What Is A Short Code? A Complete Explain

What is Short Code

Communication is vital in connecting people, businesses, and organizations in this digital age. One significant aspect of modern communication is the use of shortcodes. Short codes are unique numerical or alphanumeric sequences facilitating various communication functions, including text messaging, marketing, and customer engagement.

Moreover, eliminating third-party cookies has presented significant challenges for e-commerce businesses in marketing. Numerous marketers find themselves at a loss without the ability to rely on targeted ads.

However, the situation is not without hope. It necessitates a pivot towards adapting and capitalizing on emerging channels for customer outreach and engagement. In this regard, SMS is an exceptionally effective channel for these purposes.

Shortcodes for SMS serve as a fundamental tool for executing SMS marketing campaigns. Therefore, it is essential to clearly understand how they work and their significance in this context.

What Is An SMS Short Code?

An SMS short code is a concise numerical sequence businesses utilize for efficient and scalable text message communication, typically consisting of five or six digits. These shortcodes replace regular 10-digit phone numbers and offer faster sending speeds, making them ideal for delivering targeted and personalized messages to a large subscriber base.

One primary application of shortcodes is facilitating the opt-in process for SMS marketing programs. Customers can initiate communication with a business by sending a keyword to a short code. Upon doing so, they are enrolled in the program and can start receiving automated and personalized responses to their text messages.

The most significant advantage of shortcodes lies in their simplicity, which enhances customer-brand communication. With just five or six digits to remember, instead of a total ten-digit phone number, customers find it convenient to engage with a business by simply grabbing their phones and opting in.

How Do Short Codes Work?

Shortcodes operate within the framework of the mobile telecommunications network, making them a powerful tool for various communication purposes.

The basic working principle of shortcodes involves the following steps:


Organizations or service providers apply for shortcodes through the United States regulatory bodies, such as the Common Short Code Administration (CSCA). They specify the intended use of the code and pay the required fees.


Regulatory bodies review applications to ensure compliance with rules and regulations. Once approved, the organization or service provider can access the shortcode.


The short code is activated on the mobile network, making it accessible to users.

User Interaction

Users can initiate interactions with the shortcode by sending a text message from their mobile devices.


The mobile network recognizes the short code and routes the message to the appropriate destination, such as a server or application managed by the organization or service provider.


The organization or service provider’s system processes the incoming message, generates an automated response, and sends it back to the user. This response can include information, confirmation, or further instructions.

What Are The Uses Of SMS Short Codes?

Shortcodes simplify the process of expanding your subscriber base and streamline the distribution of messages to a vast audience.

These SMS short codes possess remarkable capabilities, enabling the rapid transmission of a substantial volume of text messages within a short timeframe. On average, they can dispatch over 500 messages per second, rendering them an indispensable tool for SMS marketing campaigns targeted at a massive audience.

While shortcodes are well-suited for straightforward SMS campaigns, such as discounts or promotional offers, they also offer versatility for more creative and engagement-driven strategies. These include:

i. One-Time Passwords and Reset Links

Utilizing short codes to deliver one-time passwords or reset links enhances security and user experience.

ii. Event and Appointment Reminders

Sending timely reminders through shortcodes helps inform your audience about upcoming events or appointments.

iii. Sweepstakes or Giveaways

Shortcodes can encourage audience participation in sweepstakes or giveaways, boosting brand engagement.

IV. Collecting Feedback

Conducting customer feedback surveys via shortcodes provides a convenient and efficient means of gathering valuable insights.

Shortcodes offer both efficiency and versatility in crafting engaging and impactful SMS marketing campaigns.

Types Of Short Codes

Dedicated short codes come in two distinct variants: vanity short and random short codes.

Vanity Short Codes

Vanity short codes are custom-selected numbers businesses choose to align with their brand identity. These unique shortcodes enable companies to establish a memorable association with their brand.

For instance, a craft store might opt for the code 27238, which spells out CRAFT on a phone keypad, while a travel company could choose 872835, representing TRAVEL.

Vanity short codes offer the advantage of being more memorable to consumers, fostering increased brand engagement. Due to their exclusivity and high demand among businesses for text campaigns, vanity short codes typically come with a starting price of $1,000 per month.

Random Short Codes

Random shortcodes, alternatively known as “non-vanity short codes,” consist of numbers that are generated randomly for business use in their campaigns. 

Unlike vanity short codes, where businesses control the chosen number, random short codes are assigned arbitrarily to your business without influencing the number selection process.

One significant advantage of using random short codes is their affordability. These codes cost $500 monthly, making them more cost-effective than vanity short codes. As a result, most shortcode texting activities currently employ random codes due to their cost efficiency.
