A text verification code usually contains 4 or 6 digits, which are sent to the recipients’phone, to verify the identity of the recipient. This code is sent through text messages, to prove the phone number is valid.
The reason that the merchants send text verification codes is to make sure the phone number is valid, which will be part of the customer data stored by the merchants. The merchants can use customers’phone numbers for further promoting activities.
Meanwhile, when someone steals an account and password and wants to do illegal things with it, for example, make a payment. At this time, the merchant must require a text verification code since this can only be received by the account owner. In this way, a text verification code can double-check the identity of the user and prevent potential loss.
Nowadays, with the convenience and low costs of bulk text messages, most merchants choose SMS messaging for verification, marketing, and promoting methods. It is the most direct way for the merchants to communicate with the customers.
