  1. Select Short Code:
    • Opt for the short code option, aligning with your transaction needs.
  2. Enter Organization Code:
    • Input your organization code, typically your paybill or till number.
  3. Organization Names:
    • This step is a potential minefield for errors. Input your business name used during the paybill registration. Crucially, keep it to a single word. For instance, if your organization is ‘Bima Enterprise Limited,’ use only ‘Bima.’
  4. Mpesa Username:
    • Retrieve the username provided in the approval email. This should be entered precisely in the designated field.
  5. Subject Line Matters:
    • When searching for the approval email, look for the subject line “Create Organization Operator.” This is a key element to identify the right correspondence.

Common Pitfalls

While the process may seem straightforward, pitfalls often lie in the details. Organization name discrepancies, especially using more than one word, can trigger errors. Always cross-verify your entries against the information provided during the approval stage.
