Why does it say verification required every time I try to purchase something in the iTunes Store?

Hello chanel119,

Thanks for choosing the Apple Support Communities. If we understand correctly, you are unable to make purchases in the iTunes Store, as it states verification is required.

To start, are you using a payment method on your Apple ID? Also, what does the exact message say?

Also, if using a payment method, have you ensured it is an accepted payment method?

Cheers!
