Customer targeting mainly plays an important role in personalizing marketing campaigns, tailoring products and services to customer needs, and even strengthening customer loyalty. The right customer targeting strategies can help companies not only retain existing customers but also acquire new customers.

In this article, we will take a closer look at free carrier lookup services and their advantages, which help develop telecommunication strategies and target customers. Then, we will introduce today’s most popular free phone carrier lookup service.

Understanding the Free Carrier Lookup Service

Carrier lookup service is one of the most important tools of recent times that plays a vital role in many sectors, especially the telecommunications sector. Chiefly, carrier lookup is a service to determine which telecommunications carrier a phone number belongs to. This can help businesses better understand customer information, perform telecommunication data analysis, and identify their target audiences more effectively. Carrier lookup service makes a significant contribution to optimizing marketing strategies and improving customer targeting processes by quickly and accurately providing operator information associated with the phone number.

The spread of customer targeting with carrier lookup free API has led to an increase in the number of providers providing services in this field. The carrier lookup service has become easily usable, usually integrated via API (Application Programming Interface), and available on various platforms. This service is used outside of telecommunications businesses, especially in mobile applications, communication platforms, and customer relationship management systems to help businesses enrich customer information. Having accurate and up-to-date operator information is critical to making direct marketing campaigns more personal and delivering content appropriate to the target audience. It also has the potential to provide special operator-related offers or services, enhancing the customer experience.

However, for an API providing this service to be effective, accurate data and a reliable infrastructure are needed. It must also be suitable for global use and support phone numbers from more than 200 countries around the world. Keeping operator information up-to-date and accurate enables businesses to be successful in customer segmentation, marketing strategies, and operational processes. Additionally, customer privacy and data security should also be considered and appropriate precautions should be taken when using this service.

Telecommunication strategies are an indispensable step for success in today’s business world. Carrier lookup services, which are used to develop these strategies and improve customer targeting, offer various advantages to businesses. In this section, we will discuss some common use cases where these services are used and their advantages.

Use of Operator Information in Customer Segmentation

Carrier lookup services provide telecommunications companies with a useful resource for customer segmentation. Thanks to this service, a company can identify customer groups with different operators by enriching its customer database with operator information. This is one of the main advantages of carrier lookup services. For example, a mobile communications company can understand which operator’s customers tend to use more data and offer special offers to these customers with special data packages or campaigns. In this way, customer segmentation becomes more effective and marketing strategies better suit customer needs.

Strengthening Customer Relationships and Improving Experience

Carrier lookup services can help businesses strengthen customer relationships and improve customer experience. This service, which is used especially in call center operations, allows customers to provide more personalized support by determining which carrier they are contacting. For example, an e-commerce platform can make recommendations specifically for the carrier customers use, thereby increasing customer satisfaction.

Phone Number Verification and Fraud Prevention

Carrier information is a simple way to verify your phone number. In this way, it is also useful in terms of security and fraud prevention. For example, when a bank customer enters his phone number, the bank can find out whether the customer’s phone number is valid or not, thanks to the carrier lookup service. This adds an additional layer of security to detect and prevent potential fraudulent attempts on users’ accounts.

Get a Free API Key

The first step to start using the numverify API is to obtain an API key. It offers us flexible subscription plans. It also has a free plan. Numverify’s free plan is limited to 100 API requests per month. It does not require any credit card information in its free plan, allowing its users to start testing quickly. In this step, we will sign up for the free plan and obtain an API key.


After signing up for the free plan and obtaining a free access key, we can start using the numverify API. The numverify API URL we will use in this integration is as follows:
    ? access_key = FREE_ACCESS_KEY
    & number = 14158586273

With this API URL, we will obtain detailed information about the number ‘14158586273’. To integrate this API URL into the Java programming language, let’s open a Java application and put the following codes in the class with the ‘main’ method:

public class Main {
  private static final String ACCESS_KEY = "FREE_ACCESS_KEY";

  public static void main(String[] args) {
      String phoneNumber = "14158586273";
      String apiUrl = buildApiUrl(phoneNumber);

      try {
          String apiResponse = sendHttpGetRequest(apiUrl);
          System.out.println("API Response: " + apiResponse);
      } catch (Exception e) {

  private static String buildApiUrl(String phoneNumber) {
      return "" + ACCESS_KEY + "&number=" + phoneNumber;

  private static String sendHttpGetRequest(String apiUrl) throws Exception {
      URL url = new URL(apiUrl);
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();


      int responseCode = connection.getResponseCode();

      if (responseCode == HttpURLConnection.HTTP_OK) {
          try (BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
              StringBuilder response = new StringBuilder();
              String inputLine;

              while ((inputLine = in.readLine()) != null) {

              return response.toString();
      } else {
          throw new RuntimeException("API Request Failed. Response Code: " + responseCode);


Before testing the application, let’s put our API key in the ‘FREE_ACCESS_KEY’ field and run the application. The JSON response we obtained is as follows:

  "valid": true,
  "number": "14158586273",
  "local_format": "4158586273",
  "international_format": "+14158586273",
