TELEPHONE NUMBERS ABUSED IN MARKETING

When you make a call, to order a sweater from a catalog for instance, you may not want your telephone number to be used later for telemarketing or sold to other companies. Even if your phone number is unlisted you may not have a choice. The Federal Communications Commission has denied to block unlisted numbers from being identified by Caller ID. Between 5% and 15% of U.S. phone customers use caller ID. In addition, businesses have used a service called "automatic number identification," which basically is a sophisticated form of Caller ID that gathers both local and long distance numbers. To prevent your number from being displayed on Caller ID you can dial *67 before each call. The FCC doesn't allow phone companies to charge for *67 numbers, but *67 doesn't work when you use 800 or 900 numbers.
