Verifying users’ personal data online is of critical importance today to ensure the security of both users and platforms. Authenticating users is typically done through email addresses, phone numbers, or other unique information. These verification processes increase the reliability of accounts while also preventing the creation of spam accounts. In addition, the verification process protects users’ accounts and enables platforms to provide a more reliable service to their users. Nowadays, businesses use Node.js phone number validation applications for free phone number verification.

The phone number verification process generally relies on phone number verification APIs. These APIs were developed to verify users’ phone numbers. Using these APIs, businesses can verify phone numbers from more than one country in a single place. In this way, businesses verify the real identities of users and users can access their accounts more securely. In this article, we will first introduce a very popular free phone number verification API preferred by thousands of businesses. Then, we will develop a Node.js phone number validation application with this API.
