Not knowing what affiliates means, I did what any sane customer interested in limiting spam does — I opted out by calling the number provided: 800-333-9956. It was simple. It asked for my phone number, zip code, and the last four digits of my social security number. It even let me enter multiple phone numbers.
If you’re a Verizon customer, I suggest you also opt-out. That is, unless you want more snail mail to shred. 😉
