What are Phone Verification Services?

Phone verification services are tools that help businesses validate phone numbers provided by users to ensure they are valid and active. These services typically use automated processes to check if a phone number is correct, reachable, and not associated with fraud or spam. Phone verification is commonly used during account sign-ups, transaction processes, or user authentication to prevent fake or incorrect information. These services often include features like SMS-based verification codes, automated voice calls for two-factor authentication (2FA), and number formatting checks. Phone verification is crucial for enhancing security, improving data quality, and reducing the risk of fraud.
