Adding phone verification to your app or website can help protect users from fraud and data breaches. It can also be a valuable way to learn more about your customers and how they use your service.
SMS verification offers a number of benefits including ease of use, affordability, and speed of delivery. But, it’s not without its challenges.
Verify a User’s Phone Number
Using mobile phone verification to confirm a user’s identity can help reduce fraud and improve security. The process is simple and intuitive for users, while providing companies with valuable insights about their audience.
SMS identity verification requires a user to receive a one-time passcode via text or call and enter it into a web form or app. It’s the most common 2FA method and is available to nearly everyone in the world. SMS is easy to use, quick and secure — but can be expensive at scale.
Flash Call and Voice Verification offer alternative experiences to SMS, which are more automated, streamlined and scalable. Both provide greater insight into a user’s risk profile and can be used for 2FA, password resets, reactivation, and more. They are also more cost-effective than SMS. Combined with advanced analytics, they are a powerful tool for verifying users and increasing the value of your business.

Verify a User’s Email Address
Using phone verification, you can confirm that a user’s email address is valid. This method typically sends a one-time passcode to the user’s phone number, which they then enter on the application or website to verify their identity and link their device with the correct account. This is a common and simple form of two-step verification (TOTP).
Phone verification helps to prevent fraud by ensuring that the person who is trying to access an account or service is a real human being, not a bot or a scammer. It also helps to protect users’ privacy by ensuring that their phone numbers are not being used for unwanted marketing messages or spam. It’s important to work with a phone verification service that is SOC 2 compliant to ensure that the code delivered to your users’ phones is secure and can’t be intercepted. Especially, when sending time-sensitive one-time codes to thousands of people at once. This is a common attack vector for attackers.
Verify a User’s Social Media Accounts
Adding mobile phone verification to your website or app can help protect you from fraud and abuse. It’s a quick, easy way to confirm that a user is who they say they are. But there are pros and cons to this method, and it’s important to consider how you will communicate with users about sharing their phone number with you.
SMS verification is the most common and easiest for users to understand. It requires a user to receive a one-time passcode via SMS and then enter it in order to verify their identity.
However, this verification method can be vulnerable to man-in-the-middle attacks, SIM swapping, and phishing. It also depends on real-time connectivity, and users may be reluctant to share their phone numbers due to privacy concerns or fear of being bombarded with marketing texts.
Verify a User’s Online Accounts
For apps and sites that require a high level of security, phone verifications help establish identity and evaluate risk with little or no consumer involvement. This type of security solution can prevent fraud and abuse by ensuring that the user’s mobile phone number belongs to them and is linked to their online accounts.
When a user registers with an app or website, they will be sent a time-sensitive code via SMS or voice call to verify their phone number. They then enter this code into the application to complete registration. This type of phone verification is also known as SMS authentication or 2FA.
