How Does a Phone Verification API Work

You must have seen that a phone number is requested during registration on an application or website. The accuracy of the mobile phone number entered by the users during registration is very important for the application. Wouldn’t you like to learn how your system will detect a user who wants to register to the system with a missing character or an incorrect number? Read on to learn about a phone number verification API.

Especially if users from many locations around the world are using your application, this means verifying the number of more than one country code. At first glance, it sounds both costly and difficult. There are many options available to solve this situation. The most effortless and simplest of these options would be to add a service that provides phone verification API service to the application layer.

By integrating the phone verification API services into the application, there is no need to set up any structure for number verification processes on the application side. The application is completely abstracted from the number verification processes and the service providing the phone verification API service, which you will integrate into your application, undertakes this task.

There are many services in the market today that provide phone verification API service. These services mostly operate on the same working principle. In this article, we will talk about how the phone verification API service, which can be integrated into applications, works.

How To Verify a Phone

In order to perform number verification through the application, you first need to integrate a service that provides phone verification API service to your application. There are many services on the market that provide phone verification services, and one of the most popular of these services is the Numverify API.

To actively use a phone verification API that you have integrated into your application, you need to send the phone number that users entered during registration and the country code depending on the phone number to the phone verification API service.

An example phone verification API service is as follows, and the phone number that the user enters from the application and the country code depending on the phone number should be added to the fields indicated and the request should be made.

    ? access_key = YOUR_ACCESS_KEY
    & number = USER_PHONE_NUMBER
    & country_code = USER_PHONE_NUMBER_COUNTRY_CODE

After preparing and running the sample phone verification API request, this service makes inquiries for this phone number from the official sources of the country belonging to the country code the user entered in order to provide reliable information. If the query result obtains information about this phone number, ‘valid’ is returned as the query response. If this number is incorrect and not valid, you will receive detailed information at this stage and you will be able to inform your users through the application.

One of the most preferred methods of number verification is verification by SMS. It is very important to use services that provide phone verification API for these transactions. After asking the official sources for the phone number entered by the user through the application and the country code linked to the phone number, if this number is valid, the verification step is started by SMS. The main purpose of verification by SMS is to confirm whether the verified number entered by the user belongs to the user.

Conclusion

With the services that provide phone verification API services, it is quite possible to verify the number of your users without installing any structure on the application layer. You can attract users from almost anywhere in the world, especially by integrating a service that supports 232 country codes around the world, such as Numverify API, into your application.
