With the Do Not Call Registry, you may still receive political, charitable, debt collection, information, and telephone survey calls. A company can still call if you’ve recently done business with them, or given them permission to contact you. A company must honor your request if you ask them not to call.

Phone numbers placed on the National Do Not Call Registry will remain on it permanently unless you ask them to remove it.
