Maybe I&#x27;m just paranoid :)<p>If I were building a system that required addresses, I would validate them. Why bother asking, otherwise?<p>I&#x27;m guessing that OP&#x27;s system is designed for systems that require validated addresses.<p>Edit: Once or twice, using gift cards, it&#x27;s been necessary to speak with customer service before they&#x27;d accept the payment. That required a VoIP account. I only did that because I needed a VPS in a particular IP range.
