We can certainly look into getting a short code for you. Given the nature of short codes, however, a dedicated short code will generally cost between $1000 and $1500 per month.
The benefit of short codes is that they are built more for marketing and promotional messages, which are not allowed through 10-digit phone numbers. If you are interested in pursuing a short code, feel free to text us at (415) 849-4349 to discuss.
You can also acquire a short code from Twilio and set up Textline to use the API credentials provided by Twilio for your shortcode. Details on setting that up can be found here.
