Once all the steps for your online transfer are completed, a confirmation screen will pop up right away. After you visit a participating agent location and pay for your transfer, an MTCN will be generated and you will be given a receipt. After this, the funds will be sent. The receipt is the confirmation that your money transfer has been sent.
Remember to share the MTCN with your receiver, as they will need it to pick up the money. When your receiver collects the money, you'll get an SMS confirmation message or an email.
