If you're on Verizon mobile, call this number. Now.

Verizon Wireless customers who don't feel like having their personal information and account information sold to marketers can opt-out by calling 1-800-333-9956.

A notice tucked into our recent bill told us we had 30 days from receiving the notice to do it. Considering that Verizon just sold 1,000,000 old accounts to a debt-collecting agency who tried to bully people into pay debts that were already paid off or never incurred in the first place, calling this number might be a wise move.
