What is a keyword?

A keyword is a unique alphanumeric word that can trigger actions such as an opt-in, opt-out, or auto-response text when text messaged to a specific shortcode.

A shortcode is a 5 or 6 digit number used for enterprise and brand text messaging campaigns. Consumers can send text messages to a short code and receive messages from a shortcode.

Dedicated short code

A dedicated shortcode is a short code owned and operated by a single company.

The process of obtaining and maintaining dedicated shortcodes can be 6-8 weeks or more.

Keywords and Short Codes FAQs

What is the difference between an SMS keyword and an MMS keyword?

The message delivered with an SMS keyword contains only text while the message delivered with an MMS keyword contains the textual keyword plus a piece of content such as an image or video. Both SMS keywords and MMS keywords can trigger either SMS or MMS responses.

Can I release a keyword before it becomes inactive?

Yes. You can delete the keyword you no longer wish to have. This can be done in the “Keywords” tab or within the keyword section of an SMS/MMS campaign.

What is the difference between keywords used in SMS/MMS campaigns and keywords used in MMS Inboxes?

SMS/MMS campaigns use SMS keywords, while MMS Inboxes use MMS keywords. If you acquire an MMS keyword, you will automatically have access to its SMS counterpart, and vice versa. For more information on the keyword types, see the above question “What is the difference between an SMS keyword and an MMS keyword?”

Is there a fee per keyword? Can I purchase more?

You are not charged for the creation of new keywords, but you may be limited to a specific number of keywords depending on your plan.

If I own my own short code, am I limited to the number of keywords I can use?

When you own your own dedicated short code there is no limit to the number of keywords you are allowed. You can also configure the HELP and STOP messages to your own requirements. Your keywords will never expire either until you release them.
