What Is a Short Code?
It refers to a short number that is used by businesses for sending and receiving SMS (Short Message Service) texts. In the US, a common SMS code usually consists of five or six digits, and, unlike regular phone numbers, it is created specifically for sending and receiving tons of text messages and interacting with customers in a simplified way.
Taking an example of a retail outlet, the outlet can ask its customers to text the code with the keyword JOIN if they want to receive deal alerts. The keyword can also be sent to enter a contest, get a coupon, or obtain product information.
What Are the Different Types of Short Codes?
Depending on their messaging requirements, brand and budget, businesses can opt for several different kinds of codes.
Dedicated Short Codes
A dedicated short code is exclusive to one business or company. It helps the business better control messaging campaigns, keywords, and customer interactions. Businesses that send high message volumes will often opt for dedicated ones to ensure their brand messaging remains consistent.

A shared short code is one that various businesses can use. Each business has a variety of unique keywords to identify the different campaigns. These are less popular in the US as most of the major carriers have capped or eliminated many shared-code messaging campaigns.
Vanity Short Codes
It is a number with easy-to-remember digits or a number that is associated with your brand. This number helps companies brand their logos as well as their messaging campaigns.
Random Short Codes
A random code is a number provided by a messaging provider or carrier, instead of a number that is specifically targeted for branding purposes. The random code has similar messaging capabilities to other dedicated codes without the need for a memorable number.
How Does Short Code Texting Work?

Short code texting enables a customer and business to communicate with each other by sending text messages to a shared number. The basic process usually includes a messaging provider, a mobile carrier, and the customer’s mobile device. The process follows these steps:
- Register Your Code: A business that chooses an available code registers with a messaging provider for approval.
- Set Up Campaign Details: The company establishes message content, keywords, target audience, and timing for delivery.
- Gather Consents from Your Customers: Customers opt in by texting an identified keyword or filling out a web-based form, or utilizing some other approved method to opt in.
- Send Messages: The business will send promotional messages, reminders, alerts or other relevant messages to people who have opted in.
- Control Responses: Customers can reply with supported keywords, ask questions, or unsubscribe using the controls the campaign has established.
For instance, a customer sends JOIN to a code associated with a business and receives a confirmation message. The business can then send follow-up messages or notify the customer of updates based on a customer’s subscription and opt-in preferences. Customers can generally send STOP to unsubscribe.
