Q: How do I create pin codes?
A: You login to your account at https://www.diamondcard.us/login. In the "PREPAID CALLING CARD PLATFORM" section of your administration center click the link "add a card". This will start the process of creating a new prepaid calling card. You can choose a name for your prepaid cards, decide how many cards you want to create, choose a dollar amount per card and click the button. In seconds the system will create your prepaid cards and all the corresponding pin codes.
You can then click to download the pins to your computer.
