# Mobile identity verification
**Mobile phone identity verification service** is used to confirm the identity of the user and the accuracy of the user's identity information submitted through the mobile phone under the user's name.
User's identity verification is needed to sign up for websites, make payments, or verify age. You can perform identity verification by using the identity verification app installed on a mobile device, or by submitting your identity information (**name, date of birth, mobile phone number**) through the verification request page and then confirming the verification number received via text message.
The flow of i'mport mobile identity verification involves performing verification using the JavaScript SDK and then the merchant server **retrieving the verification result** using the ChaiPort REST API.
