Not when you can generally make a 1 time use card, or a "virtual" card that most brands offer. Granted the only places I've seen this type of verification used is where you're going to buy something anyways.

I give it to a dozen different vendors a month. It's sitting in probably 20 vendors on the web right now just waiting for me to pay with it. I tell it to people over the phone. Giving it as a small charge, verification is the least of my worries.
