You can also find this number on txtNation's website on the Amend Password Implementation page under the "Micropayments" section.

Select txtNation from the "Biller" drop-down menu, and enter your desired Join Form Text. For example: "No Credit Card? Pay by Phone!" Enter your mpcID into the "Biller Code" box.
Save your changes once you have filled out the available fields on this page. txtNation should now be ready and configured to process transactions in NATS3.
