Short codes, long codes, and personalized SMS senders

Differences between short and long codes

A short code is a number (usually 5-6 digits) used to send and receive SMS and MMS messages, in place of standard 10-digit numbers. Because of their shorter length, short codes are easier to remember, write down, and input than their longer counterparts.

A long code is 10-digits. It looks like a standard phone number and is used by businesses to send and receive SMS and MMS messages, or to make and receive voice calls.

Short codes and long codes can be associated with one sender or shared across multiple senders.

Use a personalized SMS sender

When creating an SMS message, you can personalize the name of the sender using alphanumeric characters (no special characters).

❗️ Important
Many countries, including the US, do not allow sender personalization. Even if you personalize your sender name, it will appear as a short code to your recipients. To help your recipients know who is contacting them, we highly recommend that you always include your business name directly in the SMS message.
