Paying the GRE with a voucher

[Dff]

Hey!! I was trying to pay for my GRE exam with a voucher number I got from my scholarship program. I was told I had to choose the credit card option and write my voucher number (instead of a credit card number), but it didn't work because I didn't choose any type of credit card. Does anyone know how this works??

You can only use a voucher by phone, fax, or mail so if you tried to register online it won't work. Calling ETS is the easiest option and then just write down your confirmation number they give you. You can then go on the website and link that confirmation to your account.
