Maybe you registered your home phone with the Do Not Call Registry, but did you realize you could also register your cell phone (personal phones only, no business phones)? After a 31-day processing period, you can stop calls from telemarketers for five years. Unfortunately or fortunately at this time of year, political calls can still come through as can calls from charities, telephone surveyors, and from any company with “which you have an existing business relationship, or those to whom you’ve provided express agreement in writing to receive their calls.” Online you can register three phones at once; by telephone you can register only one at a time (the phone you are calling from). If you have already registered and forgotten when your registration expires, you can click on the Verify a Registration button.
