What is the difference between enterprise SMS verification code and voice verification code?

Difference 1: The receiving method is different.

SMS verification code means that users fill in their mobile phone numbers and send a string of verification code numbers to their mobile phones through websites. Users fill in the verification code on the website to complete the verification, which can effectively avoid malicious registration and ensure that the obtained customer's mobile phone number is the most authentic;

Voice verification code is also used by users to input the mobile phone number, but the number of verification code is heard by customers in the form of answering the phone to complete the verification service, which can avoid being intercepted by mobile phone short messages and improve the success rate of user registration.

SMS verification code and voice verification code are received in different ways, so you can choose either one without being too entangled.

Difference 2: The user experience is different.

The SMS verification code is sent to the user's mobile phone in the form of SMS. Sometimes, because the sms channel used by the third-party SMS platform you choose is not very stable, the sending of SMS verification code will be delayed or not received, which will affect the user experience. The solution is to choose a regular and reliable SMS provider. The channels they use are all dedicated channels for SMS verification code, and the sending speed and arrival rate of SMS can satisfy users.

The voice verification code is obtained by answering the phone. Although the connection rate is generally acceptable, there are also cases where customers think that they are harassing calls and refuse to answer them. Moreover, it is not very convenient to answer the phone during working hours or when there are many people, and the user experience will not be too good.

Both have their advantages and disadvantages. In order to improve the customer experience, most enterprises can use them in a complementary way.
