What is a Short Code?
First, it is essential to understand the terminology. A “short code” is a special, abbreviated phone number, typically 3 to 6 digits long, used by businesses and organizations to send and receive text messages. These are most often used for automated communications like security alerts, marketing promotions, or service notifications. A key principle of short codes is that they are country-specific; a short code used by a company in one country is often used by a different company or is not used at all in another.
