Methods of Phone Number Verification

Phone number verification is a critical process for confirming the authenticity of phone numbers, vital for security and trust-building in various online interactions. Typically, methods include SMS verification, where users receive a one-time passcode via text message, voice call verification using automated calls to deliver codes, and missed call verification, where users confirm ownership by acknowledging missed calls. Additionally, number validation services authenticate numbers in real-time, checking their format, validity, and carrier information.
