What is SMS code: explanation, tips and benefits

If you want to know what is SMS code, you’ve come to the right place.

In the US, it’s a 5- to 6-digit phone number that can be used for exchanging short messages and/or two-factor authentication purposes.


Why use a SMS Code

Industries like retail, banking, NGOs, and the Internet are usually in need of a system that help them confirm the identity of a person.

For example, an online retail store may need to send a 6-digit verification code to a customer’s mobile phone number before a credit card transaction can be made. By doing so, the retailer can have a way of getting someone’s proof of identity.

On the other hand, if it’s your intention to use a code for a marketing campaign, it’s advisable to lease a 5- to 6-digit short code where customers can then text their messages to. Plus, it’s obviously shorter than telephone numbers so people should be able to read and remember it easily.

However, carriers lease out these SMS codes to SMS gateway companies and then make it accessible to its customers. This is why getting a code may cost you extra, especially if you’re going to use it for high volume applications.



SMS codes, whether for verification or mass text messaging purposes, will only work for individuals who have a mobile device that is capable of receiving such messages.

While most smartphones nowadays do have this capability, people who only have landlines in their houses cannot receive SMS. One way to get around this issue is by using a voice verification messaging system.

To recap what is SMS code, it’s a short digit number that can be used for identify verification and text messaging.

Companies in need of communicating with a large number of customers on a regular basis will find great use of this system. Similarly, smaller businesses can also use SMS code to automate their text messaging service like subscription, opt-out, and text-to-win programs.
