One of the most important element when sending SMS messages via API is how to set SenderID to be displayed on the receipients' devices. Because this tells the recipients who sent them the message.

K-premium service on Xoxzo enables the users to set the Sender display by attach the pre-registrered number as a parameter.

For KDDI/Docomo/Rakuten: pre-registered number
For Softbank: a default shortcode

An update on the shortcode

The shortcode being used as Sender to the Softbank recipients is updated from 5 digits to 6 digits.

Previous Shorcode: 22472

New Shortcode: 249200

A new function: Get your own shortcode and catch the recipients' replies

We will organize your own 6-digits shortcode upon request. In addition, what this new 6-digits code can do is that you can receive your message recipients' replies at a set webhook!

Please contact for further details.
