How Does Numverify Validator API Work?

how does numverify validator api work

The first step in using the numverify validator API is to input the phone number that needs to be validated. This can be done via an API request that includes the phone number. However, firstly we must have an account on the numverify website since it will give us an API key. Using that API key, we can use and integrate the numverify API into our application.

It’s very simple to make a number verification request to the numverify API. This is an example of a most basic API request:
    ? access_key = YOUR_ACCESS_KEY
    & number = 14158586273

Numverify validator API checks the phone number against pre-defined rules to ensure it is in the correct format, including the correct country code, area code, and prefix. This helps to identify any errors in the phone number and eliminate them.

After the phone number is validated, the numverify phone number validation API verifies the phone number information, such as whether the number is active, the carrier, and the geographic location. This helps to ensure that the phone number is correct and up-to-date.

Once the phone number is validated and verified, numverify API returns the results of the validation and verification process. This can include information such as whether the phone number is valid, the carrier, the location, and other relevant information. For instance, we can see an example response returned through numverify under:

    "valid": true,
    "number": "14158586273",
    "local_format": "4158586273",
    "international_format": "+14158586273",
    "country_prefix": "+1",
    "country_code": "US",
    "country_name": "United States of America",
    "location": "Novato",
    "carrier": "AT&T Mobility LLC",
    "line_type": "mobile"

Understand the API Documentation

It is extremely important to carefully read and understand the API documentation before using a validator API. This can help us understand the capabilities the API offers, usage limitations, and the correct syntax and formatting required for API requests and responses. API documentation usually contains detailed information on the use of the API, allowing users to integrate the API correctly and use it most efficiently. Therefore, it is important to carefully review the API documentation and refer to it when necessary to ensure correct and effective use of the API.

Validate Data at the Source

To ensure the highest data accuracy, it’s best to validate data at the source. This means validating phone numbers as they are entered or collected rather than waiting until later in the data processing workflow.

Use Validation Rules

This can help to eliminate errors and inconsistencies and improve the accuracy of our data.

Set Up an Automated Validation Process

To ensure consistent and accurate data validation, it’s best to set up automated validation using an API like numverify validator API. This can help save time and reduce errors in data processing workflows.

Monitor Results

It’s essential to monitor the data validation results to ensure that it works correctly and provides accurate results. This can help identify any issues or errors that may arise and allow for a quick resolution. We must be able to parse the JSON response in the results.

Maintain API Security

Ensure the API is secured with proper authentication and encryption to protect sensitive data from unauthorized access or interception.


To sum up, data accuracy is a fundamental element for businesses to operate effectively. Phone number validation API services such as numverify play an important role in improving data accuracy. Such APIs prevent directly invalid or incomplete data entries by checking the validity of the phone numbers entered by users.
