There are two key elements when advertising your texting service: the keyword and short code. A keyword is a word or phrase that's synonymous with your brand and can be texted to your number to sign up for future text messages. Non-subscribers, people who have not yet joined your contact list, will text this keyword into a 5-digit number called a short code. When they do, they will have joined your contact list, and be added into a group that corresponds with that keyword.

The standard way of expressing this is:
"text KEYWORD to SHORT CODE to join"

How To Find Your Keyword and Short Code

Step 1:

In the top right corner, you will see your short code. If you do not, contact your sales representative so you can be given one.

If you do not have one or have more than one, your account will say View Numbers which will show you all the numbers on your account.

Step 2:

Click on Groups & Keywords tab in the side bar to find/make/change a group's keyword.

Step 3:

Click on the Edit Group button to find its keyword.

Step 4:

You can see your current keyword or an empty box next to Keyword. In this box, you can type in a new keyword.

After typing in a new keyword, press Check Availability! If no one is using it, its yours.

Step 5:

Hit Save Group at the bottom.
