To find out the origin of the sender id, break the code into two to find region or sender. Though the above list might not cover all of them, you have the idea why there was no number displayed.

If you are getting a lot of promotional messages even though you have registered your number using DND feature, then find out how you can complain about such telemarketers.

Note: If you are using anything other than the default SMS app on your phone, the chances are that you will not see this format. Those apps only display the primary name. So, for example, VK-HDFCBK displays as HDFCBK for me in the SMS organizer app.
