazil prevents:
- Unexpected charges: Domestic calling (the same operator) may be cheaper.
- Portability surprises: Numbers may have changed suppliers and rate plans.
- Plan optimization: Helps you select the optimal rate plan or bundle.
- Prevention of surcharges: Calling outside the operator may incur fees.
- Higher quality communication: Appreciate when applied (e.g., VoIP, via an app).

We will take you through the seven tested ways, such that by the time you pick up the phone, you already know who you are dealing with on the other end.
Query the ABR Telecom Website
The official portal of ABR Telecom is a free and administratively controlled tool designed to assist users in finding the current operator of any Brazilian number- mobile or landline number. It is particularly useful because of the number portability mechanism in Brazil; thus, an individual can port his or her number. The system also provides portability history to provide proper and open carrier information.

Use Operator Query Tools
Operator query tools are fast, user-friendly websites that help you identify the mobile or landline carrier of any Brazilian number. They’re essential for avoiding unexpected charges before calling.
QualOperadora
QualOperadora is one of the lightweight Brazilian websites that allows its users to determine the operator of any mobile or landline phone. It is perfect to avoid surprise bills when dialing various carriers. The service not only identifies the carrier, but you can also see whether the number is ported and the area it belongs to.

Identify Carrier Selection Codes (CSP)
Carrier Selection Codes (CSPs) were once essential for choosing a long-distance operator in Brazil. Though less used today, these codes still help identify a number’s original or default operator, especially for older or ported numbers. Recognizing CSPs can offer insight into a user’s long-standing telecom provider or call routing path.
- Note the CSP code used during a long-distance call (e.g., Rio de Janeiro 21, região Sul 31).
- Cross-reference with known operator codes.
- Use it as an indicator of default or previous carrier.
Download the Whoscall app
Whoscall is a reliable caller ID and spam blocker utilised in Brazil and Asia. It has an enormous database of phone numbers and has the capability of going back and determining unknown calls in real-time with the information about carriers. It improves call safety, performs operator verification, and blocks scams with the assistance of a government and AI-based filtering.
- Download from Google Play or App Store.
- Grant access to your contact and call data.
- Let the app display caller and operator info live.

Use WhatsApp to Identify the Operator
Although WhatsApp does not necessarily indicate the operator of a number, it is able to provide indications. When you add a number to your contacts and run it in WhatsApp, the portrait, status, and phone code can indicate the geographical location and the mobile network. It is a fast, easy trick, especially when it is used together with number formatting and CSP clues.
- Save the number in your phone’s contact list.
- Open WhatsApp and start a new chat.
- Observe the profile image and info.
- Use clues for identifying the possible operator.
Query Operator by Number
Sites such as Cellphone Location offer a robust reverse phone lookup service tailored to Brazilian customers. Not only do they identify the type of operator (Claro, TIM, Vivo, Oi, etc.), but also display the name of the owner, email, address and even the risk of spam he has. This can be used to authenticate unfamiliar numbers and prevent scams, or to interrogate VoIP lines.
- Enter the Brazilian phone number with the country code.
- Hit “Search.”
- Enter your email address to view operator, VoIP/fixed/mobile status, and more.
- Use the info to decide whether to call or block.
Verify Number Portability
Number portability enables subscribers to move to a different operator without changing their number and therefore it is more difficult to determine the service provider by prefixes. The official site of ABR Telecom provides precise, real-time information to confirm the current carrier of any number both in the mobile and in the fixed world, so as to prevent unexpected billing shocks or incompatible network services.
- Visit ABR Telecom’s consultation site.
- Enter the phone number (with DDD).
- Complete the CAPTCHA.
- Click “Consultar.”
Can I Find out the Operator of a Landline Number?
Yes, you can find out the operator of a landline number in Brazil using the ABR Telecom portal. The platform doesn’t limit its services to mobile numbers—it also includes landlines.
Simply visit the ABR website, enter the DDD (area code) followed by the landline number, complete the CAPTCHA, and click Consultar. The system will display the current operator along with any portability history, showing whether the number has switched providers.
This is particularly useful for identifying the correct service provider before placing business or personal calls to fixed-line numbers, helping avoid miscommunication or unexpected charges.
