How many keywords and/or sub-keywords can I have on a shared shortcode?

On a shared shortcode, clients are permitted to have an unlimited amount of keywords and/or sub-keywords (subject to availability).

Unless specifically agreed upon with an Account Manager, a standard Agreement is as follows:

• Inbound SMS services include a primary keyword free of charge. Each complimentary primary keyword must include a system prefix to indentify which module is being used on the shared shortcode. For example, for mBILL the opt-in would be 'ASK {KEYWORD}' to {SHORTCODE}.
• With this convention, clients may use unlimited sub-keywords to identify various services 'ASK {KEYWORD} {SUBKEYWORD}' to {SHORTCODE}.
• Clients may "mask off" the system prefix (IE. ASK) for an additional cost by purchasing a Dedicated Keyword. For example, an opt- in would then be {KEYWORD} to {SHORTCODE}. Clients are allowed to purchase as many keywords as they would like.
• With the purchase of a Dedicated Keyword, clients may also use unlimited sub-keywords to run various services. For example, '{KEYWORD} {SUBKEYWORD}' to {SHORTCODE}.
