According to a report, the number of mobile users worldwide is expected to reach 7.49 billion by 2025. Phone number verification has emerged as a reliable and efficient method for validating user identities and mitigating fraud risks. 

By leveraging this process, organizations can establish trust, enhance security and ensure regulatory compliance, paving the way for seamless user interactions.

‍

What is Phone Number Verification?

‍

Phone number verification is a process that confirms the validity and ownership of a phone number provided by a user. It serves as an additional layer of security, ensuring that the individual claiming ownership of the number is indeed in possession of it. 

This verification process typically involves sending an OTP SMS or a verification code to the user's phone, which they must enter or confirm to complete the authentication process.

‍

The primary objectives of phone number verification are

1. Validating User Identity

By verifying the phone number associated with a user account, businesses can establish a stronger link between the individual and their digital identity, reducing the risk of impersonation or fraudulent activities.

2. Enhancing Security

Implementing phone number verification as part of a multi-factor authentication (MFA) process significantly increases the overall security of user accounts, making it more difficult for unauthorized individuals to gain access.

3. Regulatory Compliance

Many industries such as finance, healthcare and e-commerce, are subject to stringent regulations that mandate strong identity verification measures. Phone number verification helps organizations meet these compliance requirements.

4. Fraud Prevention

Fraudsters often use fake or stolen phone numbers to circumvent security measures. By verifying phone numbers, businesses can detect and prevent potential fraudulent activities before they occur.

How to Verify a Phone Number?

‍

Following are the steps to verify a phone number
‍

1. User Provides Phone Number

During the registration or authentication process, the user is prompted to enter their phone number.

2. Number Validation

The provided phone number undergoes an initial validation check to ensure it adheres to standard formatting rules and is not associated with known fraudulent activities.

3. OTP Generation and Delivery

If the number passes the initial validation, a one-time password (OTP) or verification code is generated and sent to the user's phone via SMS or voice call. You can setup this process of SMS verification with providers like Message Central.

4. User Input and Verification

The user enters the received OTP or verification code into the designated field within the application or website.

5. Verification Confirmation

The system compares the user-entered code with the one sent to the phone number. If they match, the phone number is considered verified, and the user can proceed with the desired action or gain access to the requested resources.
